Abstract
An ingot mold for the continuous casting of metals. The mold has a mold cavity that is open at opposing ends. The cross-sectional area at the casting pour-in-side is larger than the cross-sectional area of the end from which the billet emerges. To achieve higher casting performance and attain better billet quality via more uniform temperature distribution over the casting cross-section, the mold cavity has multiple conical depressions on an outer cooling surface. These depressions, which are arrayed over at least one area, constitute a region defining elevated heat transfer coefficients. The cooling-side surface in the bath level area of the ingot mold has a roughened structure over part of its surface, the roughened structure tapering in the casting direction.
