  • Closed loop integrated gauge and crown control for rolling mills
    Patent number: 4118963
    Abstract: In a four-high mill stand separate transducer means are provided for measuring gauge in the bite of the work rolls and for measuring the inclination of work roll axis to the horizontal. Means are provided for generating a gauge command signal proportional to the work gauge and a crown command signal proportional to the desired work roll crown. The gauge and gauge command signals are added algebraically and applied to control the roll pressure producing means in the roll stand, and the crown, crown command and the gauge signals are added algebraically and applied to control the work roll bending means so that changes in the roll bending force do not change gauge, and the gauge and flatness of the rolled product are automatically held constant. A roll crown measuring transducer for high lift mills is also disclosed.
