TECHNOGENIOUS RAW MATERIAL PROCESSING ELECTRIC FURNACE Russian patent published in 2004 - IPC

FIELD: non-ferrous metallurgy.

SUBSTANCE: invention relates to designing and operation of ore-smelting electric furnaces operating with dipping of electrodes into melt of material under processing and it can be used in ferrous metallurgy and chemical industry. Proposed electric furnace has body with side walls, charging devices, electrodes assembled into groups, one of which is installed in furnace heart being connected to negative pole of current source, and other group, electrodes of which are arranged in row, is dipped into melt of material under processing and is connected to positive pole of current source. Vertical partitions made of non-conducting material and dipped into melt of raw material under processing are installed between electrodes of different polarity and secured on side walls of furnace. Proposed invention is aimed at increasing reliability of dc electric furnace used for processing technogenious raw material containing heavy and light nonferrous metals-out-of-balance and rebellious polymetallic ores, current and accumulated intermediate products such as slags, slimes, clinkers, etc. with high content of valuable components and secondary raw materials and practically any waste materials with distilling volatile and changing over non-volatile valuable components into bottom phase.

EFFECT: improved reliability of operation at increased yield.
