ABSTRACT:
A device for the separation of slag insuring its retention in a tapping converter such as used in the steel industry consists of a closure having a specific gravity lower than that of the steel produced in the converter but higher than that of the slag provided with an elongated depending hexahedron shaped extension that tapers downwardly to a blunt end and acts as a vortex inhibitor within the swirl of molten metal occuring during the tapping of the metal to avoid formation of a suction funnel which typically draws the slag layer into a stream of metal being tapped.
