ABSTRACT:
In a process for producing blocks of metals, in particular steels and nickel-base and cobalt-base alloys, by remelting self-consumable electrodes under electrically conductive slag in an atmosphere of controlled composition, the operation of melting down the self-consuming electrode is effected in a space which is gas-tightly delimited by the slag bath surface, the wall of a chill mold and a hood which is disposed on the chill mold, wherein for opening the closed-off space for effecting the electrode-change operation the gas-tight connection between the hood and the chill mold is separated, with the hood raised the residual electrode portion is removed from the melting region and a new electrode is moved into the melting position.
