Abstract

PURPOSE: To minimize unevenness in toughness of non-tempered, thick high-tensile steel plate in the direction of its thickness, by rolling a billet of a particular composition, after heating the same in the manner that temperature at the center is more than 30°C lower than that on the surface, so as to compensate temperature difference at the center and surface of the billet at the time of rollingprocess.
