  • Preventing undulations when rolling metal strips
    Patent number: 11858021
    Abstract: 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 (?s) 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).
