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
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 ...
Jun 06, 2015 In this article the AGC Automated Gauge Control system, of a hot rolling mill is analyzed and different methods are described to improve its performance. The mill stretch compensation and other disturbances during the rolling process are compensated and a rolling speed dependent, adaptive PI controller is developed to accomplish fine thickness control. The improved system has
One can see in the figure that, while the PC mill has the strongest crown control capacity in all of the width ranges, the HC mill is effective for narrow strips, particularly due to the quick response of the roll benders. Initially, the HC mill was applied to the cold rolling mills, and then to the finishing mill stands of the continuous hot
Modern Rolling Technologies include 6 HI mill or 20 HI mill and Tandom mill. The major benefits offered by these types of mills are, 1 High output. 2 Rolling of very thin gauges. 3 Good control on the shape of the strip flatness of strip. 4 Power requirements of 20 HI mill are lower than other types of mills due to very small size of
The first mill of this type was built for the Kinuura Works of Nippon Metal Company. It had a ZR 21-AN mill section with a very small diameter work roll 65 mm. The net result was that the mill was able to take reductions of over 20 per pass on austenitic stainless steel and to keep the strip shape sufficiently flat to obtain good rolling.
