Improvement and application of Automatic .

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.
