摘要：<p>A method of improving strip shape during rolling involves introducing at least two intermediate bend rolls (12, 13) (Fig. 1) between adjacent mill stands (10, 11) and adjusting the speeds of the adjacent mill stands so that so as to stretch the strip during the bending. The strip (14) leaving the bend rolls may be made to travel 5% faster than the strip entering the bend rolls by adjustment of mill roll speeds. The method is applicable to both hot and cold rolling. <IMAGE></p>
