Abstract

PURPOSE:To make possible the effective control of the tickness accuracy along the breadth of the rolled material, by arranging the inclined roll and the axially movable roll within the rolling mill. CONSTITUTION:Between the backup roll 1 and the work roll 3 in this rolling mill, the roll 2 being connected to the inclining device 14 and being inclinable within the horizontal plane is arranged. A couple of rolls 7, 8, being connected to the axial mover 13 and being movable in equal distance opposite to each other, are contacted with the lower work roll 5. In this constitution, the shape of the rolled material 4 is detected by the shape detector 9, and the shape vector Cd is calculated by the operator 10. On the other hand, the rolling condition is produced from the setter 15, and the corrector vectors C1, C2, at this moment are calculated by the operator 12. Then, the corrective amount (a), (b), are calculated from these Cd, C1, C2, by the computer 11; and (a) is inputted to the inclining device 14, and (b) is inputted to the axial mover 13. According to this method, even the composite stretch can be corrected.
