METHOD FOR ADJUSTING A DISCHARGE THICKNESS OF ROLLING STOCK THAT PASSES THROUGH A MULTI-STAND MILL TRAIN, CONTROL AND/OR REGULATION DEVICE AND ROLLING MILL

摘要

The invention relates to a rolling mill, a control and/or regulation device and a method for adjusting a discharge thickness (H3, H3') of rolling stock (G), especially a hot strip, that passes through a multi-stand mill train (2). A first section (G-1) of the rolling stock (G) is rolled to a first discharge thickness (H3) and a second section (G-2) of the rolling stock (G) is rolled to a second discharge thickness (H3') that is different from the first discharge thickness (H3). The transition from the first discharge thickness to the second discharge thickness proceeds at a feed rate (V0) of the rolling stock (G) to the mill train (2) which feed rate is adjusted depending on a discharge rate (Vg) of the rolling stock (G) of a unit (6) that is mounted upstream in the throughput direction of the mill train (2), thereby allowing a method which substantially proceeds without provoking feedback reactions from units that are mounted upstream in the throughput direction of the mill train.
