摘要： A control device (3b) for a roll stand (1). During rolling of a metal strip (2) in the roll stand (1), the device receives measurement data (M) for a lateral position (y) of the metal strip (2) on the inlet side and/or outlet side of the roll stand (1). Taking into account parameters (P) of the stand regulator (3a) on the basis of the deviation in the lateral position (y) from a target position (y*), a stand regulator (3a) of the control device (3b) determines a tilt value (δs) for the roll stand (1) and controls the roll stand (1) accordingly. The control device (3b) determines at least one variable (V1, V2, Q1, Q2) from which it is derived, for both strip edges (7, 8) of the metal strip (2), whether the metal strip (2) forms an undulation (9) in the region of the particular strip edge (7, 8). As soon as the metal strip (2) forms an undulation (9) in the region of one of the strip edges (7, 8), the control device (3b) varies at least one of the parameters (P) of the stand regulator (3a), such that the stand regulator (3a) determines the tilt value (δs), starting from the variation in the at least one parameter (P), and taking into account the changed parameter (P).

摘要： A rolling line for rolling a flat rolling material (2) includes a number of roll stands (1). Prior to the rolling, a control system (3) receives actual variables (I) of the material (2) before the rolling and target variables (Z) after the rolling. The control system (3) determines desired control variables (S*) for the roll stands (1), based on the actual (I) and target variables (Z), in combination with a description (B) of the rolling line, using a model (10) of the rolling line. The control system (3) determines the desired values (S*) such that expected variables (E1) for the material (2) after its rolling are aligned as far as possible with the target variables (Z). The control system (3) transfers the desired values (S*) to the roll stands (1) such that the material (2) is rolled according to the transferred desired values (S*). The target variables (Z) comprise at least one freely selectable, discrete characteristic variable (K1 to K5, K2′ to K4′, K2″ to K4″) defining the contour (K) of the flat rolling material (2).

摘要： A plurality of flat metal items to be rolled (3) are fed to a plurality of rolling stands (1, 2) of a rolling installation, one after the other over a feed path (4). The items (3) are rolled by the rolling stands (1, 2) past which they are fed. In the rolling stands (1, 2), the flat item to be rolled (3) is first rough-rolled in at least one roughing pass with a wedge-type roll gap adjustment (ds) and then finish-rolled in finishing passes. After the finish-rolling of the flat item, a thickness taper (dd) that is present in the respective finish-rolled flat item is recorded by measuring instruments. The thickness taper (dd) is compared with a target taper (dZ). On the basis of a deviation of the thickness taper (dd) from the target taper (dZ) and the wedge-type roll gap adjustment (ds), a new wedge-type roll gap adjustment (ds) is determined for the at least one roughing pass. The wedge-type roll gap adjustment (ds) for the at least one roughing pass for the next flat item to be rolled (3) is set to correspond to the newly determined value of the wedge-type roll gap adjustment (ds), so that the next flat item to be rolled (3) is rough-rolled in the at least one roughing pass with the newly determined value of the wedge-type roll gap adjustment (ds).
