Abstract: During stabilization of a metal band (1) on a roller path (2), the band (1) is to be only minimally cooled via the stabilisation. A device for that includes multiple protective runners (3), each oriented in the conveyor direction (R), for guiding the band (1), wherein the protective runners (3) are arranged above the roller path (2) and the protective runners (3) are at a distance from one another in a width direction (B) of the band (1). Multiple rows (4) of nozzles are arranged in the conveyor direction (R) or in the width direction (B) of the band. Each row (4) of nozzles includes multiple nozzles (5). The nozzles (5) are set back in relation to an underside of the protective runners (3), such that an arched band (1) cannot come into contact with the nozzles (5). A compressed air supply (6) and a network of tubes or pipelines (7) supply the nozzles (5) with compressed air, wherein the nozzles (5) apply compressed air to the upper side of the band (1) in order to stabilize the movement of the band (1) on the roller path (2).

Abstract: In a normal operation of a roll stand (e.g. 4) of a roll train, working rolls (10) of the roll stand (4) are adjusted to a roll gap (s4) by adjusting a control element position (p4) of a control element (14) of the roll stand (4), such that the working rolls (10) roll the metal band (5). To determine the control element position (p4) to be adjusted, a calibration value (sC4) of the respective roll stand (4), further status parameters (P4) of the roll stand (4) and a target roll gap (s4*) are specified to a model (15) of the roll stand (4). The model (15) determines the control element position (p4) to be adjusted therefrom. In the calibration operation, a control element position (p4) is initially adjusted such that the metal band (5) passes through the roll stand (4) without being rolled. The control element position (p4) is varied such that the working rolls (10) roll the metal band (5). A thickness (d) of the metal band (5) is detected by a downstream thickness-measuring device (9). The thickness (d), further status parameters (P4) and the control element position (p4) are supplied to the model (15), which determines the calibration value (sC4) of the respective roll stand (4) therefrom. Subsequently, normal operation is resumed and the previously determined calibration value (sC4) is used to determine control element positions (p4) to be adjusted as the calibration value (sC4) of the respective roll stand (4).
