METHOD OF CONTINUOUS CASTING

摘要

PROBLEM TO BE SOLVED: To solve such a problem that inclusions in a cast slab may increase according to casting conditions and conditions for applying an electromagnetic force when both of a movable magnetic field generating device arranged in the upper portion of a casting mold and a stationary magnetic field generating device arranged in the lower portion of the casting mold are used simultaneously aiming at improving the cleanliness of the cast slab. SOLUTION: A stationary magnetic field is applied in the direction of the thickness of the cast slab in the casting mold by means of the stationary magnetic field generating device arranged in the continuous casting mold. In addition, an intermittent flow of molten steel is formed in the vicinity of the surface of a solidified shell in front of the molten steel by means of the movable magnetic field generating device arranged above the stationary magnetic field generating device and in the neighborhood of the position of the surface of the molten steel in the casting mold.
