Furnace for pyrometallurgical reduction of ferrous and non-ferrous metals

摘要

A utility model relates to electrometallurgy, specifically to pyrometallurgical reduction of slags in induction furnaces.;The technical task, the solution of which is directed to the device, is to increase the efficiency of the furnace operation, due to a significant reduction in drainage with the slag of the suitable metal and an increase in the productivity of the furnace by the continuous melting process.;The furnace for pyrometallurgical reduction of slags of ferrous and non-ferrous metals consists of a casing 1 in which a graphite crucible 2 is placed. The crucible 2 on the outside has a winding of the turns of the inductor 3 and a cooling system 4. For drainage of metal, there is provided a bottom hole with a tray 5 equipped with a slide gate 6 On the side surface of the crucible 2, there is a side drain hole with a tray 7 equipped with a slide gate 8. The inductor 3 in the area of ​​the side drain outlet with the tray 7 is made with parallel connection of the turns.;Comparison of the claimed device with known ones allows one to conclude that a new positive effect has been achieved, which is reflected in an increase in the efficiency of the furnace operation due to a separate, multilevel release of metal and slag, exclusion of draining the suitable metal from slag and increasing the productivity of the furnace by a continuous melting process. 2 yl.
