Abstract
A die cavity of a casting die, such as for continuously casting billets, blooms and blanks. The die cavity has a cross-section with a partially curved peripheral line, whereby, with the cavity walls cooled, provides improved heat exchange between a forming strand shell and the die cavity wall, thus avoiding solidification defects in the strand shell. The degree of curvature 1/R is reduced at least on part of the curved peripheral line of the corner regions from peripheral lines of the same corner regions, that are successive in the casting direction, and at least over part of the length of the die, in the concave corner regions of the die cavity, in order to control the targeted closure of the gap between the strand shell and the cooled die cavity, or a targeted strand shell deformation.
