Abstract

A continuous steel casting method for a casting capacity of more than 1.5 metric tons of steel per minute, wherein a stream of steel is supplied to below the casting level in the mold through a casting tube having lateral openings and at least one additional bottom opening directed vertically downward and having a cross section smaller than the cross section of the casting tube. The angle of inclination of the axes of the lateral openings, in relation to the horizontal, lie within a range of 70 DEG downward to 90 DEG upward. The overall cross section of all of the casting tube openings corresponds to at least the clear cross section of the casting tube. At the place of origin of the stream of steel above the mold inert gas is supplied in a certain amount to the stream of steel over its entire cross section.
