Abstract

Continuous metal casting method, especially continuous steel casting method, in which the melt is set in rotation about the strand axis within the continuous casting mold and gas in the gaseous or liquid state is fed onto the bath surface excentrically to the mold axis and at an acute angle to the velocity vector of the rotatory movement. The rotatory movement of the melt is brought about substantially by the thrust of the gas directed at high velocity onto the bath surface. The apparatus for the practice of the method has circumferentially of the mold, at least 2 terminal fittings of gas feed lines, whose discharge orifices are so constructed that a rotatory movement of the melt is brought about substantially by the thrust of the gas directed at high velocity against the bath surface.
