ABSTRACT OF THE DISCLOSURE The prevent invention relates to a method of and a device for effecting electroslag remelting processes. While effecting an electroslag remelting process by the proposed method an electrode is dipped into a slag bath. Electric current is passed through the electrode and slag bath, heating the slag to a melting point of said electrode. Upon establishing the molten slag bath and a metal pool said electrode is shielded by lowering on the surface of the molten slag bath a disc with an opening for the passage of said electrode so that the disc will float in the slag without coming in contact with the metal pool. A device for effecting electroslag remelting processes, comprising a base- plate mounting a means for effecting an electroslag remelting pro- cess accommodating a slag bath and an electrode that is dipped thereinto and is encompassed with a protective-shield made as a disc in material whole specific density is lower than that of the slag of said slag bath. Said disc is arranged directly on the surface of the slag bath, overlapping essentially all its sur- face area.
