ROLLING MILL CONTROL
Rolling mill controls generally are concerned with effecting a change in the roll setting as a function of a change in the rolling pressure. Prior patents that, at least in part, envision such a control are U. S. Pat. No. 2,726,541 that issued to R. B. Sims on Dec. 13, 1955 and No. 3,496,743 that issued to M. D. Stone on Feb. 24, 1970.

Strip Thickness Control of Cold Rolling Mill with Roll ...
12/11/2013 · 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 thickness while PD controller is ...

The development of the theory of metal rolling and its appliion to rolling mill control
The control of rolling is done by a machine, or rolling mill. From a control point of view it is necessary to study the combined behavior of machine and metal deformation to find the variables that may be used to most effectively regulate the process. A typical problem in this area is to control the output thick
