Provided herein is a system, apparatus, and method for continuous casting of metal, and more particularly, to a mechanism for controlling the shape of a direct chill casting mold to dynamically control a profile of an ingot cast from the mold during the casting process. Embodiments may provide an apparatus for casting material including: first and second opposing side walls; first and second end walls extending between the first and second side walls, where the first and second opposing side walls and the first and second opposing end walls form a generally rectangular shaped mold cavity. At least one of the first and second opposing side walls may include two or more contact regions, where each of the two or more contact regions may be configured to be displaced relative to a straight line along the side wall.

A casting mold material used in casting a metal material has a composition including 0.3 mass % or more and less than 0.5 mass % of Cr, 0.01 mass % or more and 0.15 mass % or less of Zr, 0.1 mass % or more and less than 2.0 mass % of Al; and a Cu balance including inevitable impurities and has precipitates in a needle shape or precipitates in a plate shape.

A method for manufacturing a continuous casting mold in which cracking and spalling are less likely to occur in a filling laminate. The method includes filling a plurality of concave portions formed on an inner surface of a copper-made mold copper plate or a copper alloy-made mold copper plate used for continuously casting steel at least in a region including a meniscus position of molten steel in a casting process with a metal having a thermal conductivity different from that of the mold copper plate.

The present application discloses a convex lens-shaped narrow face copper plate for continuous casting molds and its utilization method. The narrow face copper plate includes a first hot face and a second hot face. A first connecting line being provided at a joint of the first hot face and the second hot face, and two such first connecting lines being provided. A cross section of the first hot face is a convex arc, and the first hot face extends from an top of the narrow face copper plate to a bottom of the narrow face copper plate, and a height of the first hot face protruding relative to a plane where the two first connecting lines are located gradually decreases from the top of the narrow face copper plate to the bottom of the narrow face copper plate.
