system combined with positive methods such as absolute AGC, thereby suppressing thickness amplitude of the steadystate portion and reducing topend off gauge length. Further, with a view to automating the avoidance of rolling problems in highload rolling, a new excessive rolling force/ torque avoidance control function has been incorporated.

The novel GMAGC system has been applied successfully in a hot strip mill, the application results show that the thickness control precision is improved significantly, with the novel GMAGC system
Once within specification, AGC optimises the mill speed by adjustment of tension, load or gap. At the end of the coil, AutoSlowdown ensures the product remains in specification for as long as possible and brings the mill to a halt with minimum amount of material left on the coil drum.
Abstract: The rolling mill screw down AGC system sets several subsystems of machinery, electronics, hydraulics, controls in one. Under the action of responding extreme frequency or external disturbances, the non design objective coupling between the subsystems may be excited, and causing the most serious vibration, seriously impact product quality or even cause great destruction.
The invention relates to an automatic gauge control (AGC) selfadaptive control method for a hot rolling mill, wherein the problem, which cannot be solved by an AGC setting model, that thickness control precision of several strip steel heads before changing a specification during a rolling procedure is not high is solved. The technical scheme of the invention is that the AGC selfadaptive
27/06/2008#0183;#32;Abstract: Mill Modulus Control (MMC) is one of important methods on Automatic Gauge Control (AGC) systems of strip rolling mills. It would result in a slower adjusting speed of strip rolling gap to combine the former AGC system and MMC simply without changing the compensating coefficient of rolling efficiency, which was deduced in detail by some inferential reasoning formulas.
By studying the allround mill AGC system of rolling mills,building mathematical models of the system about a hydraulic pressure system,analyzing characteristics of time domain and frequency domain before and after correction in the PI,studying influences on the dynamic properties of all the major factors,and analyzing corresponding improvement measures about the AGC mill hydraulic system.
Converted aluminum rolling mill to lead rolling mill Upgraded PLC, HMI, drives, and AGC Provided AGC system using existing screwdown motors Lithium Mill: single stand / 4 high Designed, built, installed, and commissioned entire mill and control system, both Level 1 and Level 2 systems
As one of the most important functions of the basic automation of the rolling mill, the hydraulic gap control (HGC) is the inner loop of the automatic gauge control (AGC). Therefore, the good dynamic characteristics of the HGC system are very important to the AGC system . The HGC system consists of twoacting hydraulic cylinders per stand and
