Abstract

PURPOSE:To manufacture the strip in beautiful shape and accurate siz, by installing a roll bender for adjusting the crown of strip through two rolling passes made up by inner and outer work rolls. CONSTITUTION:The material S, being wound by half around the outer surface of each of inner work rolls 1 and 2, is continuously passed through the 1st rolling pass I, the 2nd rolling pass II and the 3rd rolling pass III successively. In the 1st rolling pass I and the 3rd rolling pass III, the roll crown of outer work rolls 3, 4 is adjusted by roll benders 18, 19 in order to obtain the product in required shape. The strength of roll bending forces F1, F2 is adjusted independently of each other by adjusting the oil pressure to be supplied to the roll benders 18 and 19. For the purpose of giving an increased bending to the outer work rolls 3 and 4, and bending forces F1 F2 are applied to roll chocks by benders 18 and 19 so as to make outer work roll chocks 13, 14 and backup roll chocks 15, 16 attract each other.
