METHOD OF CASTING CONTINUOUS SLAB

摘要

When a slab is drawn while a mold formed of a long wall and a short one is vertically vibrated in the process of vertical type continuous casting, said long side wall is moved away from the slab with a hydraulic cylinder (4) actuated in a time zone in which large frictional force acts upon the slab. On the contrary, in a time zone in which large frictional force does not act on the slab, the long side wall having been kept away from the slab is brought closer thereto. In this way, by moving the long side wall away from or closer to the slab repeatedly, a depth of oscillation mark is reduced so that a slab with less segregation at the valley of oscillation mark may be obtained.
