Abstract

Drive loads for a plurality of drives of a mill train for rolling rolling stock with a plurality of rolling stands each being assigned at least one drive, are adjusted essentially to a first set point value on the basis of operation of the mill train in accordance with a first pass sequence. Redistribution of drive loads is improved, by adjusting the drive loads during the rolling to a second set point value different from the first set point value based on operating the mill train in accordance with a second pass sequence different from the first pass sequence, wherein at least during the adjustment of the second set point values a feed rate of the rolling stock into the mill train is adjusted as a function of a discharge rate of the rolling stock which is arranged upstream of the mill train in the direction of mass flow.
