Nov 12, 2013· 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 eccentricity in backup rolls, the exit thickness deviates periodically. In this paper, we design PI controller in outer loop

STS AGC Cylinders. AGC Cylinders. Because they automatically provide accurate and consistent product gauge control, sophisticated hydraulic Automatic Gauge Control (AGC) cylinders are critical to the performance of a rolling mill. Cylinders that are not ing properly can adversely impact strip or bar quality, and a cylinder failure can shut

The solution thus required a stabilizing system that brings the rolling mill back into a stable and controllable state. This is possible by actively exerting a damping effect on the powerful rollforce cylinders without hampering the automatic gaugecontrol (AGC) system of the mill.

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)

The application at each roll mill required a set of two LSV''s, one located on either side of the mill. The combination measures strip entry and exit speed for determining elongation or for mass flow calculations. One of the 4High rolling mills is a reversing mill so the strip could be moving in either direction.
