Before Hydraulic AGC Cylinders became a standard fixture in flat rolling mills, electrical DC motors were used to adjust top rolls for roll gap adjustment. Different systems from Ward Leonard to SCR's controlled bridge rectifiers1 with or without circulating current were used to fasten the response of screw down motor controls.
