Abstract

In a rolling mill, an open-loop and/or closed-loop control device and a method for adjusting a discharge thickness of rolling stock which passes through a multi-stand mill train, wherein a first section of the rolling stock is rolled to a first discharge thickness, a second section of the rolling stock is rolled to a second discharge thickness which is different from the first discharge thickness. Because a transition from the first discharge thickness to the second discharge thickness takes place at a feed rate of the rolling stock into the mill train which is adjusted as a function of a discharge rate of the rolling stock of a unit which is arranged upstream of the mill train in the direction of mass flow, a method can be made available which runs essentially without reactions for units which are arranged upstream of the mill train in the direction of mass flow.
