摘要

This paper is concerned with the design of an electrohydraulic automatic gage control for a hot strip mill finishing train. The roll force method of gage control is employed wherein a measurement of the total force exerted by the mill upon the strip is used as an in-line variable to adjust the roll opening. Movement of the rolls is accomplished by energizing a hydraulic actuator mechanically connected to a nut which, in turn, is superimposed on the stand screws. With this technique of control, roll opening changes exceeding 60 mils per second were achieved.
