Abstract
Rolling stock () composed of metal is rolled in rolling stands (to) of a roll train () under the control of a control device. The control device, on the basis of a variable (δQ) (which is characteristic of the change in the cross section with which the rolling stock () is supposed to run out of a rolling stand () of the roll train ()), first determines all provisional manipulated variables (Sb to Se) for the rolling stand () and rolling stands (to) located upstream of the rolling stand (), and uses said provisional manipulated variables to determine final manipulated variables (Sb' to Se′), which influence the cross section with which the rolling stock () runs out of the respective rolling stand (to). The control device determines the provisional manipulated variables (Sb to Sd) for the upstream rolling stands (to) by frequency filtering.
