Abstract

A control system and method for concurrently controlling the delivery gage and crown of a workpiece while it is being processed in a rolling mill, preferably in the form of a 4-high rolling mill including a piston and cylinder assembly type of force applicator for adjusting the gap formed between the working rolls under the rolling load. The rolling mill further includes roll bending apparatus whereby bending forces are applied to extended journals of the backup rolls for changing the effective roll crown at the roll gap. The control system provides an automatic control designed to concurrently maintain a relationship between signals generated on the basis of rolling mill measurements to control the force applicator and the roll bending device. This concurrent relationship of signals equates a position change of the force applicator with the algebraic sum of signals representing roll gap changes due to a change in the rolling load and due to a change in the roll bending force, while concurrently the change in roll crown due to a change in roll bending force is equated to a rolling load change. The control system includes additional circuitry for an alternate form of concurrent gage and crown control.
