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 expansion of the hot finisher to 4 stands, which was Phase I of the upgrade program, has been achieved. Figure 1 shows line layout.
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.
Fundamental study on automatic gauge control (AGC) of reversing cold rolling mill was carried out. The study includes the method of evaluating performance of AGC system and designing a control system according to the results of the study. It was concluded that the response of AGC .
Gaugemeter, or BISRA, AGC, named after the British Iron and Steel Research Association. In practice, different control goal requires different mill modulus in the manufacture process of hot rolling mill [4, 5]. AGC can compensate elastic deformation of the rolling mill to a certain extent when rolling .
