Abstract
A control device of the rolling mill line controls actuators of a downstream and an upstream roll stand. The control device determines control variables for the actuators of the upstream roll stand while taking into consideration a flatness change to be carried out and additionally taking into consideration a contour change to be carried out and controls the actuators of the upstream roll stand accordingly. The control device determines control variables for the actuators of the downstream roll stand while taking into consideration the contour change to be performed but without taking into consideration the flatness change to be performed and controls the actuators of the downstream roll stand accordingly. The control device outputs the control variables to the actuators of the downstream roll stand with a delay of a transport time, relative to the corresponding control variables for the actuators of the upstream roll stand.
