ABSTRACT:
Equipment for the treatment of loads or residues of non-ferrous metals and their alloys include a rotary furnace having a vessel with a sealed door. An electrode is introduced into the rotary furnace and is used to establish a free burning convective electric arc with the load introduced into the furnace or with the furnaces bottom wall. The equipment is assembled over a hinged base which allows elevating or lowering its rotation axis with respect to a horizontal plane.
