Abstract

PURPOSE:To prevent upper and lower work rolls from being flawed and improve product quality by disposing a pair of upper and lower sleeves contacting the work rolls across the overall length in their axial direction in such a manner as not to move axially. CONSTITUTION:The left end part of a bearing 9' is positioned to the approximate left end part of a plate 19, and the size between the right end part of the bearing 9 and the left end part of the bearing 9' are matched approximately to the width size of the plate 19. The plate 19 is then sandwiched between upper, lower work rolls 5, 5' and is screwed down; at the same time, bending force is acted upon the upper, lower work rolls 5, 5' by roll bending devices 3, and while the bending of the upper, lower work rolls 5, 5' is thus being corrected, the rolling is performed. The rolling force is transmitted to the plate 19 in order of upper, lower stay rolls 16, 16', sleeves 10, 10', and upper, lower work rolls 5, 5'. The sleeves 10, 10' obviate giving dents to the upper, lower work rolls 5, 5', and also prevent the rolled plate 19 from being flawed.
