Abstract
Combined with the characteristics of reversible single stand cold 20-roll mill,a set of high precision cold rolling mill rolling thin strips of the AGC integrated control strategy was proposed for the problems encountered in practical applications.The feedforward AGC,feedback AGC,mass flow AGC and gauge compensation AGC during acceleration and deceleration in the gauge control system were analyzed and studied in detail.An improved mass flow AGC algorithm was introduced.The application result indicates that the relative gauge error of product was within ±1%,satisfying the requirement of the production.
