Abstract:
The invention relates to a method for suppressing the influence of roll eccentricities on the run-out thickness of a rolled stock, which runs through a rolling stand, roll eccentricities being identified by using a process model and taken into consideration in the determination of a correction signal for at least one final control element, preferably a final control element for the adjustment position, of the rolling stand, wherein the measured tensile force upstream of the rolling stand is fed to the process model to identify the roll eccentricities. According to the invention, variations in tensile force are fed back in a targeted manner to reduce the effects of periodic roll eccentricities on the rolled stock, whereas all other sources of variation are eliminated. A process model of the rolling nip and the rolls, preferably based on the observer principle, produces reliable data on the roll eccentricity.
