摘要： A rolling control device (10) updates a preset load value Pset based on operation actual results at timings ta to tb. The rolling control device (10) derives a plasticity coefficient Qchk based on operation actual results at timings tb to tc. When the determining that it is necessary to re-update the updated preset load value Pset based on the plasticity coefficient Qchk, the rolling control device (10) updates the preset load value Pset again based on the operation actual results at the timings tb to tc.

摘要： A metal band is first rolled in a front and then in a rear (downstream) roll stand of a multi-stand rolling train. A looper between the roll stands may detect a band tension in the metal band. The band tension is supplied to a first and a second tension controller to determine an application additional target value and a speed additional target value. The second tension controller may only determine a value less than or greater than 0, as the speed additional target value, if the band tension is above or below an upper or lower band tension limit. Otherwise, the speed additional target value may be 0. The first tension controller is also supplied with a target tension that falls between the band tension limits. The application additional target value may be used to act on the rear roll stand.

摘要： The invention relates to a method for controlling a rolling process, in which a metal strip is rolled flat by use of at least one roller. It is known from the prior art that the relative position of a neutral point represents a measure of the instantaneous stability of a rolling process. However, traditional methods for calculating the position of the neutral point do not accurately represent the actual properties of metal and therefore have only limited usefulness for predicting the stability of a rolling process. In order to allow better control of a rolling process for rolling a metal strip with regard to the actual behavior of the metal strip, the invention proposes a new method for calculating the relative position of the neutral point, in which in particular the flat yield stress ke and the hydrostatic pressure pNH at the neutral point are incorporated.

摘要： A rolling train for rolling a strip has a number of rolling stands and a coiler. The rolling stands have work and backing rolls. Data of the strip are fed to a control device of the rolling train which determines individual pass reductions for the rolling stands based on the data. It controls the main rolling stands and the coiler such that the strip is rolled in the main rolling stands according to the individual pass reductions and then coiled up. It determines the individual pass reductions such that they are zero and controls the rolling stand arranged directly upstream of the coiler such that—with respect to this main rolling stand—the tension in the strip on the outlet side is less than on the inlet side, but the strip runs through this rolling stand without undergoing any forming, at least on one side.

摘要： The invention relates to a method and a device for the rolling or winding of strip having an equal thickness over the strip width, in which the tension in a strip length portion limited by rolls, winders, or control, guide or deflecting rollers is measured by means of a measuring roller. In order, in this case, to obtain more accurate measurement values and keep disturbing stresses away from the measuring point, between the measuring roller and an assembly (roll, winder, or control, guide or deflecting roller) causing disturbing stresses in the strip, a partitioning device for absorbing the disturbing stresses is arranged.

摘要： A method and an apparatus for an anticipatory thickness control in foil rolling by using characteristic lines stored in a process control computer of the individual manipulated variables (for example, strip tensions, rolling speeds) for various operating points (conditions of operation) or by using an on-line operating physical computing model, also in combination with a monitor control. The method includes the steps of determining the thickness deviations of the foil at the entry side of the roll stand and of compensating the thickness deviations by an anticipatory thickness control. The apparatus includes a thickness measuring device between the running-off reel and the rolling mill or the roll gap of the roll stand. The thickness measuring device is connected to a superordinated process control computer. Following the thickness measuring device is arranged a tensioning unit which serves to change the travel path of the foil strip between the running-off reel and the roll gap. For example, the tensioning unit elongates the travel path.

摘要： A web tension control system includes a stationary rod and a roller attached to the rod by a flexible coupling. A bearing is attached to the inner surface of the roller. The flexible coupling is attached, at one end, to the rod, and, at a second end to the inner portion of the bearing. The inner portion of the bearing is attached to the flexible coupling. One embodiment enables the roller to pivot about a central location where the bearing is attached to the inner surface of the roller. Another embodiment provides full pivotal freedom for the roller to angularly rotate about a central location through a limited range of angular displacement.

摘要： A casting/rolling installation has a continuous casting machine, a light thickness-reduction rolling mill, a width-reduction rolling mill and a thickness-reduction rolling mill which are arranged downstream of the continuous casting machine. The light thickness-reduction rolling mill is driven with a power lower than that normally required for thickness-reduction rolling. The power needed to compensate for the resultant deficiency is supplied to the light thickness-reduction rolling mill by the thickness-reduction rolling mill through the cast strip. As a result, a longitudinal tension is applied to the cast strip as it passes through the width-reduction rolling mill, thereby preventing the cast strip from buckling and being deformed at the width-reduction rolling mill.
