Abstract

The disclosure relates to a process for separating non-metallic inclusions from hot liquid metal, in particular from aluminum killed soft steel, in continuous casting plants, wherein the metal supplied into a tundish is guided at least once in upward direction to the surface of the metal sump in said tundish under formation of at least one stream at a speed greater than that of the metal in the tundish prior to its being deflected, whereby a wave is formed at the surface of the metal covered by slag. The metal is guided towards the surface of the metal sump by means of a partition wall having at least one opening from which a canal extends in upward direction to end at a distance of from 3 to 30 cm below the metal sump surface.
