Mold for continuous casting of steel and method for continuous casting of steel

摘要

PROBLEM TO BE SOLVED: To easily perform uniform heat removal from a solidified shell in a casting direction and a circumferential direction even during high speed casting. A steel continuous casting mold includes a copper alloy plate (11) in which cooling water channels (13, 14) are formed, and a backup plate attached to the plate (11) so as to cover the cooling water channels (13, 14). Have. The cooling water passage 14 in the lower portion of the plate 11 is composed of a plurality of grooves, each of which has a vertically long shape extending in the casting direction in the continuous casting process. The cooling water passage 13 in the upper part of the plate 11 is formed by a groove which communicates with the cooling water passage 14 in the lower part and extends in the casting direction and extends in the circumferential direction orthogonal to the casting direction.
