METHOD FOR HOT-ROLLING WIDE FLANGE SHAPE

摘要

PURPOSE: To improve the accuracy of the right and left flange widths of a wide flange shape manufactured by hot rolling. CONSTITUTION: The right and left flange widths of a base stock before edging rolling are determined, the position in the axial direction of the upper and lower rolls 3A of an edging mill 3 is adjusted so that the difference between the right and left flange widths of the base stock after universal rolling following edging rolling becomes zero based on the difference between the right and left flange widths of the base stock before edging rolling and edging rolling is executed.
