Abstract

PURPOSE:To make fast the speed of response of the titled control, and to improve the quality of product and the yield, by rolling the material giving a necessary temperature distribution to the material at the entry side of the rolling roll, depending on the value of traverse irregularity of the elongation of the rolled material between the different points, computed the result of detection for the shape of the rolled material, and corrected with the detected value of the traverse temperature distribution.
