In rolling mill, the accuracy and quality of the strip exit hickness aret very important factors. To realize high accuracy in the strip exit thickness, the Automatic Gauge Control (AGC) system is used. Because of roll eccen-tricity in backup rolls, the exit thickness deviates periodically. In this paper, we design PI controller in outer loop

Automated gauge control (AGC) system has taken a wide area of the recent studies that deals with hot and cold rolling mill. These studies had concentrated to …

In view of the weak nonlinearity of the AGC cylinder [13] of the screw-down system, the mathematical model of the rolling mill is considered as Duffing equation with a small parameter, ε. When an excitation includes two frequency components effects on a non-linear system, the response with more frequencies generates [14].

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.

control. Cylinder failures can shut a mill down, and cylinders that are not operating properly can adversely impact strip or bar quality. Preventive maintenance, precision repair and accurate testing are the key to ensure AGC cylinder performance is reliable and consistently yields tight product tolerances for rolling precision.
