Abstract

PURPOSE:To prevent width shape defects of a product and to improve the rolling efficiency by edging a slab to obtain a target width in edging just before the final edging and performing the final edging after finishing a sheet thickness to be a target value in the succeeding horizontal rolling. CONSTITUTION:A metal slab 1 is reversibly rolled between rolls 2-4 by installing a horizontal roll 3 (H) stand between stands of vertical rolls 2(V1), 4(V2) having a kaliber. In that case of a draft pass 7 at an edging stage just before the final edging, a target value for which edging amounts are reduced more than end part width shortage amounts DELTAWF, DELTAWT in the length direction is set. After width reducing rolling to obtain a target sheet thickness by the succeeding horizontal rolling 8, an edging 9 at the target value in the final edging is again performed. Hence, a slab whose longitudinal end parts have an enough width is obtained. Therefore, width shape defects of a product are prevented.
