In allusion to 300 Reversible cold mill, the composing and the theory of the auto gauge control system is presented. To meet the characteristic of the 300 reversible cold mill, the PID algorithm With Variable Integral Action is used in position and pressure inner loop control of press down hydraulic cylinder to elevate the response characteristic, and the dynamic press compensating algorithm ...
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 ...
simulator was expanded to the AGC for a singlestand cold rolling mill and the automatic elongation control (AEC) for a skin pass mill, and these applications led to studies of product dimension control (thickness and elongation) for various other sheet rolling mills of the company. As a result of the studies, a technique to automatically identify

Automatic rolling process is a highspeed system which always requires highspeed control and communication capabilities. Meanwhile, it is also a typical complex electromechanical system; distributed control has become the mainstream of computer control system for rolling mill. Generally, the control system adopts the 2level control structure#x2014;basic automation (Level 1) and process ...
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)
on wear is another issue. Stresses from Hertzian pressure in 4high cold mill back up rolls were measured years ago, the results were never published, but of high interest also, maybe later. K. H.

The 20 high rolling mill from ANDRITZ Sundwig is mainly used for cold rolling of metal strip to thinnest final gages and wide range of strip width. The special feature in a 20 high mill is the relation between work roll diameter and barrel length.
Nov 12, 2013· types of Automatic Gauge Control (AGC) methods have been developed for hot or cold mill processes. The British Iron and SteelResearch Association (B1SRA) AGC method based on the gaug meter principle and the feede forward AGC method using the delivery time of the strip have been widely utilized in steel rolling mills [3].
