Definitions

  • the invention relates to a method and a rolling line for improving the Ausfädelns a metal strip whose rolling strip end expires at rolling speed from a respectively last yielding mill of a multi-stand rolling mill, wherein during rolling between two successive stands for stabilizing the strip tension is adjusted ,
  • the rolling speed is adjusted so that a required final rolling temperature of the metal strip, in particular steel strip, is achieved.
  • Endwalztemperaturen must be complied with in order to achieve the desired metallurgical properties.
  • a reduction in the rolling speed is undesirable even at the end of the tape. Threading out the metal strip at rolling speed, however, is problematic, especially at high rolling speeds and thin end thicknesses.
  • the strip tension set between the rolling stands is a decisive factor for stabilizing the strip run.
  • the strip tension is reduced shortly before or at the latest with the unthreading from the rolling stand.
  • the rolled strip end is then drawn without tension into the next mill stand.
  • the tape is unstable and minor disturbances or deviations can lead to "bleeding" of the rolled strip end in the nip.
  • the metal strip runs out of the center of the frame, generating differential rolling forces and skewing the roll gap, which in turn accelerates bleeding.
  • causes for this process can be a non-parallel roll gap, temperature differences across the bandwidth, a thickness wedge over the belt width or belt hardness differences.
  • the invention has for its object to consider the unthreading of the rolled strip end at each momentarily resulting last rolling stand of a rolling train as an independent process step and to evaluate the setting of rolling forces on both sides of the rolling stand in a timely manner.
  • the stated object is achieved by a method according to claim 1 and a rolling train according to claim 2.
  • the method provides that, shortly before composing the rolled strip end from a stand, the differential rolling forces generated between the drive side and the operator side are measured separately for each rolling mill, from which the swivel value and pivoting direction of the differential rolling force are derived to form a correction value for the setting of the rolls and the employment is corrected.
  • the advantage is that the initial situation is improved before the threading out and a bleeding of the rolled strip end is largely avoided.
  • the direction and the value of the differential rolling force are determined for this phase and thus a "swivel value" is calculated for the metal strip.
  • the results of the respective measuring step are utilized adaptively from metal roll strip to metal roll strip and the results of the respective measuring step are adaptively utilized from metal roll strip to metal roll strip.
  • One application is that the measurement result for the helmsman in the control center is displayed and the helmsman performs the correction manually during the rolling process.
  • the application according to the invention is achieved by forming an average value of the differential rolling force between the drive side and the operator side after the rolling strip end has been taken out for a selected strip length and utilized in the following metal strip.
  • a rolling mill for hot rolling a metal strip In particular, a thin steel strip is provided with a plurality of rolling mill stands having their work rolls and backup rolls respectively driven on the drive side for maintaining a strip train for stabilizing the strip run and a high rolling speed, and measuring devices for measuring the rolling force on the drive side and the operator side, respectively are provided.
  • the stated object is achieved according to the invention in that the rolling forces on the drive side and on the operator side by force gauges shortly before leaving the rolled strip end are determined as Differenzwalzkraft, wherein an evaluation unit for the differential rolling force of the metal strip end and a computer unit for the calculation of a so-called swivel value for the adjustment of the rolls during the passage of the metal strip end are provided.
  • the advantages here are also those that have already been shown for the process.
  • the force measuring devices for the differential rolling force of the metal strip end consist of load cells, which are each arranged below the lower support roller.
  • the inventive design of the measuring devices is designed to the effect that is connected to the computer unit a branch for the forwarding of the swivel value either to an automatic for consideration in the current or next metal strip and / or a display of a swivel recommendation for the helmsman.
  • the automatic and / or the display is connected to a swivel setpoint comparator and / or a swing-Istwertner and that both are connected to a position control of the hydraulic adjustment on the drive side or to a position control of the hydraulic adjustment on the operator side ,
  • a further embodiment is that the position controls, including a position control for the absolute position setpoint, are each connected to a cylinder force control for the drive side and the operator side.
  • Fig. 1A is a stable strip during rolling of a metal strip 1 is shown, wherein the rolled strip end 1a enters the respective last roll stand 2 a hot strip rolling mill 3.
  • the rolling forces are in each case symmetrical to the middle of the framework 2a (FIG. Fig. 2 ) acting effectively.
  • the adjustment of the rollers 10,11 is not parallel, but on the drive side 4 further open than on the operator side 5.
  • This setting leads by the clamping of the metal strip 1 in the adjacent stands F1 and F3 to an asymmetrical band voltage distribution over the bandwidth whereby the strip is stabilized and prevents the metal strip 1 from running laterally.
  • the tape take-in speeds for the stand F2 on the drive side 4 and the operator side 5 are the same.
  • Fig. 1B is shown an unstable tape during the unthreading of the rolled strip end 1 a, wherein after the threading out of the rolled strip end 1 a from the frame F1 of the stabilizing strip tension is missing and there is different tape feed speeds between the drive side 4 and the operator side 5 of the frame F2.
  • the metal strip 1 is drawn in this case at a higher speed on the drive side 4, so that the rolled strip end 1a rotates and extends to the drive side 4 out.
  • Such a process is dangerous and can lead to the described damage.
  • the generated rolling forces on the drive side 4 and on the operator side 5 are compared or separately measured for each rolling stand F1, F2, F3, Fn ... and then evaluated. The direction and the value of the differential rolling force are calculated from these measured values.
  • the results of the respective measuring step are automatically used within the ongoing rolling process from roll stand (F1) to rolling stand (F2..F3..Fn) or adaptively from metal strip 1 to a new metal strip 1.
  • a recovery application is designed such that the measurement result for the helmsman in the control center is displayed on a monitor and the helmsman makes the correction manually during the rolling process.
  • Another utilization possibility is that after the threading out of the rolled strip end 1a for a selected strip length, an average value of the differential rolling force between the drive sides 4 and the operator sides 5 is formed and utilized for the respectively following metal strip 1.
  • Fig. 2 is a roll stand 2 from the hot strip rolling mill 3 ( Fig. 1 ), the work rolls 10 and back-up rolls 11 each on the drive side 4, wherein the belt tension is set to stabilize the belt run and for a high rolling speed.
  • measuring devices for measuring the rolling force on the driving side 4 and the operator side 5 described below are provided.
  • a branch 19 for the forwarding of the swivel 16 either connected to an automatic 20 for consideration when running or next metal roller 1 and / or a display 21 a swivel recommendation for the helmsman.
  • the helmsman's automatic slew setpoint 23 is routed to a branch 24 in which the values are passed to a hydraulic control / drive side position control (rollers) 25 and to a hydraulic control position control 26 on the operator side 5.
  • the swing setpoints 22 and 23 are added to the absolute position setpoint 27 and subtracted.
  • the position controls 25, 26 of the hydraulic actuators on the drive side 4 and on the operator side 5 operate with these position setpoints and are connected to a cylinder force control 29 and 30 for the drive side 4 and the operator side 5, respectively.
  • Fig. 3 For example, evaluations of the differential force at the rolled strip end 1a are shown. After the threading 31 out of the frame F i-1 , a mean value 32 of the differential force is formed for a specific time or strip length. For the remaining time or length of tape until unthreading 33 from the stand Fi, a relative deviation 34 is then integrated with this mean value. The size of the value thus calculated determines the size of the pan value 16 and the sign the direction of "pan”.
