Abstract

Procedure that allows a safe operation of the vacuum chambers or furnaces, characterized in that a molten metal bath is placed in the vacuum chamber, the vacuum is made in said chamber in the vicinity of its base and it is periodically ignited near the upper part of the chamber the light combustible gases that come off the molten bath.
