<p>In a continuous metal casting method, especially continuous steel casting method, in which tile melt is set into rotatory movement about the strand axis within a continuous casting mold and gas in the gaseous or liquified state is fed onto the bath surface of the melt eccentrically to the mold axis and at an acute angle to the velocity vector of the rotatory movement, the improvement comprising: setting said melt into said rotatory movement substantially by the thrust of at least two gas streams directed at high velocity onto said bath surface each having a velocity vector in the direction of rotation of the melt. The apparatus for the practice of the method has circumferentially of the mold, at least two terminal fittings or 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.</p> |
