Definitions

  • the invention relates to a method for controlling the roll gap profile in strip rolling mills with drive and operator-side hydraulic adjustment devices, by means of which the rolls can be adjusted in a stand in a position-controlled manner.
  • the roll gap profile is influenced by shifting and / or by entangling and / or by correspondingly bending rolls in the roll stand. Such influences and influences by changes in force also cause changes in the position of the rollers.
  • the framework is in a reproducible state e.g. calibrated after a roll change.
  • the actuators used are in a neutral or initial position. Since the lower rolls of a roll stand are supported relatively rigidly on the foundations, but the upper rolls of the roll stand are supported less rigidly on the stand, leaving the starting situation as a result of the described influence on the stand geometry or in the force ratio increases the upper rolls change their position as the lower rollers do. This leads to undesired changes in the roll gap, with the result that the rolls have a different inclination to one another.
  • the axial displacement of one or more rollers changes the center of gravity. This changes the torque determined and compensated for during calibration in relation to the center of the scaffold. The operator must take this resulting inclination Manually change it so that a suitable roll gap profile is created.
  • the invention has for its object to be able to carry out such roll gap changes very quickly without the help of an experienced operator.
  • the associated changes in position or the changes in position caused by the changes are determined in the otherwise unloaded scaffold.
  • the position changes in the position determined for the corresponding changes are used in order to counteract the changes in the position of the position which inevitably occur during rolling.
  • the associated adjustment positions resulting from changes in the stand geometry and / or changes in the force relationships in the stand can be determined by tests before the rolling process, e.g. by recording one drive-side and one operator-side curve of the adjustment changes depending on the scaffold geometry and by recording one drive-side and one operator-side curve of the adjustment change depending on the force relationships.
  • the individual values of this curve are stored in the memory.
  • This subordinate control loop can be used to apply correction values to the actual control loop for the adjustment control, which preclude a change in the roll gap.
