Strip Thickness Control of Cold Rolling Mill with Roll

Strip Thickness Control of Cold Rolling Mill with Roll

Nov 12, 2013 In rolling mill, the accuracy and quality of the strip exit thickness are very important factors. To realize high accuracy in the strip exit thickness, the Automatic Gauge Control AGC system is used. Because of roll eccentricity in backup rolls, the exit thickness deviates periodically. In this paper, we design PI controller in outer loop for the strip exit
