Abstract

PURPOSE: To correct the quantity of change in the crown on the left and right sides of the rolled material to the desired value, to make efficient the rolling work, and to exactly carry out the shape control for the rolled material, by respectively controlling the bending forces loaded on the journal portions of work rolls of the rolling mill.
