Abstract

A procedure and device for purification: steel in a continuous casting plant, for which the liquid steel is allowed to flow into an intermediate container and from this, through one or more outlet pipes, to a water-cooled chill, from which the cast bar is continuously extracted in a solidified state, characterized in that in the immediate vicinity of the outlet or outlets of the intermediate container, it is blown under pressure, from below through the melt, transversely with respect to in the direction of the flow of the steel, a regular scrubbing gas, preferably an inert gas, such as nitrogen or argon, to form a veil or curtain of rising gas bubbles.
