Abstract
PURPOSE: To restrict the sheet camber, and to improve the yield, by obtaining the corrective amount of the rolling reduction from the size of camber of the rolled material measured prior to the final pass, and by performing the final rolling pass.
CONSTITUTION: The size of camber Δc of the rolled material 1 having finished the pass just prior to the final pass is measured by the measuring device 3. Next, this value is inputted to the arithmetic unit 4 which then operates the elongation difference Δεf-1 between the left side and the right side according to the formula I. Besides, the arithmetic unit 6 is previously operated to calculate the roll's deformation, and the level correction contribution Af. Then, the elongation difference Δεf-1 and the level correction contribution Af are inputted to the arithmetic unit 5 which operates the corrective rolling reduction ΔSf* for the final pass according to the formula II. This value is inputted to the draft position controller 8 which then controls the rolling mill 2 so as to perform the final rolling pass for the material 1.
