Definitions

  • the present invention relates to a rolling process for a Profile, in particular a flange profile, in a universal roll stand with horizontal rollers and vertical rollers with one vertical roller center, the horizontal rollers accordingly a predetermined horizontal desired nip against each other be placed on a horizontal actual roll gap, whereby the vertical rolls against the horizontal rolls on vertical actual roll gaps be employed. It also affects one corresponding universal roll stand.
  • Such a rolling process and the corresponding one Universal rolling stands are for example from DE 38 34 587 A1 known. It is not mentioned in this document that the Horizontal rolling symmetrical due to the horizontal nominal nip with respect to the vertical center of the roller. But this is common.
  • the method and the roll stand of the prior art work already quite good, but not yet completely satisfactory.
  • the object of the present invention is therefore therein, a rolling process for a profile and a corresponding one To create universal roll stand by means of which Profiles even better, especially with smaller tolerances, are rollable.
  • the task is solved for the rolling process in that the horizontal rollers via hydraulic cylinder units on the Horizontal actual roll gap and the hydraulic cylinder units an additional setpoint is specified on the basis of whose the horizontal rollers in the same direction around the same Amount can be adjusted vertically.
  • Hydraulic cylinder units can also be adjusted under load. It is therefore also possible that the additional setpoint during of rolling the profile is changed.
  • the rolling process delivers particularly good results if that rolled profile is compared with a target profile and the Additional setpoint based on the comparison of the rolled profile is determined with the target profile.
  • the additional setpoint is automatically optimized. Especially in such an automated
  • the control procedure is to change the additional setpoint even during rolling the profile makes sense.
  • a profile 1 in a universal roll stand be rolled.
  • the profile 1 is according to Figure 1 as a symmetrical Double-T profile. But it could, for example also as a rail profile, as an X-beam, as a T-beam or be designed as a different profile.
  • the universal roll stand has horizontal rolls 2, 3 and vertical rolls 4, 5 on.
  • the vertical rollers 4, 5 have vertical Roll centers 6, 7 on.
  • the vertical rollers 4, 5 are there built into the universal mill stand so that its vertical Roll centers 6, 7 are arranged at the same height.
  • Actuators 8 to 11 are assigned to rollers 4 to 7.
  • the Actuators 8 to 11 are hydraulic cylinder units educated.
  • rollers 4 to 7 can be roughly preset via further actuators, not shown, in particular electromechanical actuators. It is crucial, however, that the setting of roll gaps takes place both in the no-load state and under load via the hydraulic cylinder units 8 to 11. If appropriate horizontal or Vertical target roll gaps h * , v1 * , v2 * are thus the horizontal rolls 2, 3 against the horizontal target roll gap h * against each other on a horizontal actual roll gap h. The vertical rolls 4, 5 are set against the horizontal rolls 2, 3 on vertical actual roll gaps v1, v2. The adjustment or adjustment of the rollers 2 to 5 always takes place via the hydraulic cylinder units 8 to 11.
  • the horizontal desired nip h * is predefined for the horizontal rolls 2, 3 or their hydraulic cylinder units 8, 9 at a start time t0.
  • the horizontal rollers 2, 3 and their actuators 8, 9 are also given an additional setpoint o * at this time.
  • the horizontal rollers 2, 3 are adjusted to actual positions x1, x2 with respect to the vertical roller centers 6, 7.
  • the zero line is defined by the vertical roller centers 6, 7, which coincide.
  • the horizontal rolls 2, 3 are adjusted symmetrically with respect to the vertical roll centers 6, 7 due to the horizontal desired nip h * .
  • the horizontal rollers 2, 3 are vertically adjusted in the same direction. This results in a vertical displacement of the horizontal rolls 2, 3 with respect to the vertical roll centers 6, 7 while at the same time maintaining the horizontal actual roll gap h formed by the horizontal rolls 2, 3.
  • the nominal roll gaps h * , v1 * , v2 * and the additional nominal value o * are kept constant while the profile 1 is being rolled.
  • a new additional setpoint o * can be specified at a change time t3 that lies between the run-in time t1 and the run-out time t2. It is also possible to change the nominal roll gaps h * , v1 * , v2 * .
  • a horizontal measuring device 12 is arranged downstream of the horizontal and vertical rollers 2-5.
  • the rolled profile 1 can be detected by means of the profile measuring device 12.
  • the profile measuring device 12 is connected to a profile controller 13 for control purposes.
  • a target profile P * can be fed to the profile controller 13.
  • the profile controller 13 compares the rolled profile 1 with the target profile P * and uses the comparison to determine the additional target value o *.
  • the profile controller 13 is connected to the actuators 8, 9 for the horizontal rolls 2, 3 in terms of control technology. He can therefore directly transmit the additional setpoint o * to the actuators 8, 9.
  • the transmission can be made either continuously or discretely (ie between two profiles 1 to be rolled).
  • the horizontal and vertical rollers 2-5 are preceded by a roller table 14 for the profile 1. Furthermore, the horizontal and vertical rollers 2 - 5 are followed by a flange compression stand 15 for the profile 1.
  • the roller table 14 and the flange compression stand 15 each form a component 14, 15 upstream or downstream of the universal rolling stand.
  • the components 14, 15 are vertically adjustable via actuators 16, 17.
  • the actuators 16, 17 can again be designed as hydraulic cylinder units.
  • the components 14, 15 and their actuators 16, 17 are also supplied with the additional setpoint o * .
  • the components 14, 15 can thus also be adjusted vertically on the basis of the additional setpoint o * .
  • the vertical adjustment of the components 14, 15 can act in the same or opposite direction and can be as large as or smaller than the additional setpoint o * .
  • the roller table 14 can be adjusted in the same direction by the same amount as the horizontal rollers 2, 3, and the flange compression stand 15 in the opposite direction by a part of the additional setpoint o * .
