Abstract
Generally, fire refining of metals is carried out by blowing through a liquid melt thick layer and significantly rarely by mixing a melt stream with a gas. Said methods are low-productive and do not ensure rapid gas access to each melt drop. The inventive method for fire refining of metals in a thermodynamically equilibrium system consists in supplying a thin and wide metal layer to a special chamber provided with an inclined bottom and a receiver. Gases are supplied to the chamber through tuyeres embodied in the front wall thereof and through the bottom and form, together with the supplied melt, a drip-gas fog which is thermodynamically equilibrium by sufficiently heating gases and metals to temperatures which ensure a metal flowing temperature excess in a drip-gas mixture for a whole oxidizing-reducing period. Said method ensures a high productivity by rapid gas access to each melt drop and reduces materials consumption of a device.

The most convenient way to heat the metal is by blowing the metal alloy in the furnace bath with various gases, often in the air. The process is usually divided into two stages. The first is the reduction of the metal alloy by blowing with the oxidizer for a long time. On the other hand - restoration of the converted metal by the owner. Otherwise, the removal of slags, as well as the restoration, as well as after, is carried out. This method is divided into the supply of oxidizing gases for the conversion of the alloy and the internal alloy. The release of the reagent inside the melt is simpler, but much more effective. Gas is supplied either through the side of the furnace - below the level of the melt, or through the submerged bodies that supply gas to the bottom of the bath. This achieves a more intensive stirring, which goes into the market and more intensive delivery of the molecules of the disperser throughout the whole of the alloy. The greater the mixing, the more efficient the separation. There is a non-existent method for the smelting of a liquid melt, which results in a large amount of blowing. Even an increase in emissions does not result in a complete comparison of the oxidizer and the reducing agent with an excess of impurities and is emitted. Especially this is visible on the example of copper. Οgnevοe ρaφiniροvanie vτορichnοy zagρyaznennοy copper not πρivοdiτ κ ποlucheniyu copper - Μ1, προduκτa neοb χ οdimοgο for eleκτροτeχnichesκοy προmyshlennοsτi. After the outbreak of copper, electrical products are produced that increase its capacity. In addition, it is necessary to increase the size of the aggregates for a long time, and with a small amount of productivity. This increases the cost of operating the process. The closest proximity to the proposed method is the fire of distilling the method of pouring the refined copper into the fusion of a caustic soda. Significant and quick stirring of the supplied melt is achieved. This method is not intended to result in the use of a solvent which is inaccessible to the consumer. It is also close to the proposed method of processing aluminum alloys with steams. (УДΚ 621.74: 669.715 Л.L. Kaidek, Α.Β. ρarivsky, Η.S. Ganzha). The main method of this is to blow in the CC4 vapor in a mixture with inert gas through a plasma, the working part is buried in the alloy. Here, high temperatures of dissociation processes are achieved and, due to this, the process is accelerated and deepened. Disposal of this process is a prerequisite for the blowing of the hot melt, as is the case with ordinary metal working processes. Μeτall πρednaznachenngy for ρaφiniροvaniya ποsτavlyaeτsya ρasπlavlennοm in the form of πechi or κοvsha in sπetsialnuyu κameρu ρaφiniροvaniya, ποκazannuyu πa c χ Birmingham. With a continuous process, the metal can be delivered through the mix. From the tank with alloy, the metal is supplied to the recess of the tray - 2. The tray is made wide - for the width of the camera. When paving a metal, having thrown it into the recess of the tray, it implements it and a thin, wide, wide merges into the camera. Synt-3 regulates the thickness of the metal discharge area. Liquid metal, falling from the tray for all its width, consumes gases supplied by the side arrays, arranged in two series in a choke. By regulating the pressure in the side formulas, the metal is regulated in the depth of the chamber, and this can change the duration of the process in the chamber. The middle of the camera is executed with a deviation. Therefore, the supply of gases from industrial facilities, also used in a chronically disposed metal burner, is also available. At the same pressure, a small drop in pressure will result in a slight deviation. The metal, after falling to the back, flows to the slots, where it is eliminated with the formation of slag. The slash after (not shown in the diagram) is screened and removed in the first place. When necessary, in practice, a wall does not reach the bottom. When in the drain tray-8 the metal will only fall off from the bottom, and the slag will be disintegrated, (the wall is not turned off, but it is not visible). Gases in the formations are supplied in the heat before equilibrium of the process equilibrium. If necessary, add jams in the form of litter or alloy. GAS HEATING IS EXISTED THROUGH A RECYCLING SYSTEM. Final heating is produced by the plasma. With this, the gases partially dissociate into ions and become more active. Depending on the metal being disposed, if there is no possibility of combining the processes of oxidation and reduction, two cameras will be required. One for oxidation, the second for the restoration of the metal. When the metal is reduced and its recovery is quicker and where the removal of slag before the recovery does not play a large part, these processes can be mixed together. For this, it is necessary to increase the length of the camera and divide the rows of food modules into packages. Corresponding to the first products is the supply of oxidizing gases with undesirable jams, and in the following, they are also unavoidable jams.

The objective of the invention is the fastest delivery of distributors and exporters to a maximum number of recoverable metals. The main reason for this is the most complete removal of the available impurities from the metal alloy. The main condition for the stability of the proposed process is the thermodynamic equilibrium in the chamber of the angry distillation. Delivered dischargers and solvents should not be heated, but heated, they should be switched off to prevent unnecessary discharging The sum of the heat received with the introduced material and the heat from the oxidation should be no less than the sum of the heat spent during this time. Most preferably, the temperature of the material is not less than the temperature of the melting of the refined metal. Such a temperature balance will allow the mined metal to be mined to the smallest amount of heat and mix it with the supplied gas dischargers and absorbers for a short period of time. Deep gas dispersion with metal droplets will speed up the process of separation a little and significantly increase the absorption of impurities into the slag and freeze. Preferred βα is found with nosobα.
