The invention relates to metallurgy, in particular to a device for the continuous processing of oxidized Nickel ores, slag and dust. Currently, these types of metallurgical raw materials processed in shaft kilns. The shaft furnace is a rectangular tank - mine, in which top load Kuskovo oxidized ore, fluxes and coke. In the lower part of the side walls have openings for supplying air into the layer of solid preheated coke. The products of combustion of coke is heated and melted charge, which flows down and out of the furnace through the hole located at the bottom. External sump melt into slag and matte or ferronickel. Disadvantages mine smelting are complex and expensive preparation of the mixture to heat (briquetting, balling, and agglomeration), use as fuel only lumpy expensive coke; removal of dust from the exhaust gases exceeds 10% by weight of the charged metal and the emissions of more than 50% of the sulfur contained in sulfidization used to get the matte. All this taken together makes mine smelting environmentally unsound and economically unprofitable. Known liquid-phase furnace for continuous melting of materials containing non-ferrous and ferrous metals (RF patent No. 2242687 on application No. 2003111724 from 22.04.2003, - the number is). Analog has a rectangular bottom and extending in the upper part of the caisson shaft with lances, transverse partitions dividing the furnace into chambers oxidative melting of charge and recovery of oxides of the slag, stage furnace hearth, a siphon for the production of slag, the channel for the release of metal or matte, boreholes for emergency release melts, internal siphon for overflow of liquid slag from the camera oxidative melting in the upper part of the chamber recovery of oxides of the slag, the ducts for the exhaust gases from the camera device to download content. The disadvantage of analogue is that during melting of solid materials on matte or ferronickel produced in the melting chamber or loaded into this camera the melt (for example, hot slag from the shaft furnace) is sent to the window transverse partitions in a thin layer and freezes, blocking the window for flow of melt through the intermediate siphon in the recovery chamber. This in turn leads to the filling of the melting chamber to the upper edges of the transverse partitions and the coal loaded into the melting chamber, entrained slag in the camera repair, thereby causing a disturbance in the melting chamber of the ratio carbon/oxygen and heat balance of the specified process regulations. As a result of this occurs periodically cooling was going and its freezing in the melting zone with the termination of the heat. Industrial testing and use of this furnace ("Black metal", "Nonferrous metals", s-94, 2005, special edition) also showed that is possible to operate the furnace at a solidification of the melt in the window overflow, but when this takes place: the uncontrolled transfer of coal from the melting chamber through the upper edge of the transverse partition in recovery, a considerable shift of the horizontal forces acting on the wall (possibly the destruction of the walls and accelerated wear of the cooling copper caissons forming the upper edge of the transverse septum, followed by the possible explosion due to breakthrough of water from these caissons in the melt). In addition, when testing 2 zone Vanyukov furnace (analog) in industrial conditions were identified another significant disadvantage is that the lining in the lower zones of the walls of the furnace under the influence of thermal deformation forces periodically barred from carrying metal wall and falls to the inside of the furnace, thereby disrupting the efficiency of the furnace. However, these analogues have a common drawback-the freezing of the melt in the separation siphon with a gas exhaust pipe. This disadvantage is particularly reduces the reliability of the operation of the furnace when working with refractory slag and increases the loss of metals from slag. Known furnace for continuous melting with lipidrich materials in the liquid bath, containing melting and recovery zone, separated by a water-cooled baffle with lower flow. In the recovery chamber of this 2-zone furnace installed electrodes, the formation area of the arc which is served by natural gas (the magazine "Nonferrous metals" No. 3, p. 24, 2003 - prototype). The disadvantage of this prototype of the proposed Vanyukov furnace is that the lower the flow or window for flow of melt from one area to another quickly clogged due to cooling of the walls of the box, and the presence of electrodes in the bath with connecting zones and metal (copper) elements of design, through the molten metal, creates a great danger to the service personnel and provides greater current leakage through the reduced metal compounds (Stein or ferronickel). For this reason, this oven has not found its industrial applications. The drawing shows the proposed furnace and its longitudinal section. The furnace contains a caisson shaft with upper and lower tuyeres (not shown) rows, melting and oxidizing 1 and recovery 2 chambers separated by a partition 3 with window for flow of melt and lance for flow control peretekaemosti melt (not shown), inclined or stepped furnace hearth, a siphon for the release of the slag 4, the siphon 4 contains the electrodes or heaters 5, the lower ends of which RA is placed in the zone boundary between the slag and metal melts the channel for the release of metal or matte, the holes for the emergency release of the melts, the window with lance for overflow of liquid slag from the camera oxidative melting into the camera recovery of oxides of the slag, the ducts for the exhaust gases from the chamber recovery, flue for venting flue gases from cameras and siphon cut to release the slag from the camera. The technical effect of the use of the distinctive features of the proposed furnace is that the presence of electrodes 5 (or heaters), or lower teplovidelyaushaya ends of which are located in the zone section of the metal and the slag melt, eliminates the possibility of formation of wall accretions in the siphon 4, as well as to reduce losses of metals with waste slag. The reason is that the electric heating with virtually no mixing of the melt quite easily allows you to change or to adjust the viscosity of any shlakometallicheskih, including, and only the slag melt in the zone section of the metal and slag phases of the bath in the siphon. It should also be noted that the volume of the siphon 4 tens (hundreds of) times smaller than the volume of the recovery chamber 2. In this regard, the power transformer is also less than hundreds of times compared to the power transformer installed in the recovery chamber 2 (prototype), i.e. to maintain the required t is kuciste slag melt in the siphon 4 is sufficient in hundreds or ten times less heat. Because the siphon 4 is only necessary to calm or eliminate as much as possible the mixing of slag and metal, you do not need to submit to siphon gas coolant, and is enough to drain only a small amount of gas release from the slag layer. All this together allows the process with the lowest heat loss, without overgrowing the walls of the siphon outlet and increase the safety of operation of the furnace. The oven works as follows. Ore flux additives and solid fuel load through the arched openings on the surface Bartiromo blown slag melt in the camera 1 of oxidative melting. The splashing of the melt and the oxidation of the carbonaceous fuel is carried out by supplying the oxygenated melt blown through tuyeres in the side walls of the furnace 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 at the bottom edge of the wall 3, through her window in the bottom edge flows into the camera recovery 2. In camera recovery of oxides of the slag through the loading device 16 in the upper part Bartiromo melt in stravitelne camera injected solid carbonaceous materials such as coal, and if you need material balance additional melting 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. In the reduction reactions and if necessary sulfatirovnie, camera recovery is formed of metal or sulfide phase, droplets which fall to the bottom of the camera recovery and release from the furnace through the channel for the release of matte or Ferroalloy. Slag, depleted for non-ferrous and iron, are produced through the window release the dump slag in the siphon 4. Gases camera recovery containing CO and H2to save fuel and reduce their toxicity dorogaya, feeding oxygen-containing blast through tuyeres located in the upper zone of the furnace. After post-combustion gases is removed from the oven for cleaning dust and waste heat through the flue. From the melt in the chamber 2 as metal recovery last accumulate on the furnace hearth furnace and sent to a window to release matte or ferronickel, and the slag is a fine metal particles pass into the siphon 4. In the siphon 4 when soothing layer of slag melt the main part of the metal particles fall to the bottom of the furnace, and a portion (up (0,01÷0,20)% of total weight) is fond of otvajnym slag. Because the section of the slag and the metal layer of the melt there is a heat source which does not cause intense mixing and sparging of the melt, the metal losses can be reduced due to thermal regulation of the viscosity of the slag to (0,01÷0,12)% of their total weight. At the same time exclude the possibility of stopping the furnace due to the solidification of the slag melt in the siphon 4. 1. Liquid-phase furnace for the smelting of materials containing non-ferrous and ferrous metals, including rectangular with a lined bottom walls and extending in the upper part of the caisson shaft with lances of the lower and upper rows, separated by a transverse partition into melting and recovery of the camera, interconnected through the window for flow of melt in the lower zone of the transverse partitions, the furnace hearth stepped or inclined, the siphon with a hole for the release of the slag and the electrode immersed in the melt, characterized in that the electrodes are located in the siphon for the production of slag, fuel ends of which are located at the interface of the slag and metal phases of the melt in the siphon. 2. Liquid-phase furnace according to claim 1, characterized in that the eat siphon more than ten times smaller than the volume of the recovery chamber.
