Abstract

PURPOSE:To improve the shape quality of a product slab by reversibly rolling a stock with a rolling speed reduced and a drafting amount increased at the biting end part and a drafting amount reduced at the runout end part and the central part. CONSTITUTION:A horizontal roll 5 is installed between stands of vertical rolling mills 4, 6 and a metal slab 1 is reversibly rolled. In that case of rolling a biting end 2 of the slab 1, rolling is performed by a max. drafting amount DELTAVmax and a rolling speed is reduced. The central part except the biting end 2 and the runout end 3 are rolled by a drafting amount DELTAv obtained by decreasing an allocated marginal draft amount per one pass from the max. drafting amount DELTAVmax. Hence, the biting end 2 bears a heavy draft and the runout end 3 bears a light draft and generation of end irregular shape parts is prevented without increase of the number of rolling passes. Therefore, the shape quality of the product slab 1 is remarkably improved.
