ABSTRACT:
A method of controlling one stand of a mill for rolling strip material, the mill having upper and lower back-up rolls and a pair of work rolls disposed between the back-up rolls, first and second screw means for respectively controlling movement of the ends of one of the back-up rolls and first and second jack means for respectively applying forces to each of the ends of the work rolls and a shape sensor having outputs from which the stress distribution across the width of the rolled strip is determined, comprising analyzing the effect upon the shape of the strip of the operation of the screw means and the jack means and deriving mathematical expressions, each including a control parameter, respectively representative of such operations determining the difference between said stress distribution and a desired stress distribution and obtaining a correction of stress distribution characterized by separately analyzing the effect upon the shape of the strip of the operation of each screw means and each jack means and deriving four mathematical expressions each including a control parameter respectively representative of such operations, determining a single error distribution E (x) as the difference between said stress distribution and a desired stress distribution, obtaining a single correction of stress distribution C (x) by determining an optimum value for each of said control parameters such that a functional of the distribution E (x)-C (x) is minimized and separately controlling each of said screws and jacks in accordance with said control parameters.
