Definitions

  • Such an adjustment method and the roller table corresponding thereto are For example, from DE 32 30 866 C2.
  • JP-A-61 238 414 describes such a cooling device.
  • a temperature comparison dictates how far a right and a left left drain box are moved under a nozzle bar back and forth.
  • curvature of the metal strip by a measuring device determined and taken into account in the separate method of the discharge boxes.
  • a device in which a hot Steel plate is passed from a rolling stand in a cooling device. It will the hot steel plate is detected by measuring devices in their width. The determined Width is used to arrange vertically aligned edging sheets that the hot steel plate is shielded by a right and a left edging plate becomes. The edging plates are positioned laterally of the steel plate.
  • JP-A-59 232 235 shows a device, in the shielding a cooling medium from the surface of a hot steel plate. To set the Shielding the position of the hot steel plate is determined by sensors.
  • JP-A-01 062 208 in a cooling device, the center of a strip determined by the edges of the strip detected by a thermometer become.
  • a control device a device is addressed, which the baffles laterally adjusted. By such a measurement will also noted a curvature of the strip.
  • Metal strips are cooled in the prior art to produce desired metallurgical To achieve properties. Since the edge areas of the metal strip in the Usually colder than the central region, it is a cooling medium in the prior art shielded from the edge regions of the metal strip. This should be a uniform temperature distribution can be achieved behind the cooling section.
  • the object of the present invention is an adjustment method for two shielding and a corresponding roller table available to provide, by means of which an even more uniform temperature profile in the Metal strip is achievable.
  • the problem is solved for the adjustment process in that a distance of the Bandmitte is detected by the roller conveyor center, the shielding with respect to the Roller table center be adjusted asymmetrically and the distance through the asymmetrical Adjustment of the shielding is compensated.
  • the task for the roller table is achieved in that the shielding elements of adjusting drives with respect to the roller table center asymmetric are adjustable, that it has a sensor device by means of which a distance of the band center from the roller table center is detectable, and that the sensor device is coupled control technology with the adjusting drives.
  • Roller table can in the presence of appropriate sensor devices and hereby corresponding detection of the corresponding deviations, in particular a distance of the center of the middle of the roller table, an asymmetry of the Temperature variation over the bandwidth in front of the shielding and an asymmetry the temperature profile across the bandwidth behind the shielding recorded and compensated.
  • the roller table is structurally particularly simple, if the shielding are arranged above the roller table, the shielding as in the transport direction extending longitudinal grooves are formed and the cooling medium of fed to the longitudinal grooves transversely to the transport direction extending transverse grooves becomes.
  • a roller table has a plurality of transport rollers 1, on which a metal strip 2 is transported in a transport direction x.
  • the roller table has a roller table center 3.
  • the metal band has a band beginning 4, a band center 5 and a metal band width b.
  • the metal band 2 extends over the metal strip width b from an edge region 6 to a further edge region 6.
  • the metal strip has in front of a generally designated 7 cooling section on the Metal bandwidth b a temperature profile. Also behind the cooling section 7 the metal strip 2 has a temperature profile over the metal strip width b.
  • the metal strip 2 In the region of the cooling section 7, the metal strip 2 with a cooling medium 8, z. As water 8, applied so that it is cooled.
  • shielding elements 9 are arranged, by means of which the cooling medium 8 of the Edge regions 6 of the metal strip 2 can be shielded.
  • the shielding 9 be adjusted by adjusting 10 so that the temperature over the metal strip width b seen in the transport direction x behind the shielding 9 is approached a desired temperature profile.
  • the setpoint temperature profile is a uniform temperature distribution over the bandwidth b.
  • each shielding element 9 its own adjusting drive 10 assigned, by means of which he mechanically independent of the other Shielding element 9 is adjustable.
  • the shielding elements 9 via a differential gear 12, z. B. a planetary gear 12, coupled together.
  • the shielding elements 9 of the one adjustment symmetrical to each other and from the other adjustment mechanically antisymmetric adjusted to each other.
  • the temperature profiles is in front of and behind the shielding elements 9 each have a sensor device 13, 14 are arranged. Due to the recorded temperature profiles is an asymmetry of the temperature curves over the bandwidth b in Transport direction x seen before and behind the shielding 9 detected.
  • the corresponding asymmetries are input to a controller 15, which is associated with the adjusting drives 10.
  • the control device 15 determined then corresponding adjustments for the shielding 9, so that the Asymmetries of the temperature profiles in front of and behind the shielding elements 9 be compensated.
  • the metal strip 2 has a strip beginning 4.
  • the adjustment drives 10 of a control unit 16 presets predetermined, to which the shielding elements 9 are set in advance.
  • the shielding 9 then from the adjustment drives 10 according to the detected asymmetries the temperature gradients and corresponding to the detected distance d Adjusted settings.
  • the adjustments are made by the control device 15 of the control unit 16 transmitted.
  • the control unit 16 modifies based on the Nachein sueden the default settings.
  • the shielding 9 then in advance on the modified Presets set. This results in a self-learning behavior of the adjustment process.
  • FIG. 3 shows schematically the determination of the settings for the shielding elements 9.
  • the sensor devices 13, 14 are provided with correction value detectors 17, 18 connected.
  • the correction value determiners 17, 18 determine from the detected temperature distribution in front of or behind the shielding 9 a Asymmetry value for the edge regions 6 and from this a Verstellasymmetrie for the shielding 9th
  • the sensor device 13 is further connected to a tape position determiner 19. This determined from the detected temperature profile, the distance d of the band center 5 from the roller table center 3.
  • the determined correction values and the determined distance are the control device 15 predetermined.
  • the controller 15 are further from the control unit Preset 16 default settings.
  • the control device 15 determines corresponding adjustments for the shield 9.
  • These newly determined Settings are sent to the Control unit 16 is returned, so that they correspond to the default settings can modify.
  • the shielding elements 9 as a simple baffles 9 formed, which are adjusted by means of the threaded spindles 11.
  • the shielding elements 9 are formed as longitudinal grooves 9, in the transport direction x run.
  • the cooling medium 8 collected by them is fed to transverse channels 20, which run transversely to the transport direction x. Of these, the cooling medium 8 then discharged to the outside.
  • FIGS Querrinnen 20 between the adjusting 10 and the roller table arranged.
  • the shielding 9 instead of threaded spindles 11 adjusted by roller chain drives 21.
  • the transverse channels 20 protect the adjustment drives 10 and / or the adjusting elements 11 and 21 against overheating and before possible uproar of the beginning of the strip 4.
  • An attachment as well as the adjustment the shielding elements 9 can be seen in the transport direction x according to FIG take place in two positions.
  • the shielding elements 9 are arranged over the roller table. In principle, it would also be possible to have such a shielding arrangement to arrange below the roller table.
