Abstract

PURPOSE: To reduce the amount of crop, by preliminarily reducing the volume of a crop-forming part of the slab to be rolled.
CONSTITUTION: A slab, to be obtained by the continuous casting work or by the blooming work, is formed into a parallelepiped shaped in which top and bottom ends of the slab are tilted toward the rolling direction by a specified angle θ from the normal against the front and back surface of the slab. The volume of the unsteadily deforming zone at the top and bottom ends of the slab, that is the crop- forming part, is limited within a range about twice thickness of the slab in the rolling direction, so that the amount of crop to be formed at top and bottom ends of the slab is greatly reduced by forming the slab into abovementioned shape.
