ABSTRACT OF THE DISCLOSURE: Method of and apparatus for treating and refining liquid metal alloys by direct current arc heating are disclosed. On at least a part of the melt surface there is performed an electrolysis whereby the melt across a layer of liquid slag- electrolyte is connected as an anode or a cathode, and the connection with the other pole, cathode or anode, is effected by means of one or more direct current arcs. Depending upon the desired direction of the electrolysis process, it is pos- sible to change the polarity of the metal melt or the slag- electrolyte. The apparatus for performing the method com- prises a vessel equipped with a mechanism for pouring, a movable cover and movable electrodes. The centers of the electrodes are disposed symmetrically one to the other in a vertical plane. As a source of direct current there are used two or more rectifiers operating independently.
