Mold flux for continuous casting of steel and continuous casting method using the mold flux

摘要

PPROBLEM TO BE SOLVED: To provide a mold flux for continuous casting of steel capable of realizing the consistent high-speed casting by consistently promoting solidification in a mold. PSOLUTION: In the mold flux for continuous casting of steel, the wetting angle () at 1,140C of a molten flux with respect to a surface material of a mold is a function of the crystallization temperature Tcs(C) of the flux, and expressed by inequalities : 0.12(Tcs-800)70.
