摘要： There is provided a mill computer control system for automatically controlling the position of the individual drives in accordance with at least one predetermined equation so as to produce variable profile forms of the roll gap. Crown forms and tapered forms are generated by the computer in response to single keystroke commands on the keyboard. The drives may be adjusted simultaneously or individually. Individual adjustments may be made which are preserved during changes in the crown form or the tapered form.

摘要： A flatness control system includes a work stand of a finishing line, a plurality of actuators, a flatness measuring device, and a controller. The work stand includes a pair of vertically aligned work rolls. A first work roll of the pair of work rolls includes a plurality of flatness control zones configured to apply a localized pressure to a corresponding region on a substrate. Each actuator corresponds with a one of the plurality of flatness control zones. The flatness measuring device is configured to measure an actual flatness profile of the substrate. The controller is configured to adjust the plurality of actuators such that the localized pressures modify the actual flatness profile to achieve the desired flatness profile at the exit of the stand. The thickness and a length of the substrate remain substantially constant when the substrate exits the work stand.

摘要： A compensation method of an asymmetric strip shape of a strip rolling mill, for compensating the asymmetric strip shape of a strip caused in a machining process of the strip rolling mill in the prior art. The compensation method is realized by generating a non-linear asymmetric no-load roll-shaped profile curve through polishing an upper working roll and a lower working roll of a rolling mill and forming a non-linear asymmetric no-load roll gap between a transmission side and a working side of the upper and lower working rolls. The strip rolling mill in the prior art refers to a presently commonly used two-roll rolling mill driven by the transmission side of the working roll, a four-roll rolling mill equipped with a support roll and a multi-roll rolling mill equipped with a middle roll.

摘要： The crown on a steel strip in a rolling mill is controlled by a continuous rotational adjustment of an arbor in response to a control signal representing the current crown profile or deviation therefrom, the arbor being equipped with a series of eccentric rings fixed thereto, bearings surrounding the rings, and a continuous or segmented sleeve around the rings. Where the sleeve is segmented, use of an intermediate roll is suggested.

摘要： The invention relates to a control system for setting the crown and/or steer on the rolls of a cluster mill such that the adjustment collars are all driven together but substantially in the desired final ratio to one another throughout the movement. The control system derives a separate control signal for driving each eccentric collar. The circuits for deriving the control signals include means for deriving from crown and steer magnitude signals, a series of crown and steer datum signals, one for each collar, which are proportional to the respective magnitude signals in selected ratios, the crown ratios being preselectable by a selection means and means for progressively increasing the magnitude signals from zero to the desired value.

摘要： Systems and methods of applying a texture on a substrate include applying a texture to the substrate with a work stand of a coil-to-coil process. The work stand includes an upper work roll and a lower work roll vertically aligned with the upper work roll. At least one of the upper work roll and the lower work roll includes the texture. Applying the texture includes applying, by the upper work roll and a lower work roll, a work roll pressure on an upper surface and a lower surface of the substrate. The method further includes adjusting a contact pressure parameter of the work stand such that the work stand provides a desired contact pressure distribution across the width of the substrate and a desired thickness profile of the edges of the substrate while an overall thickness of the substrate remains substantially constant.

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).
