Abstract
1,243,828. Automatic control of rolling. FRIED KRUPP G.m.b.H. Oct. 18, 1968 [Oct. 21, 1967], No. 49486/68. Heading G3R. A direct measurement of the gap between mill rolls, made by a measuring device which does not constitute a mechanical connection between the rolls, is compared with a desired value so that any difference is effective through a step function generator and hydraulic actuator to control the roll gap adjustment and thus ensure production of rolled stock of constant thickness. As shown, a measurement of the spacing between work rolls 3, made without contact by a photoelectric or electromagnetic device 6, is compared with a desired value 9 so that any difference operates a step controller 11 to restore the spacing to the desired value by control of hydraulic pre-stressing device 5 acting on the work rolls through back-up rolls 1. Provision of several gap measuring devices across the width of the rolls to control bending of the rolls is referred to. The thickness of the rolled material may also be measured and the above mentioned desired value correspondingly adjusted to ensure a constant thickness of rolled material.
