Abstract
A mold for the continuous casting of steel defines a casting passage having an inlet end for molten steel, an outlet end for a continuously cast steel strand, an upstream portion extending from the inlet end approximately halfway towards the outlet end, and a downstream portion extending from the upstream portion to the outlet end. The upstream portion is formed with a plurality of radially outwardly directed protuberances which are arranged side-by-side circumferentially of the casting passage. The size of the protuberances decreases from the inlet end towards the outlet end in such a manner that the strand is shaped during travel through the upstream portion of the casting passage.
