The invention concerns a mold for a continuous casting system with a shaping mold tube made of a material with high thermal conductivity. To reduce the rate of heat removal at the height of the meniscus that forms within the mold cavity, the exterior of the mold tube is provided with a plating of a material of lower thermal conductivity than that of the mold tube. This results in reduced heat flow with higher temperatures in the meniscus area and in improvement in the surface quality of the cast billet.

Molds for a continuous casting system

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.
