Hydraulic AGC(Automatic Gauge Control) system.
1. Function: In modern strip rolling mills lines, hydraulic AGC (Automatic Gauge Control) system has replaced the old electric screw-down AGC system. Hydraulic AGC system uses a pair of hydraulic screw-down/up cylinders (one for each side of the mill) to change the gap between the work rolls and the rolls act on the strip by generating a rolling force to control the thickness of the strip and keep the desired flatness of the strip.

Features: The GK series hydraulic AGC (Automatic Gauge Control) system developed by ABLYY is a revolutionary solution for rolling mills. It is widely used in hot strip rolling mills with excellent performance of stability, accuracy, and simplicity. The hydraulic AGC system is based on high performance computers and network technology and powerful software features and realizes all-digital thickness control. Position control and pressure control respectively aimed roll gap and rolling pressure of the roller cylinder constitute a basic control inner loop of AGC system, and it can be up to ¦Ìm class of integrated control accuracy. Thickness control (thickness closed-loop control) aims steel strip thickness at the exit of the mill, which constitutes a comprehensive controlling outer loop of AGC. We realize a variety of AGC controlling models through compensation control of depressive cylinder combined with mill stretch model , material stretch model, rolling speed and tensile setting with timely adjust, then we can control the strip thickness deviation and plate shape of target products. We are the sole supplier in China for all the following systems and services: ¡ô Hardware and software of AGC (automatic gauge control )system; ¡ô Hydraulic servo systems and hydraulic cylinders; ¡ô Roll gap measurement gauge, roll force measurement gauge, shape meter, width measurement gauge; ¡ô Hydraulic AGC (automatic gauge control )system completely made by ABLYY ; ¡ô All soft ware and hard ware are designed manufactured and calibrated by ABLYY. 3.
