Definitions

  • the invention relates to a Steckel hot rolling mill with at least one reversing roll stand, and to this reel, which is arranged upstream and downstream, and has torque-controlled drives.
  • Such Steckel hot rolling mills have torque-controlled reels, the control of which at constant moments during operation, in particular when rolling hot strips, however, produces insufficient rolling results.
  • Such reels with their sometimes large, inert masses result in tension fluctuations in the strip, which cannot be corrected by the torque control, so that the known systems only work with limited acceleration or deceleration may be driven.
  • Such limited acceleration or deceleration results in longer reversing times, lower rolling speeds and thus colder strip starts or strip ends, which in turn require higher rolling forces. Strong changes in the process variables such as temperature, rolling force combined with loss of tension due to reel imbalance and changes in mass flow lead to loss of quality and stability, e.g. for the band to run sideways.
  • the invention is therefore based on the object of developing a generic Steckel hot rolling mill in such a way that tensile and / or mass flow changes caused by changes in the process variables are optimally counteracted and that in particular thin hot strip can be rolled with constant, high quality. - 2 -
  • a looper is provided between the reels and the reversing roll stand, which delivers actual values for tension control and mass flow control. This means that certain trains can be set using the two loopers on each side of the reversing roll stand. If there are mass flow changes on the strip inlet or strip exit side, which are essentially characterized by strip speed changes, the strip winding speed or speed of the reel is regulated in the course of a mass flow control in order to adjust the mass flow to a setpoint.
  • the loopers have a torque control that causes a constant strip tension, a correction variable is applied as a function of the looper angle, and that a mass flow computer determines speed correction values for a speed control of the reel as a function of the looper angle. Due to the mass flow control superimposed on the train control, high-frequency interference can be corrected.
  • the reel is equipped with a mass flow feedforward control and / or mass flow feedforward control, it is ensured that changes, e.g. the nominal thickness values or changes in the roll stand geometry can be corrected before the occurrence of tensile or mass flow changes which would be recognized by the looper.
  • the reel shafts are assigned angle encoders, by means of which deviations in the winding or unwinding speed can be determined, which are applied to the tension regulators of the strip as pilot control variables. It is thereby achieved that changes in train or mass flow caused by eccentricities of the reel can be taken into account in the course of a pre-control in the regulation of the looper, without the looper causing errors first having to be recognized by the looper and only then having these errors corrected . It is essential for the functioning of the Steckel hot rolling mills according to the invention that the following loopers are used with low inertia, mass-optimized and high-frequency changes. A special geometry and the use of components of the looper that are optimized in terms of their mass mean that these very rapid changes in the train or mass flow can follow, so that the errors measured in this way can be counteracted via the corresponding control loops.
  • the invention is explained in more detail with reference to a drawing.
  • the figure shows a reversing roll stand 1, which is arranged between two drivers 2, 3.
  • Roller tables 4, 5 are provided between the drivers 2, 3.
  • Reels 6, 7 are shown upstream or downstream of the drivers, looper 8, 9 being placed between reels 6, 7 and drivers 2, 3.
  • a tension controller 10, 11 is assigned to each looper 8, 9.
  • the train controllers 10, 11 are supplied with train reference values s revl> s rev2 .
  • tensile stresses corresponding to actual force values are tapped as actual tension values s lstl , s istz and angles which, after conversion in corresponding tension correction computers 12, 13, are applied to tension controllers 10, 11 as tension correction values.
  • the tension control loops 10, 11 give the result of the target / actual value comparison on z. B. not shown positioning cylinder of the looper 8, 9th
  • the signals corresponding to the angular positions tapped at the loops 8, 9 are fed to mass flow computers 14, 15 and converted therein into speed correction values, which in turn are applied to speed controllers 16, 17.
  • Setpoint values are predefined for the speed controllers 16, 17 for the reel 6, 7 via an input device.
  • Actual speed values n actl , n act2 are tapped from the reels 6, 7 and the speed controllers 16, 17 are applied.
  • the speeds for the reel 6, 7 are determined in the speed controllers 16, 17 from the target values, the actual values and the correction values.
  • a roller speed control device 21 is assigned to the reversing roll stand 1 and also receives its setpoints from the input device 18.
  • the input device 18 has a correction computer which e.g. entered nominal thickness values for the reversing roll stand 1 in the course of a pilot control for the reel 6, 7 are converted into corresponding pilot control speeds which can be applied to the speed controllers 16, 17.
  • Material flow and / or train changes resulting from changes in the position or change of the material can be fed to a correction computer 22 which applies train correction values and / or speed correction values to the train controllers 10, 11 and / or the speed controllers 16, 17.
  • This also enables mass flow pre-regulation of the Steckel hot rolling mill as a function of changing parameters of the reversing roll stand 1. - 5 -

Abstract

L'invention concerne un laminoir à chaud Steckel comportant au moins une cage réversible (1), ainsi que des bobineuses (6, 7) placées en amont et en aval de celle-ci et possédant des systèmes d'entraînement dont le couple de rotation est régulé. Un tel laminoir doit être perfectionné afin d'empêcher de manière optimale les variations de tension et/ou de flux massique provoquées par les variations des paramètres du processus et de permettre également le laminage, notamment d'un feuillard à chaud mince, avec une qualité élevée constante. A cet effet, entre les bobineuses (6, 7) et la cage réversible (1) est disposé respectivement un couloir à boucles (8, 9) qui fournit des valeurs réelles pour la régulation en tension ainsi que la régulation du flux massique.
