METHOD FOR CONTINUOUSLY CASTING DIFFERENT KINDS OF STEELS

摘要

PROBLEM TO BE SOLVED: To provide a method for continuously casting different kinds of steels with which the yield of molten steel can be improve without charging a separating material into a mold. SOLUTION: A threshold value is arranged in the composition difference between the different kinds of steels, and the separating material is charged between the first and the second molten steels only in the case of exceeding the above threshold value in the composition difference between the first molten steel and the second molten steel differing from mutually the kinds of steels poured into the mold cast mutually before and after times.
