ABSTRACT:
A machine in which there is provided a mold mounted on a base plate, a main electrode and an additional consumable electrode and a power supply source connected to the additional electrode and coupled by means of a switch alternately either with the main electrode or with the mold. To effect the remelting process in the above machine, the additional electrode, insulated from the mold, is introduced into the lower portion of the mold melting space, after which a part of the mold melting space is filled with molten slag, the power supply source is connected to the mold and a metal bath is established on the additional electrode; then the main electrode is introduced into the slag bath, the power supply source is disconnected from the mold and connected to the main electrode and melting continues until a casting is melted.
