METHOD FOR CONTINUOUSLY CASTING STEEL

摘要

PROBLEM TO BE SOLVED: To maintain high lubrication in a mold while securing consumption of mold powder even in the case of using the mold powder having high viscosity under condition of high drawing speed of a cast slab. SOLUTION: The inner surface shape of the mold 1 near molten steel surface 12 is formed as a tapered shape widened toward the lower part in the drawing direction of a cast slab. A portion at the lower part in the drawing direction of the cast slab from this tapered portion is used for the mold having the tapered shape that is narrowed toward the lower part in the drawing direction of the cast slab or having no tapered shape, and the mold powder 6 is added to the molten steel surface in this mold to perform the casting.
