In the continuous casting of steel with an open casting stream between a tundish and a downstream mould (1), a multi-phase mixture of liquid inert gas and a particulate substance is introduced as a layer (7) onto the surface (5) of the molten metal in the mould. Casting powder together with the inert gas as the multi-phase mixture is applied directly to the surface of the molten metal during the coating, at a distance from the casting stream (2), via a common line (6). This distance is greater than half the diameter (8) of coating stream. The wave (9) caused by the casting stream prevents the casting powder from being swept into the liquid casting head (3). <IMAGE> |
