Operating method for a roll train for rolling rolling stock composed of metal, - wherein the roll train has a plurality of rolling stands (3a to 3f), through which the rolling stock passes successively in a transfer direction (x) that is uniform for the rolling stands (3a to 3f), with the result that the rolling stock is rolled successively in the rolling stands (3a to 3f), - wherein, 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 particular rolling stand of the roll train, a control device of the roll train first of all determines, for this rolling stand and a number of rolling stands (3b to 3d) of the roll train which are arranged upstream of said rolling stand when viewed in the transfer direction (x), a respective provisional manipulated variable (Sb to Se) and, using the respective provisional manipulated variable (Sb to Se), determines a respective final manipulated variable (Sb' to Se'), - wherein the respective final manipulated variable (Sb' to Se') influences the cross section with which the rolling stock runs out of the respective rolling stand (3b to 3e) of the roll train, - wherein the control device activates the rolling stands (3b to 3e) in accordance with the respective final manipulated variable (Sb' to Se'), characterized - in that the control device determines the respective provisional manipulated variable (Sb to Sd) for the upstream rolling stands (3b to 3d) by respective frequency filtering of the characteristic variable (δQ) or of a respective intermediate variable (Zb to Zd) determined from the characteristic variable (δQ), - in that the frequency filtering operations are configured in such a way that the determination of the respective provisional manipulated variable (Sb to Sd) for the upstream rolling stands (3b to 3d) in each case includes only frequency components of the characteristic variable (δQ) which are below a respective limiting frequency (fb to fd), and - in that, in respect of the number of rolling stands (3b to 3d) of the roll train which are upstream of the particular rolling stand when viewed in the transfer direction (x), the limiting frequency (fb to fd) in each case remains the same or increases from rolling stand (3b to 3d) to rolling stand (3b to 3d), and - in that the control device determines the provisional manipulated variable (Se) for the particular rolling stand in such a way that the determination of the provisional manipulated variable (Se) for the particular rolling stand includes at least those frequency components of the characteristic variable (δQ) which are above the limiting frequency (fd) of the rolling stand which is immediately upstream of the particular rolling stand when viewed in the transfer direction (x). -
