MOLD FLUX FOR CONTINUOUS CASTING OF STEEL, AND CONTINUOUS CASTING METHOD USING THE MOLD FLUX

摘要

PROBLEM 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.

SOLUTION: In the mold flux for continuous casting of steel, the wetting angleθ(°) at 1,140°C 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)≤θ≤70.
