Definitions

  • the invention relates to a control method for rolling a strip in a rolling mill, comprising at least a pair of work rolls, back-up rolls and occasionally intermediate rolls, wherein one of the rolls of a set of working and / or back-up rolls to compensate for an operational asymmetric roll gap and to improve the tape an angle amount corresponding to a swing amount is pivoted relative to the backing roll.
  • the work rolls are subject to both thermal and high mechanical stress. As a result, there is a thermal radial expansion of the rollers, and there is also a wear of the work rolls. Due to different conditions of the stress on the tape top and belt underside, the amount of thermal radial expansion and the wear on top and bottom rollers may be different.
  • the document DE 196 18 712 A1 describes a control method for a rolling stand for rolling a strip consisting of a pair of work rolls, a pair of backup rolls, and a pair of intermediate rolls.
  • the existing regulations for rolling force, reverse bending force and roll displacement are specified target values, which were determined online in a roll stand model with a roll bending model.
  • relationships between the rolling force, the rebound force and the roll displacement on the one hand and a corresponding nip course on the other hand are determined online at interpolation points in the roll bending model.
  • a method for conducting a process is known, which is described as a process example rolling of rolling stock in a rolling mill with work rolls, intermediate rolls and back-up rolls.
  • the output of this process is the flatness of the rolling stock, while the manipulated variables consist of known means for pivoting, bending, axial displacement of the work rolls and / or the intermediate rolls and / or the rolling force.
  • the invention has the object to achieve while avoiding an asymmetric nip an improvement in the tape run, to improve the tape shape and set the same conditions on top and bottom rollers.
  • the shape of the work rolls is not calculated, but measured online and used to determine the pivoting amount and / or the corresponding roll displacement position with the above-mentioned steps.
  • An advantageous embodiment of the invention is characterized in that instead of a pivoting of the set of rollers, the analog effect is realized by using different work roll bending forces of the left and right sides.
  • the online determined pivoting amount or the differential bending force is set before the tap of the tape and changed if necessary over the tape length.
  • An embodiment of the method provides that in order to compensate for unequal rolling conditions in the nip between the upper and lower rolls of a set of work rolls, a calculable amount of a swivel angle ⁇ is set on one of the rolls, preferably on the upper roll.
  • a further embodiment provides that a pivoting amount of a set of rolls, for example, is carried out on a scaffold whose working or intermediate rolls are axially displaced.
  • Another embodiment of the method provides that a pivoting amount of a set of rolls, for example, is carried out on a scaffold, the working or intermediate rolls are not moved.
  • control method according to the invention is characterized by the specified steps and the conversion of the determined wedge shape of the roll gap for the corresponding effective ranges linearly to the distance of the jobs or the storage distance and totaling the amount.
  • a complementary measure to minimize the asymmetry is to shift the top and bottom rollers differently, so that U is not equal to ( ⁇ ) U '. This can be done for several bands of a rolling program or only for selected bands.
  • roller with z. B. further wear, d. H. you set a larger displacement amplitude.
  • the differential shift amount between the two rollers must be set in a predetermined permissible search range in such a way that the asymmetry is minimized, primarily in the band edge region.
  • the control algorithm also takes into account the different elastic behavior at different shift amounts of top and bottom rollers, so that these additional influences, eg. B. be compensated by different bending force levels, on the right and left sides or panning.
  • the contours of the work rolls 1, 1 'in FIG. 1 show in a state for an unloaded scaffold with non-shifted work rolls 1, 1 'an approximately symmetrical thermal expansion. However, the upper work roll 1 has a much more pronounced thermal crown than the lower work roll 1 '.
  • the aim of the measures according to the invention is to reduce or eliminate the conditions of such an asymmetry. If these can not be reduced by the known means, such as different cooling or roller gap lubrication, an automatic pivoting of the roller set is proposed according to the invention in order to compensate for the undesired effect of the asymmetry.
  • the invention optimally solves the problem initially posed.
