Abstract

PURPOSE: To improve the dimensional accuracy cheaply as compared with the conventional method, by giving the correction to the shape function with the purpose of removing the dimensional error, etc., due to the previously predictable change in the deflection of the roll, at rolling the product with thickness varying in the longitudinal direction.
CONSTITUTION: The previously predictable dimensional error depending on the change in the deflection of rolls 2a, 2b, and/or the change in the outlet point of rolls 2a, 2b is calculated; a correction for removing this dimensional error is given to the shape function of the taper leaf material T; thus obtained roll gap control function is set at the calculator 1. By this function together with conventional devices like as the shift detector 3 installed at downstream of reducing rolls 2a, 2b, the roll gap measuring instrument 4, the servo-mechanism 5, etc., the screw-down device 6 is controlled. According to this method, the product with thickness varying in the longitudinal direction can be rolled at high dimensional accuracy than the conventional method, without pushing up the installation cost.
