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. A new compensating coefficient that could let the AGC system make a quick response to the entry thickness deviation was put forward, based on studying deeply related control theories and models. With the compensating coefficient of rolling efficiency being reworked, the AGC system got an improvement on quickening its responding speed, and strip thickness precision became better on the production line, too.
