5. Structural characteristics of rolling mill. 5.1 The frame with a whole casting has a large rigidity and the rolling force is radiated on the various sections of the frame. 5.2 The work roll has a small diameter and a high rate of 60%. Some materials do not need to be annealed, so they can be rolled into thin strips.

maximum rolling speed of a cold or foil mill, 8 meters of strip is produced. It is easy to see why Automatic Gauge Control (AGC) is an essential component of modern rolling mills. Comprehensive AGC algorithms incorporate readings from dozens of sensors around the mill. Some of the key AGC input parameters are speed and tension. (See Figure 1)

1.Brief Introduction. This 1450mm 20 Hi Reversible Cold Rolling Mill was designed to roll 1.0~3.0mm plain carbon steel, low alloy steel and 200, 300,400 series. stainless steel board into 0.2-1.2mm thick as clients'requirement. The model has flexible rolling process, and it can adapt to changing raw materials.
Honeywell's Automatic Gauge Control (AGC) and Hydraulic Gap Control (HGC), incorporated with the MetalsMaster gauging system, enable mills to deliver the right gauge thickness with the least product variation. It also offers Target Adaptive control to increase yield, improve product quality and reduce scrap.
Menghui and his colleagues in 2007 in research about control in hydraulic AGC of cold rolling mill used the cascade predictive control by the combination of PID control for the HAGC and dynamic matrix control for the inner loop of the screw-down servo system. This method can hardly solve the problem of gaining the step response of the whole HAGC.

trol (AGC) methods have been developed for cold mill processes. On the basis of a linearized model of the rolling mill system, in 1996, Hwang and his colleagues [1] propose a thickness controller using an internal mod-el control (IMC) structure which effectively rejects peri-odic disturbances. In 2002, the multivariable AGC is designed using ...

Mass Flow, Automatic Gauge Control (AGC) is a technique used for many years to control strip thickness in Tandem Cold Rolling Mills. It enables tighter control of thickness by providing faster and more accurate control of the roll gap. Utilizing Mass Flow AGC control techniques permit operations to achieve specified thick-
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 ...
