Abstract

PURPOSE:To improve width adjusting efficiency without consierable equipment investment in hot rolling wherein vertical and horizonal rolls are combined by adjusting the width of the plate byusing vertical rolls engraved with arc-shaped calibers in the bottom of grooves. CONSTITUTION:In broadside rolling of a plate ingot in hot rolling, the width of the plate is adjusted with vertical rolls 3 engraved with arc-shaped calibers in the groove of the bottom thence the ingot is horizontally rolled. The arc-shaped calibers of the rolls 3 are formed to the shape of, for example, about 220mm. thickness T2 of the groove bottom, about 150 deg.C angle range theta2 of the roundness part, about 114mm. radius (r) in the bottom part of the groove, about 15 deg. tapered angle theta3 on the side wall of the calibers and about 250mm. depth D2 of the calibers. Since the peak position of the thickness after the broadside rolling is made apart from the width end of the plate by this broadside rolling; therefore the width returning in the subsdquent horizontal rolling is reduced and the efficiency of the width adjustment is improved.
