FIELD: metallurgy.
SUBSTANCE: procedure for production of chemically active metals and reduction of slag consists in supply of reaction charge containing composition of produced metal and metal-reducer into reaction zone and in heating charge for metal reduction. Also reaction charge is supplied into the reaction zone of an internal cavity of a graphite electrode corresponding to an anode. Metal thermal reduction is first made inside the electrode. Further, charge is transferred and at its exit to an end of the electrode into the zone of arcing plasma-chemical and electro-chemical metal reduction is continued forming bath of liquid metal and slag. After that metal is cooled at crystalliser corresponding to a cathode, while slag is tapped into the second crystalliser corresponding to a cathode. Electrolysis of metal-reducer is carried out by means of the second graphite electrode corresponding to the anode. Next metal is supplied to the repeated process of reduction. The device consists of two crystallisers, two electrodes, a case, a mechanical device supplying charge, a hopper and a branch. Notably, the crystallisers correspond to cathodes. Two electrodes correspond to anodes; also the first electrode is made with a central orifice through which charge is transferred to the crystalliser by means of the mechanical device positioned inside the hopper. The second electrode is made solid.
EFFECT: reduced expenditures and increased rate of process and metal purity.
