ABSTRACT:
A method of correcting the thickness variations of a rolling plate by controlling at least one of the top or bottom backup rolls of a rolling mill. The method further comprises an off-line eccentricity identification method, and an on-line eccentricity compensation method. The off-line eccentricity identification method is utilized for establishing an eccentricity vector which stores the eccentricity values of the top and the bottom backup rolls. The on-line eccentricity compensation method is utilized for generating eccentricity compensation signals using the eccentricity vector established by the foregoing off-line eccentricity identification method, and for transferring the eccentricity compensation signals to an automatic gauge control (AGC) system for compensating the backup roll eccentricities and thus correcting the thickness variations of a rolling plate.
