Abstract

PURPOSE: To roll the slab into various different sizes of breadth, by rolling the sheet with the rolling roll relatively rolling in the longitudinal direction of the sheet material, and by successively applying this rolling work to the sheet in its longitudinal direction.
CONSTITUTION: The rolling roll couples 21-1, 21-2, 21-3, their housings 23-1, 23-2, 23-3, and the shifters 25-1, 25-2, 25-3, for shifting each of rolling roll couples in the direction of breadth of the material 27, are provided in the rolling mill. The broadside rolling work is applied to the material 27, while shifting aforementioned rolling roll group in the arrowed directions Y1, Y2, Y3, by the shifters 25-1, 25-2, 25-3, respectively. Hereupon, the proportion of the rolling reductions given by each of rolling roll couples 21-1, 21-2, 21-3, is suitably selected; hereby, the lateral displacement of the material 27 is prevented, and the efficient, stable rolling work becomes possible.
