Abstract :
Recently, the accuracy of hot strip gauge is strictly demanded, and the strip thickness becomes the most important quality in hot strip rolling. In order to improve the quality of the hot strip gage and to reduce the strip thickness deviation, the automatic gauge control (AGC) system now is widely used in modern hot strip mills. Mill modulus control (MMC) is one of important methods in AGC system for strip rolling mills. Control theories and models related to MMC were studied deeply in this paper. Its ability to eliminate strip thickness deviation, rolling force noise and roller eccentricity disturbances were simulated respectively based on different virtual mill modulus with MATLAB. As a result, how to get a better control effect was analyzed and confirmed.
