Abstract

PURPOSE: To control the breadth of the strip in good accuracy, by installing a breadth meter in the reversing mill for the purpose of correcting the scatter of breadth of the slab as the blank material, the spread occurring in a rolling pass preceding the broadside rolling pass, and the spread occurring in the broadside rolling pass.
CONSTITUTION: The scatter of breadth of the slab as the blank material, and the spread occurring in the rolling pass preceding the broadside rolling pass, are corrected by using the actually measured value of breadth of strip running out of the final pass of passes preceding the broadside rolling pass, obtained by the breadth meter. The spread caused by the broadside rolling pass for a strip just preceding the present rolled strip is actually measured by the breadth meter and the spread of the present strip is arithmetically forecasted; then, the breadth of the present strip is corrected by using the arithmetically operated value of spread obtained from said values of actually measured spread and forecasted spread. By thus correcting the breadth, the thickness of the strip running out of the broadside rolling pass is controlled, so that the strip in the aimed thickness is manufactured with good accuracy.
