Abstract

A continuous casting mold for casting a billet with a polygonal cross section has side walls delimiting a mold space with a polygonal cross section and the side walls have a center region extending from an open top end to an open bottom or exit end of the mold with a first degree of taper and, at the sides of the center regions, abutting side regions with a lesser degree of taper than the first degree. In order to obtain even growth of the casting shell with low frictional forces, the center region has a degree of taper which is greater than the amount from the billet contraction and the width of the side regions increases as the distance from the exit end of the continuous casting mold decreases.
