(i) the use of The invention relates to a device for Baskakova pyrometallurgical processing of metallurgical wastes (slags, blast furnace dusts, oil slag and others) and non-ferrous and/or nonferrous metals, in particular containing refractory education, and difficult to process in conventional furnaces (blast, mine and others), as, for example, titanium-magnetite ores. (ii) Prior art When processing metallurgical waste in such furnaces, as a domain, mine and so on, requires prior preparation of the mixture to heat (enrichment, briquetting, balling and agglomeration of the charge). At this stage deadweight loss iron exceed 20-25% (the bulk of losses occurs when the ores). As fuel in such furnaces can only use coarse expensive and in short supply of coke. In addition, removal of dust from flue gases usually exceed 15% or more of the weight of the loaded charge. All this taken together makes traditional melting economically unprofitable in the processing of ores and industrial wastes and hazardous, and the furnaces in these cases, it is difficult to be automated and controlled. On the other hand, the processing of ores of iron, such as titanium-magnetite ores, which require high-precision control flowing in the furnace processes. Currently, the most promising from an economic and environmental point of view are Vanyukov furnace and furnace similar type, in which Baskakova pyrometallurgical processing of materials containing non-ferrous, ferrous metals and refractory education. However, such furnaces have several disadvantages. Smelting and metallurgical recovery of raw materials, particularly those containing refractory materials, such as Titano-magnetites, there are significant problems associated with the formation of refractory growths on different parts of the furnace, which leads to malfunction of the furnace or a major incident. Also during operation of the furnace with increasing viscosity of the slag is a mechanical grip of the metal layer produced from a bath of slag, which leads to loss of metal from the slag stream. To avoid these problems, you need to be able to controlled the local high-temperature heating at the boundary of the slag and metal phases, and deposits of refractory compounds. In addition, operating experience from metallurgical furnaces known that for efficient operation it is necessary to continuously maintain the specified level of slag and metal, and more importantly, the level of the boundaries of the partition. Known one zone furnace for continuous plank the sulphide in the liquid bath, containing a rectangular shaft, caisson belt with lances, the furnace hearth and fixtures for production of slag and matte tapping (siphons). Siphon for the production of slag communicates with the shaft furnace using peritoneo window in the end wall of the furnace and provided with electrodes. Arbitrarily set the trap electrodes are used for heating, vertical circulation and stabilize the temperature of the upper slag layer, equal to the height of the penetration electrodes. The level of the metal and slag in the bath is adjusted by changing the height of the drain thresholds siphons for production of liquid products of fusion (A.S. 1316367, F27B 17/00, publ. 15.03.1988 year). The disadvantage of this invention is that the upper section and the lower layers (surfaces) of the liquid molten metal and slag accumulate refractory compounds, which eventually leads to the obliteration of walls and nozzles siphon, and also entails arbitrary changes in the level of molten metal and/or slag in the siphon. In the result there is a need for emergency or forced stop of the oven. On the other hand, it is impossible to create local heating at high temperature under surfaces of the metal and slag in the siphon and the lowest cost of electricity and other fuels. This, in turn, helps prevent mechanical grip metal height is kewaskum layer produced from a bath of slag, which leads to the loss of metal from the slag stream. Another disadvantage of this furnace is the difficulty of maintaining the required level of slag and metal in the furnace, because the idea of regulating the height of the drain thresholds, depending on the composition of the charge in practice unworkable. For example, when the processing of industrial metallurgical waste rate of change of the charge is very high and not controlled, and the change in height of the drain thresholds because of overgrowth of refractory compounds require stopping the oven. The closest technical solution is Vanyukov furnace for continuous melting of materials containing non-ferrous and ferrous metals (RF patent No. 2242687, F27 17/00, publ. 20.12.2004). The furnace includes a rectangular bottom and extending in the upper part of the caisson shaft; a transverse partition separating the shaft furnace at the camera oxidative melting of charge and camera recovery of oxides of the slag, and the camera is equipped with lances. The furnace also contains stage furnace hearth, the siphon with holes for release of slag and metalloceramic phase; pipes for exhaust gases from the chamber recovery and camera oxidative melting device for loading particulate material into the chamber of the recovery device for loading particulate material into the chamber oxidative melting. The difference of this constructivley, that the lower edge of the septum from the camera oxidative melting installed on 5-15 diameters lance camera oxidative melting point below the axis of these tuyeres. The upper edge of this partition is located above the axis of the tuyere camera recovery 2.5-4.5 distances from the axis of the tuyere camera recovery to the threshold of the outlet openings of slag. The main disadvantages of the above invention are as follows. During operation of the furnace, the formation and accumulation of refractory compounds between the channels for the production of slag and metal, which, in turn, can create a dangerous emergency, such as a complete blockage of the cross-section of the siphon. Local refractory materials can also napravljaetsja or fixed in the form of growths on the different elements of a siphon. Not surgical removal reduces the stability and reliability of continuous operation of the furnace. In addition, the impossibility of continuous or rapid temperature changes at the interface of the upper metal level and the lower level of the slag in the bath siphon leads to loss of metal, mechanically carry out the viscous flow of slag. The impossibility of carrying out continuous or, for example, every 10-15 minutes, control the level of the metal and slag reduces the controllability of the process in the nna oven. It is also impossible to prevent the entry of slag into the channel for the release of metal that may cause a low-grade metal and will require additional separation of the slag from the released metal from the furnace. In local zones pipes for venting this furnace, as in all traditional coal mines, blast furnaces and furnaces fluidized bed, there is an accumulation of fine carbon, which can lead to explosions with major destruction and the tragic consequences for staff. The proposed construction of the furnace allows to solve a number of technical challenges. First, you receive the possibility of continuous or virtually unlimited frequency to submit additional heat directly in the coupling zone of the metal layer with the slag, and in the pockets of refractory compounds. This allows to reduce the viscosity of the slag and furnace to melt the buildup of refractory materials not only from the walls of the siphon, but in all areas of the siphon on the furnace hearth, perechodnik channels. Second, the invention allows automatic or remotely at the request of the operator to monitor changing levels of slag and metal in the bath siphon and timely issue control actions to maintain the specified values. The possibility of direct measurement of UB is the metal and slag allows you to control the completeness of their release from the bath of the furnace, in this connection eliminates the danger of slag in the channel for the release of the metal. Third, in the proposed furnace eliminates the possibility of accumulation of fine carbon and other combustible substances in the pipes for the exhaust gases which are burned in the vertical risers of these pipes, and released heat is removed by evaporative cooling system risers for future use. Fourth, the siphon furnace can be used for refining of slag and metal, for example for the removal of such undesirable impurities as phosphorus, sulfur, and others. (iii) Disclosure of inventions The solution of the above technical problems is achieved by the fact that in the oven to melt in the bath liquid materials containing non-ferrous, ferrous metals and refractory education, including caisson shaft, separated by a transverse partition into melting and recovery of the camera, provided with upper and lower tuyeres; the furnace hearth; at least one trap for accumulation and release of the metal and slag through the appropriate channels having at least one window in the lower part of the end wall; a loading device of the charge and solid material in the melting and the recovery chamber; at least one pipe for exhaust gases installed on the roof of the furnace, ACCORDING to the INVENTION, cipangopaludina provided, at least one sleeve for insertion and movement of the electrode; block manipulation electrode; a current source; a unit of measuring instruments and automation; the upper part of the electrode connected to the power source and the power control instrumentation and automation, and the output of the latter, in turn, is connected to the input of block manipulation, providing through the drive electrode of the vertical reciprocating movement, as well as the deviation from the vertical axis. On the furnace hearth furnace, near the location of the open bottom end wall of the siphon can be installed grounding device. The sleeve may be provided with a valve. The siphon may contain in the upper part of the channel for exhaust gases, which is communicated with the upper nadgortannuu area mines oven. Pipe for exhaust gases may contain riser for post-combustion of combustible substances in the waste furnace gases. Between the arch of the furnace and the bottom edge of the riser pipe for exhaust gases can be installed to a device for controlling the negative pressure under the arch of the furnace and air supply. The furnace hearth furnace can be made flat, stepped or inclined. Transverse partition between the melting and the recovery chamber may contain one or more of the Windows located at the lower edges of the partitions. (iv) Description of drawingThe invention is illustrated in the drawing. The drawing shows a longitudinal section of the proposed furnace. The structure of the furnace consists of: caisson shaft 1; tuyere bottom row 2, 3 (the number of tuyeres depends on the size and productivity of the furnace); lance top row 4; the transverse partition 5 (submitted version without window); melting chamber of the furnace 6; regenerative furnace chamber 7; the siphon 8 with a channel for directing gases 9, communicating with the upper nadgortannuu zone furnace (siphons may be several depending on the geographic location of the furnace in the shop and quantity of product mix: slag, metal, matte, and others); end wall 10 with box in the lower part for flow of melt from the recovery chamber 7 in the siphon 8; electrode 11, which is inserted into the siphon through the sleeve 12 in its roof; block manipulation 13 drive 14 of the electrode 11, the current source 15, and flow measuring devices and automation 16 (sensors)connected to the upper end of the electrode 11, and the output of the measuring devices and automation 16 is connected to the input of block manipulation 13. The furnace also includes a pipe for exhaust gas 17 to the riser 18 for the afterburning of exhaust gases; a device for controlling discharge under the arch of the furnace and air supply 19; isolated from the chassis PE and the grounding device 20; a device for loading mixture or solid materials into the melting chamber of the furnace 21; a device for loading solid materials (reducing agents) in the reducing chamber of the furnace 22. (v) Examples of carrying out the invention The oven works as follows. The charge flux additives and solid fuel load through the device 21 to the surface Bartiromo blown slag melt in the melting chamber 6. The splashing of the melt and the oxidation of the carbonaceous fuel is carried out by supplying the oxygen-containing melt blown through tuyeres 2 in the side walls of the furnace, installed in an amount necessary for complete combustion of combustible components with maximum heat. Due to the intensive mixing and heat of combustion of the solid fuel charge quickly melts and forms a homogeneous slag, which as it accumulates in the bath melting chamber 6 through the upper edge of the partition 5 flows into the upper part of the recovery chamber 7. For this node furnace it is necessary that the lower edge of the partition 5 from the melting chamber was below the axis of the row of tuyeres 2 at a depth of 5-15 hole diameters tuyeres 2. When the depth of the edge is less than 5 diameters tuyeres 2 coal loaded into the melting chamber, entrained slag in the recovery chamber and the melting chamber is broken is the rate of carbon/oxygen and heat balance. This results in cooling of the slag and its freezing in the melting zone. In some cases, namely when a significant difference of melting and recovery of materials required by the technical regulations, through tuyeres 2, 3 additionally served as natural gas or other energy sources in the camera 6 or 7. Hot gaseous products of CO, H and others, reaching the top row of torches tuyeres 4, are subjected to oxidation, giving heat to the particulate material (slag, etc. in bubbling fluidised bed layer and the mirror layer of slag in the bath chambers 6 and 7. In the upper part Bartiromo melt in the recovery chamber 7 via boot device 22 is injected solid carbonaceous materials such as coal and, if necessary, the material balance of melt, additional fluxing materials, including sulfidization. Coal is injected in an amount necessary to restore the recoverable metal oxides and thermal compensation costs. The splashing of the melt to accelerate heat and mass transfer and oxidation of the fuel to the required content of carbon monoxide (CO) and hydrogen in the chemical reaction zone in the melt support by supplying oxygen-containing blast through a number of lances 3. In the redox reaction and, if necessary, sulfatirovnie in the recovery of camera obrazets the metal or sulphide phase, droplets which descend to the bottom of the recovery chamber and released from the furnace through the appropriate channel. Slag, depleted in colour and black metal, released through the channel for the release of the slag in the siphon 8. Gases recovery chamber containing CO and H2to save fuel and reduce their toxicity dorogaya, feeding oxygen-containing blast through a number of lances 4. This naturlandia gases from the furnace in the stage preceding the filling of the bath siphon 8 to the channel layer of slag tapping, thanks to the message channel for exhaust gases 9 siphon 8 with the upper area of the recovery chamber of the furnace, its heat to give the elements of the siphon 8 and slag in it. This eliminates the possibility of solidification of the metal and slag in the siphon 8, on the one hand, and on the other, eliminates the possibility of a sharp thermal stresses in the lining materials siphon 8, and the metal structural elements. As the filling of the siphon 8 slag to the level of the channel to release the slag last opened and began producing slag. Then after the supply voltage is in the blocks 16 and 13 by means of block 13 introducing electrode 11 through the sleeve 12 to the inside of the siphon 8. While the end of the electrode 11, the pushing cover the penetration hole of the sleeve 12 normally closed valve (not shown), enters into the internal cavity of the trap 8. After that El is d 11 serves low voltage from the power source 15, and the control for changing the nature (frequency characteristics) and the values of current and voltage, consumable electrode 11, as well as measurements of immersion of the electrode, determine the time point of contact between the electrode 11 with a layer of slag and fix the upper level of the slag in the siphon 8. Then continue the immersion of the electrode by means of the block 13. At the entrance electrode 11 in the area of the interface of the metal and slag layers, the current through the electrode 11 increases sharply to a value close to the value of the short circuit that will be fixed by the block 16, block 13 will stop the vertical movement of the electrode 11. The corresponding fixture block 16 will show the metal level in the siphon. From the condition of energy savings after that, the electrode 11 attach mode "sliding motion" or enter a reciprocating motion of the electrode with experimentally selected frequency and amplitude. If the slag and the metal through the appropriate channels are produced continuously, the metal level in the siphon 8 is supported above the channel release metal with some margin vh. When using the oven usually formed of refractory growths on different parts of the siphon 8. In addition, a separate lining and coating materials may collapse and overlap the lower window of the flow of melt from the chamber 7 into the cavity of the siphon 8 or clogging the channel of metal production. In these cases, using block 13 deviation of the electrode 11 in W is the LCA 12 from the vertical to achieve the formation of an electric arc between the lower end of the electrode 11 and the grounding 20, that allows you to melt refractory education and growths. After accumulation of experimental dependencies between loading materials, recovery time and the rate of change of level of the metal, slag and refractory units in the area periodically raise the level of metal in the bath siphon 8 (for example, a cover or complete closure of the channel of metal production and release of refractory education through the slag channel siphon with subsequent controlled return of the metal level back up to a given technological regulations. After installation, normal or regulated values download threads, the degree of recovery, levels of slag and metal detect in any way the value of the mechanical loss of the metal from the slag stream. If these losses exceed technologically valid value, then for a given value of the metal level in the siphon 8 to the electrode 11, the end of which is installed on the border of the interfacing layers of metal and slag, serves this tension, which will stand the heat between the metal layer and the slag, sufficient to reduce the viscosity of the slag. When this mechanical grip metal superheated slag stream is reduced to a minimum. Gases, intensely eye-catching at the same time, through the channel to exhaust gases 9 are placed under the roof of the furnace and give off their heat to vitaux the m particles Bartiromo slag layer recovery chamber 7. In the modes of use of the electrode 11 to the achievements described here, the positive effects of the electrode is taken out of the siphon 8 with full or partial disconnection from the power source 15. This, in turn, saves energy and reduces the consumption of the electrode material. It should be noted that the presence of the electrode 11 in conjunction with the elements 13, 14, 15 and 16 allows the siphon to Refine the produced metal, matte or slag. The presence of the block 19 as part of the proposed furnace can burn made of fine particles and other flammable substances in the riser pipe 18 to exhaust gases 17, and the combustion products (ash and others) back in the oven. Of heat due to the heat get highly saturated steam in the riser with evaporative cooling. This eliminates not only the possibility of explosion due to accumulation of fine carbonaceous particles in "dead" zones pipes for the exhaust gases, but also allows you to receive high temperature steam for useful use, for example to generate electricity in a steam generator. Note also that the presence of the block 19 with open channels for air flow helps to vapor pressure in the furnace design elements when water is present in the melt in the furnace (temperature 500-1900°C) due to possible breakthroughs cooling caissons. Thus, the set of distinctive features of the proposed furnace helps to ensure long-term operation of the furnace process regulations with minimal mechanical losses of metals; it also increases the safety and reliability of operation of the furnace due to the controllability of the processes of melting; more efficient utilization of exhaust gas heat. 1.
