Definitions

  • Hot strip reels are arranged at the end of hot strip mills and have the function to wind hot strip after rolling into coils.
  • the tape is wound while under tension to produce a sufficiently tightly wound waistband and to avoid cracking of the waistband after the finished winding.
  • the tension is also necessary to bend the band around the coiler mandrel and thus plastically deform. Especially with thick bands, large tensile forces are necessary to overcome the plastic bending moment.
  • the tape is guided by a driver consisting of an upper drive roller and a lower drive roller and transported to a coiler mandrel.
  • the band is wound around the mandrel with the assistance of pressure rollers and a collar is formed, which is drawn from the coiler mandrel after the band has been completely wound up.
  • a predetermined tension in the belt is set between the driver and the reel dome.
  • the EP 0 469 483 discloses hot strip reels in which the strip is pressed against a mandrel by four pressure rollers.
  • the JP 58 058 931 A discloses a reel in which the tape to be wound is pressed by three engagable pressure rollers on a mandrel. Each pressure roller is pivoted about its own pivot point by means of its own hydraulic cylinder.
  • the invention is therefore based on the object to provide a method by which a rolled strip with strip thicknesses of 7 mm and more, low coiling temperatures and higher-strength grades such as tube material when winding to a covenant from the beginning completely on the reel dome and subsequently completely wound on the already Coils of the federal government is applied. Furthermore, a device for winding hot strip to be specified.
  • the pre-bending of the hot strip firstly ensures that the hot strip rests completely on the reel mandrel or on the subsequent turns from the beginning of the reeling, and secondly it makes it possible to wind it with a lower strip tension, since the hot strip is not only deformed by the pressing devices, but also additionally by the Vorbiegevorraum.
  • the invention also relates to a device for winding hot strip, with the features of claim 5.
  • the deformation takes place such that the hot strip receives a radius which corresponds to the radius of the coiler mandrel or is slightly smaller.
  • the hot strip is from the beginning of winding on the coiler mandrel or is pressed due to the bias by the slightly smaller radius completely by the pressing devices to the coiler mandrel.
  • a controller / controller for winding hot strip is designed so that a Vorbiegevortechnisch arranged between the first and the second pressing device is moved away from the coiler mandrel or to the coiler mandrel that, depending on the collar diameter, the thickness of the hot strip, the Quality of the hot strip and / or the temperature of the hot strip a concern of the hot strip at the beginning of winding on the coiler mandrel is always given.
  • the Vorbiegevortechnisch is moved away both from the coiler mandrel and to the coiler mandrel.
  • the distance of the Vorbiegevoroplasty to the first pressing device and the second pressing device can be changed.
  • the Vorbiegevoroplasty is equipped with a first pulling or pushing device that moves the Vorbiegevortechnische to the coiler toward or away from her.
  • At least one second pulling or pushing device is arranged so that the pre-bending device is moved towards or away from the first pressing device or the second pressing device.
  • the respective position of the pre-bending device to the reel mandrel, the first pressing device and the second pressing device is respectively dependent on the thickness of the hot strip, the quality of the hot strip and the temperature of the hot strip.
  • control / regulation provides that instead of the position of the Vorbiegevorplatz the tensile force during winding of the hot strip is taken into account.
  • known devices are used to determine the strip tension and, depending on the determined values, the Vorbiegevortechnisch is controlled / regulated.
  • FIG. 1 is a side view of a known device for winding hot strip 1 is shown. That from a roll stand, not shown, hot strip 1 is performed between an upper drive roller 2 and a lower drive roller 3 and transported from there to a reel mandrel 4. For pressing the hot strip 1 to the coiler mandrel 4 a plurality of pressing devices 7, 8, 9 are arranged around this. When winding a hot strip 1 of higher-strength steel grades and / or strip thickness of 7mm or more, the hot strip 1 does not apply directly to the reel mandrel 4. A frictional engagement between reel mandrel 4 and hot strip 1 takes place only when the hot strip 1 has reached a wrap angle of 180 ° or more.
  • the hot strip 1 is spaced at the beginning of the winding process of the reel mandrel 4 and a tensile stress in the hot strip 1 between the driver rollers 2, 3 and the coiler mandrel 4 is not established. Furthermore, the diameter of the coil eye, ie the inner diameter of the wound hot strip 1, deviates from the diameter predetermined by the coiler mandrel 4.
  • FIG. 2 shows an inventive device for winding hot strip 1.
  • the known from the prior art device parts are used under the same reference number.
  • the hot strip 1 transported from the upper drive roller 2 and the lower drive roller 3 to the reel mandrel 4 is pressed by the first pressing device 7 in the direction of the reel mandrel 4 in the direction radially.
  • the hot strip 1 is pressed radially outward by a pre-bending device 6 from the coiler mandrel 4.
  • the pre-bending device 6 is arranged on the inner side of the winding 10, between the coiler mandrel 4 and hot-rolled strip 1, while the pressing devices 7, 8 and 9 come into contact with the hot-rolled strip 1 on the outer side of the winding.
  • the Vorbiegevorides 6 bends the hot strip 1 to an equal or higher curvature than the hot strip 1 would normally require to abut the coiler mandrel 4.
  • FIG. 3 the control scheme is shown.
  • a measuring device determines the band diameter, the strip thickness, the temperature of the hot strip and / or the quality of the material used. With these parameters, the desired position or the desired force of a Vorbiegevoroplasty (6) is determined in a computing device and adjusted by means of an actuator. By means of a further measuring device, the actual position or the actual force is determined and compared with the desired position or the desired force and, if necessary, changed or adjusted by the control device.
