CONTINUOUS CASTING METHOD WITH CONTINUOUS CONTINUOUS CASTING OF MIXTURE OF MOLTEN STEELS IN SAME TUNDISH

摘要

PROBLEM TO BE SOLVED: To provide a continuous casting method with the continuous continuous casting, by which the yield of a component mixture range is improved without developing the defective primary pipe and the defective biting of large inclusions. SOLUTION: In the continuous casting method by connecting the different kinds of molten steels in a same tundish, the component fluctuation range of the molten steels is minimized by using the same tundish without using a joint block 3 between the proceeding kind of steel cast slab 2 and the succeeding kind of steel cast slab to connect the two kinds of molten steels. Thus, the portion to become scrap-down is minimized and the continuous casting is executed without interrupting the continuous continuous casting.
