The technical field of the invention

The present invention relates to the form for continuous casting of molten metal and casting, which includes the system of distribution of heat or temperature control mold or shape for the billet, system expansion for forms for continuous casting and system adjustable length of the working surface of the mold.

Background of the invention

Metal ingot, billet and other cast parts can be obtained by the method of casting using vertically oriented foundry form located above a large foundry opening below the floor level facilities for casting of metal, although this invention can also be used for horizontal casting forms. Lower component vertical mold is the seed unit. When begins the process of casting, bare blocks are in their extreme top position in casting patterns. When the molten metal is poured into the hole mold or cavity and cool (usually water), the seed unit slowly lowered to the level specified hydraulic cylinder or other device. When the seed unit is lowered, hardened metal or aluminum goes through the bottom of the mold, and formed bars, round billets or billet different geometrical shapes, which can also be called cast parts.

Although the invention, in General, apply to the casting of metals, including not as a constraint aluminum, brass, lead, zinc, magnesium, copper, steel, and similar examples and disclose the preferred embodiment of the invention may be sent to aluminium, and consequently the terms aluminium and molten metal can be used everywhere for consistency, even if the invention is applied to the metal in a more General sense.

Although there are numerous ways of obtaining and execution devices vertical casting, Fig. 1 shows one example. In Fig. 1 vertical aluminium casting, in General, is in the foundry opening below the mark of the factory floor. Under the floor of the foundry opening 101 has a caisson 103 hosting sleeve 102 hydraulic cylinder.

As shown in figure 1, the components of the lower stretch of vertical device aluminium casting, shown within the foundry opening 101, and caisson are 103 sleeve 102 hydraulic cylinder, the piston 106, casing 105 installation of a support base, support table 107 of the plunger and the basis of 108 bare block (also called the seed or bottom plate), all shown on the grades under the floor 104 foundry facilities.

Casing 105 installation supports are installed on the floor 101a foundry opening 101, and beneath it is a caisson 103. Caisson 103 limited its side walls 103b and their bottom 103a.

Typical Assembly 110 moulding table also shown in figure 1, the Assembly can be shifted, as shown hydraulic cylinder 111, push the lever 110a offset moulding table so that it revolves around the point 112 and thus raises and turns the main Assembly foundry frames, as shown in figure 1. There are also trucks for forming the table, which moves the Assembly moulding table toward positions for casting over foundry opening from it.

Figure 1 also see the reference table 107 plunger and 108 basis of the seed unit, partially descended into foundry opening 101 with partially completed cast item 113 (which may be an ingot or Billiton). The casting 113 is based on the 108 seed unit, introduced in the beginning of the process, which may include the bare nozzle or the lower plate, which is usually (but not always) is based on the 108 seed unit, which is known in the prior art, and there is no need for this reason, their show or describe in more detail. Although the term seed unit is used for item 108, it should be noted that the terms of the bottom plate and the seed nozzle is also used in industry to denote the position 108, bottom plate, usually used when cast ingot, and the seed attachment - when the cast billet.

Although the basis of the seed unit 108 figure 1 shows only one seed unit 108 and tables, as a rule, several blocks and tables set on each basis of the seed unit, while casting billet, special conical forms or configurations, when the seed unit is lower in the casting process.

When the working fluid is injected into the hydraulic cylinder under enough pressure plunger 106 and, therefore, the seed unit 108 raise the level of initial level required for the process of casting, with bare blocks are in the Assembly moulding table 110.

The descent of the seed unit 108 perform dosing issue of the working liquid from the cylinder with a given flow, thus there is a lowering of the plunger 106 and, therefore, the seed unit for a specified and regulated level. Mold adjustable cooled during the process to facilitate the solidification facing ingots or billet, usually with the use of means of water cooling. Although this document describes the use of a hydraulic cylinder, specialists in the art should be clear that it is possible to use other mechanisms and ways of lowering of the table.

There are many forms and casting techniques that are appropriate to the forming tables, and no special of them required for the practical implementation of the various options for the implementation of the present invention, as they are well-known specialists in the field of technology.

The upper side is typical moulding table functionally connected or interacts with the system of allocation of metal. Typical moulding table, are functionally connected with foundry forms, which he holds.

When the metal is cast with the use of forms for continuous vertical casting, molten metal is cooled in a mold and continuously extends from the lower end of the mold when lowering the seed unit. Facing billet, bullion or other configuration must enough to harden, to maintain the necessary form. In some casting technologies can be an air gap between emerging hardened metal and permeable ring wall, while others may have a direct contact. Below there is also air the mold cavity between facing hardened metal and bottom section of the form and its associated equipment.

Upon completion casting castings, billet in this example, out of the bottom plate.

In this process, in General, it is necessary to aspire to a more uniform distribution of the temperature of molten metal, supplied in the form of the distribution system of molten metal. Task some options for the implementation of this invention is to provide usovershenstvovanija mechanism, means and/or the filing of molten metal from the distribution system of the molten metal into the mold cavity.

Also required during casting of molten metal, and it is the task of embodiments of the present invention, such as the forms for billet large diameter, is to obtain an improved method of centering transition rings. Additionally necessary, and also an object of the invention, the creation of such a method of centering transition rings, in which the ring remains centered during the expansion and contraction resulting from bringing in and removal of significant amounts of heat generated as a result of casting processes.

In the casting of the molten metal is also necessary movement to optimization parameter, referred to as "the length of the channel" build forms, and advanced task of some embodiments of the present invention is to create a system change the channel length build forms that provide a relatively simple change to the length of the channel forms.

Other tasks, the characteristics and advantages of the present invention will become apparent from a detailed description of the invention, the claims and the accompanying drawings that make up a part of him. When solving problems of the present invention must understand that its essential features subject to change in the pattern and structure of the device, because only one practical and preferred embodiment of the invention shown on the attached drawings, as required.

Figure 2 shows an isometric view of one of the example of the Assembly nozzles that you can use options in the implementation of the present invention. In Fig. 2 shows a system 150 nozzles for submission of molten metal, building 151 nozzle section 151a sign of molten metal, the main plot 151b corps, hole 160 nozzles, through which molten metal is delivered in a form Assembly, internal trench 153 for molten metal and openings or gates 155 and 156 for molten metal in sections 154 inner wall, through which molten metal should come from domestic gutters 153 through the gates 155, 156 and other, and through the hole 160 nozzles in the Assembly of the form. The external wall 149 nozzles (or external enclosing wall of the nozzle) protects the molten metal from the outside and the inner wall 154 nozzles or barrier protects the molten metal and creates an element regulate its flow from the interior of internal trench. The metal stream through the gates 155 and 156 are represented by arrows 170 and 171, respectively. Although only two sprue molten metal or holes 155 and 156 the corresponding positions, and also shows other gates, and the specific number of gates or holes used in any particular system Assembly nozzle can be adjusted on the basis of the application, that the invention does not contain specific requirements for the number of gates or holes or their size and configuration for the practical implementation of the invention. Drain socks or lower ends of the square of casting can change to get the required characteristics of a stream of molten metal, or may change the height of the drain sock sprue, affecting the flow of molten metal in this version of the application, all this is within the scope of the invention.

The molten metal is injected into the Assembly 150 nozzle through the intake chute 152 and then passes through the inner groove 153 and then through the gates or holes (position 155 and 156, for example) into the hole 160 nozzles. That is the description of the process at startup time. During startup, the molten metal in the beginning serves on the bottom plate installed in oral form, and the level of the molten metal rises, and over time must be attained conditions of the established mode. At steady state flow regime the level of the molten metal should, in General, to remain above the bottom section of the gates to molten metal and metal must receive a steady stream from the input chute 152 internal trench 153 and through the gates with the level of the metal, partially risen to the top of the gates. In one example, the level of the molten metal can support about the middle height molded or holes.

In Fig. 2 also see the sections 154a, 154b, 154c, 154d, 154e and 154f inner walls, creating the internal side of the barrier for internal gutter 153 and also forming the corresponding gates for molten metal or holes. Specialists in the art should be clear that the invention must involve various configuration, size and location of the gates to the molten metal into the inner wall 154 (combination areas 154a, 154b, 154c, 154d, 154e and 154f internal walls) of the Assembly 150 heads. In some embodiments of the invention may be that the gates at various heights as regards the internal gutter 153. May also be necessary in some embodiments of the invention changing the width of the gates or other parameters to control the characteristics of flow and, in turn, regulation of temperature distribution molten metal during its flow through the hole 160 nozzles and in shape. In some embodiments, the implementation should be necessary, for example, the execution of the gates asymmetric configurations, namely a larger number of gates on one side or the square of the gutter, opposite the inlet spout 152, or these gates can be installed above or below, or create greater consumption on the sprue changing dimensions (height sock, width, or other parameters sprue concerning square sprue), all this is valid within the scope of the present invention.

In some versions of the application or options, the implementation of this invention, it is necessary to perform internal tray 153 certain size relative to the gates for more uniform flow through the gates. In some embodiments of the invention getting smoother flow around the circumference of the system nozzles should lead to the achievement of better temperature distribution and regulation of heat exchange in the form region, which serves the molten metal. In some embodiments of the invention may be necessary to get more high speed feeding molten metal through the gates and getting better teplonositelya or temperature distribution in the molten metal is supplied to the region Assembly of the form, all this is possible within the scope of the invention. In General, it is necessary to obtain in the form of more uniform teplonositelya and distribution of the temperature of the molten metal at its filing in the form and at its solidification, resulting in higher quality or more preferred cast item.

Options for implementation and configuration of the Assembly attachments specifically suited for use in forms for moulding of large diameter, such as forms for billet. Although the terms "all" and "diameter" is used in this document with reference to the cast parts and the holes in the Assembly forms, also specialists in the art should be clear that the invention is not limited to all sections of the form or manufacture of cast parts with round cross-section, but instead should be applied to elliptic cast parts and other parts of the geometry and the configuration, all permitted within the scope of the present invention.

In Fig. 3 shows an isometric view of a disassembled form Assembly one example that can be used in the variants of the invention. In Fig. 3 and subsequent figures as an example shows the configuration of the transition plate with automatic alignment with the regulatory mechanism of expansion of the form. In Fig. 3 shows the system 200 forms for molten metal, which includes thrust ring 201, the adapter plate 202, foundry ring 204, 205 corps forms with mounting parts 205a housing forms for fastening the housing form with other components, afflux 206 hull form, separating plate 207 and ring 208 water spray.

Molten metal should be adopted from the device of the distribution of molten metal, such as a system of nozzles, are shown in Fig. 2 through the opening 210 form, and during the cooling process should be hardened at the exit through the bottom or bottom-site Assembly of the form shown in Fig. 3. During startup, the seed unit or head is installed in the cavity of the form to create the lower surface, where the casting need to harden. After filling with molten metal mold cavity and its solidification of the seed unit is lowered and hardened or partially consolidated the casting comes from the bottom of the mould cavity. The process continues until a cast details required length.

In Fig. 5 shows the item 5 in Fig. 4. In Fig. 5 to view the details section of Fig. 4 shows the thrust ring 201, foundry ring 204, transition stove 202, cavity 219 forms, building 205 form, separating plate 207, ring 208 water spray, supply 213 water with a jumper 214, throwing water 216 coming out of the ring 208 water spray, to create water cooling of the casting moving through the form.

In Fig. 5 additionally shows how the ring round section 233 established under the pressure between the stop ring 201 and transition stove 202, which, in turn, passes downward pressure on the incline surface 202a transition plate 202 on an inclined surface 204a at the foundry ring 204, as shown in the angular profile between them. Although inclined 204a at the foundry ring is inclined, outer fillet can also be used for better alignment of the surface to interact with inclined surface 202a transition plate. When thrust ring 201 concise and shape are assembled, installed pressure between the inclined surface 202a transition plate 202 and inclined surface 204a foundry ring 204.

In variants of the implementation of the present invention Assembly transition plate 202 relatively foundry ring 204, especially on forms for billet large diameter should be relatively accurate to create the necessary installation. However, this accuracy is affected by thermal expansion and contraction that occurs when entering the hot molten metal, and then remove the metal. This system extension is also the sign of automatic centering that when the adapter plate 202 install, it automatically centers due to the interaction inclined surface 202a on adapter plate 202, United with inclined surface 204a at the foundry ring 204 for proper installation of the plate in place. When thrust ring 201 fasten with ring 233, of circular cross between him and transition stove 202, this gives a relatively accurate and centered Assembly transition plate 202 relatively foundry ring 204, and the use of ring 233 round section creates in this connection, pressure, or interact with preliminary displacement, continuously providing the necessary installation transition plate 202 in place regarding foundry ring 204, including installation during thermal expansion and contraction.

Specialists in the art should be clear that while the ring round section 233 used in this example, options for implementation, other mechanisms can be used to offset transition plate 202 down at the foundry ring, such as plate or other springs, with the invention does not contain specific requirements mechanism for the implementation of the present invention.

In Fig. 5 also shows the position 217 what in the art called a channel length of this form. The length of the channel, in General, define or identify from the transition area where metal meets foundry ring 204 in this version of the application, to the place where the discharge of water indicated on the bottom point brackets 217 representing the length of the canal. Refrigerant or water 216 coming out of the ring 208 water spray, creates the second anchor point for measuring the length of 217 channel, i.e. the point where the water discharge.

At various speeds casting must be of a different length of the channel for specific castings. In many cases have to use a different form with different channel length and different form should be created beforehand and made a predefined length of the channel (which can not be controlled via the existing components). Aspects of this invention, however, involve the use of many of the separation of plates 207 various thickness, so the separating plate 207 can be replaced with thicker dividing plate and change the channel length, without replacing the entire form necessary for this application. This system is a control system in the channel length. Figure 6 is shown below a separating plate 235 thickness, different from the thickness of the dividing plate 207 (shown in Figure 5), inserted in a similar form Assembly. Separating plate different size creates the length 218 channel, different or not equal to the length of 217 channel, shown in figure 5. All other items on 6 similar positions on 5 and need not be repeated here.

Figure 5 also shows the arrow 236 representing the metal stream via the adapter plate to 202 foundry ring 204, which created pipelines for oil distribution foundry ring, passing through foundry ring to oral 219 form during the casting process. Arrow 236 shows the flow of the molten metal to cast ring 204. Bolt 238 rings water spray and bolt 239 dividing plate shown fastening components together form Assembly.

In Fig. 6 additionally shows how the ring round section 233 established under the pressure between the stop ring 201 and transition stove 202, which, in turn, passes downward pressure on the incline surface 202a transition plate 202 on an inclined surface 204a at the foundry ring 204, as shown in the angular profile between them.

If sloping surface a foundry ring inclined, can be used rounding to ensure the best alignment for interaction with inclined surface a transition plate. When thrust ring 201 concise and shape are assembled, installed pressure between the inclined surface 202a transition plate 202 and inclined surface 204a foundry ring 204.

In variants of the implementation of the present invention Assembly transition plate 202 relatively foundry ring 204, especially on forms for billet large diameter should be relatively accurate to create the required accuracy of installation. However, this accuracy is affected by thermal expansion and contraction that occurs when entering the hot molten metal and subsequent removal of metal. This system extension also has the effect of automatic centering, by which, when the adapter plate 202 install, it automatically centers due to the interaction of the incline surface 202a on adapter plate 202 of the inclined surface 204a at the foundry ring 204 for proper installation of the transition plate in place. Then, when thrust ring 201 fasten with ring 233, of circular cross between him and transition stove 202, this gives a relatively accurate and centered installation transition plate 202 relatively foundry ring 204, and the use of rings 233 round section creates in this connection, pressure, or interact with preliminary displacement, providing continuous hold on the desired location transition plate 202 relatively foundry ring 204, therefore, is of the form when thermal expansion and contraction.

Specialists in the art should be clear that while the ring round section 233 used in this example, options for implementation, you can use other mechanisms to offset transition plate down on the casting ring, such as plate or other spring, however, the invention does not require the use of specific mechanism for the practical implementation of this invention.

In Fig. 6 also shows the position 218 that in this art called by the length of the channel forms. The length of the channel, in General, establish from the transition area where metal meets foundry ring 204 in this version of the application, to the place where the discharge of water indicated on the bottom point brackets 218 (representing the length of the channel). Water 216 coming out of the ring 208 water spray, creates the second anchor point.

At various speeds casting must be of a different length of the channel for specific castings. In many cases have to use different forms with pre-made and pre-defined length of the channel, which, in General, impossible to regulate. Aspects of this invention, however, provide for the use of multiple separator panels (such as position and 235 207) of different thickness, so the separating plate, such as 207, you can replace thicker separation stove, such as separating plate 235, this changes the length of the canal without changing all the forms required for this application. In Fig. 6 shows the separating plate 235 different thickness from dividing plate 207 and inserted in a similar form Assembly, this creates length 218 channel, different or not equal to the length of 217 channel shown in Fig. 5. All other positions in Fig. 6 similar positions in Fig. 5 and need not be repeated here.

Changing the channel length in this embodiment of the present invention can also perform one or more of a number of different ways, including: creating an Assembly forms without dividing plates and then adding one or more of the separation plates to change the channel length form; or the creation of many of the separation of plates of equal thickness, which can be used for various lengths of the channel in the same form (either initially without dividing plates and with the addition of one or more, or beginning with one or more of the separation plates then add or remove if necessary); all this is valid within the scope of the various options for the implementation of the present invention.

Figure 6 also shows arrow 236, representing a stream of molten metal through the adapter plate to 202 foundry ring 204, which created pipelines for oil distribution foundry ring, passing through foundry ring to oral 219 form during the casting process. Arrow 236 shows the flow of the molten metal to cast ring 204.

7 shows the same item 5 in Figure 4, is shown in Figure 5, in which there are two separator plates of equal thickness, that is shown the same form with different length of the canal. Position 7 are similar positions at 6, with the addition of first dividing plate 236 and the second dividing plate 240 shown the same thickness, but which may also have different thickness.

On Fig shows a detailed view of section 8 to 5, and shows the flow of 236 metal and cavity 219 form undergoing transition from plate to 202 foundry ring 204. Specialists in the art should be clear that the oil is passed through foundry ring 204, creating a lubricant on the inside surface of foundry ring 204 in contact with molten metal 236 going down.

On Fig shows the interface between transition stove 202 and foundry ring 204 on an inclined surface a transition plate 202 and inclined surface a foundry ring 204, which in this example case for both shows approximately or relatively flat.

Figure 9 also shows item 8 to 5, but in which the fillet 199 shown on the incline surface 204a foundry ring 204. Specialists in the art should be clear that as the inclined plane 204a foundry ring 204 and inclined 202a transition plate 202 can have external fillet (as shown in Fig. 11), or both may be flat sloping surfaces (as shown in Fig. 8), or that the inclined plane 202a transition plate 202 can include external fillet (shown in Fig. 10), such as shown by the position 198, combined with inclined surface 204a foundry ring 204, which is approximately flat. You should also understand that the fillet 199 Fig. 9 and rounding 198 in Fig. 10 can be of any radius from a number of different values depending on the type of application or variant of implementation, with the invention does not contain specific requirements to data values for the implementation of this invention. Shows the outer fillet exaggerated for clarity, the necessary fillet for any particular application varies based on several factors (such as the diameter of shape, configuration foundry rings and configuration adapter plates). All other positions are identical to that shown in Fig. 8 and shall not be repeated here.

In Fig. 10 also shows the item 8 in Fig. 5, in which the fillet 198 shown on the incline surface 202a transition plate 202. All other positions are identical to that shown in Fig. 8 and shall not be repeated here.

In Fig. 11 also shows the item 8 in Fig. 5, in which the fillet 199 shown on the incline surface of foundry ring 204 and rounding 198 also shown on the incline surface 202a transition plate 202. All other positions are identical to that shown in Fig. 8 and shall not be repeated here.

In Fig. 12 shows the cross-section one example, the Assembly nozzles vertically above the Assembly of the form, which you can use options in the implementation of the present invention. In Fig. 12 shows the system 150 nozzles for molten metal, such as shown in Fig. 2 and more fully described above, vertically over the Assembly 250 forms, described more fully above and shown in Fig. 4, with a stream of molten metal, represented by the arrow 163 between 150 nozzles for molten metal and Assembly 250 of form. The casting 271 seen coming from the bottom Assembly 250 of form and arrow 272 shows that the casting is gradually lowered during solidification of the molten metal, supplied in the form, this creates the casting 271, which can also be referred to as Billiton.

In Fig. 12 shows the case 151 nozzle inlet section a corps nozzles and the main plot 151b hull attachments. Gates nozzles or holes 157, 158 and 159 shown in Fig. 12 with a stream of molten metal, specified through the gates 157, 158 and 159 arrows 175, 176 and 177, respectively. Internal trench 153 shown in the housing 151b sockets and wall 154 nozzles is shown between the inner groove 153 and hole 160 in the system 150 nozzles for molten metal (shown on other shapes). The intake chute 152 shown in the intake section 151a hull attachments. Specialists in the art must be clear benefits or potential benefits of using customizable channel length in system of interchangeable separating plates for this form. For example, the benefit may be that fewer forms in the foundry or optimize the length of the canal, the quality of the resulting cast parts must be improved more simply and cost-effectively.

Although in industry standards may be a different definition of the length of the channel in General, the length is defined as the distance between the point where the molten metal contacts with the casting surface, to the bottom of the sock, where the water discharge on the molded part. This distance, in General, has a different value in the molding process, and the resulting cast detail, and in some versions of the implementation of the distance of discharge water determines how far up toward the foundry ring is the solidification of the molten metal. Usually the task of the casting process is to optimize the length of the channel for a given speed of casting and mould Assembly. The data provide one system build forms with numerous separating plates, creating opportunities flexibility and optimization for the customer.

In variants of implementation of the system of extension of transitional forms stove or "T-plate"as it is sometimes called in the industry, becoming a floating because not fixed in one position and because it has an inclined surface, interacting with the opposite inclined surface at the foundry ring, and pulled down or pre-offset spring on the T-stove (in the variants of implementation, shown in this description is the ring). In the configuration for all of the casting, where transition stove is in the common round, and foundry ring is in General all, the combination of the offset down and to the opposite inclined surfaces creates the effect or the advantage of automatic centering. Denial of proper centering transition plate leaves or may leave an open stretch of transition plate, which should be destroyed faster than if it has the best centering, and the destruction of the transition plate should affect the quality of surface obtained as a result of the casting or billet. This extension system not only creates the best mechanism of automatic centering, but also because the transitive plate is under the constant shifting of force or forces from the ring, it creates this centering, which can, in General, support during the expansion and contraction of the Assembly forms from heat, introduced the molten metal. Aspects of this invention can help reduce or prevent the destruction of which should occur in systems of prior art. Also, experts in the art should be clear that other mechanisms applications bias forces, such as a spring or plate spring, can be used instead of the rings, with the invention does not contain specific requirements to the mechanism for the practical implementation of this invention.

Although aspects and ways of implementation of the present invention are good applicability for forms of the big diameter, the invention or various aspects of the invention in such application is not limited. When using the term form of large diameter, in General, mean shape with a diameter of 20 or 21 inches or more.

Specialist in the art should be clear that there are many ways to implement this invention, and change elements and components that you can use, and they are all within the scope of the present invention.

In one embodiment, created, for example, the delivery system of molten metal for continuous casting of details in the form of a billet, containing: housing tips for distribution of molten metal, consisting of external the enclosing wall of the nozzle and the inner wall of the nozzle, concentrically installed in the external enclosing wall of the nozzle; the inner wall of the nozzle, environmental and forming a feed opening of molten metal in the form of billet and includes many of casting of molten metal on the inside wall of the nozzle and executed with the possibility to create channel flow from the interior of the gutter to the feed opening; and intake chutes, functionally connected to the internal chute and set with the possibility of reception of molten metal and its supply in the internal trench in the case of the nozzle.
