PROBLEM TO BE SOLVED: To make the center of the width of a steel sheet and the center of rolling of a universal rolling mill so as not to generate the deviation in position. SOLUTION: By this method, a slab is roughly rolled with a break down mill 1 and, next, the steel sheet is obtained by performing rolling having a plurality of passes with a universal mill 2 and a horizontal roll mill 3. When the rolling with the horizontal roll mill 3 is performed, the rolling with the horizontal rolls 2a, 2b of the universal mill 2 is not performed. Then, lateral bend is not generated in the rolling with the universal mill group and the steel sheet having a good shape in the longitudinal direction is rolled. COPYRIGHT: (C)2007,JPO&INPIT |
