METALLOTHERMAL PROCESS AND CONTINUOUS DRAWING, IN COLD INDUCTION FURNACES, OF METALS OR ALLOYS

摘要

The invention concerns metallothermal process and continuous drawing of a metal product consisting of at least one metal, comprising: a step for melting the metal in a first cold crucible (1) heated by induction where the reduction of said metal oxide or salt is brought about in a reduction medium (8) and where the formed metal decants in a solvent medium (7) for the scoria resulting from reduction to be absorbed; a step for gathering and melting the decanting metal, carried out in a second cold crucible (3) heated by induction and located under the first cold crucible (1), for obtaining a continuous drawing of the metal product. The invention also concerns a device for implementing the method consisting of a first induction crucible with cold furnaces communicating with a second induction crucible with cold furnaces for continuously drawing off the molten metal. The invention is particularly useful for obtaining uranium or an alloy containing uranium.
