Abstract
Proposed herein is a method of controlling the thickness of strip stock being rolled between rolls mounted in the roll stand of a mill. An adjusting force is developed to move the supports of one of the rolls, this force exceeding the rolling force and being directed oppositely thereto. Another force prevents the supports of the rolls from moving towards each other and balances the difference between the adjusting force and the rolling force. The factor of proportionality between the movement of the roll supports and the balancing force is in a definite predetermined ratio with the mill stand stiffness factor. The adjusting force is changed in the course of strip stock deformation to compensate for the roll gap variation in proportion to the rolling force according to the following formula:
