Definitions

  • WO 2011/073 016 A1 forms the basis for the preamble of claims 1 and 5.
  • the coiled collar Before pulling off the reel mandrel, the coiled collar is turned so that the end of the tape protrudes only slightly beyond the lowest point of the coil and thus the bundle is stabilized by its own weight.
  • reeling the metal strip to the coil usually occurs already a plastic deformation of the metal strip. Nevertheless, in some cases a spontaneous popping up or unrolling of an unsecured federal government may occur.
  • the cause of this are elastic residual stresses in the coils of the coiled federal.
  • the size of these residual stresses depends on several factors, for example the strip thickness and the yield stress at the coiler temperature. In particular, in high-strength grades with a yield stress of about 500 MPa (or more) and a thickness of about 12 mm (or more) such a spontaneous popping or rolling may occur.
  • a straightening unit can according to the WO 2008/000 348 A1 the combination a lower roller and an upper roller of the drive roller unit plus a drive roller unit upstream, engageable with the metal band hold-down roller can be used.
  • a straightening unit upstream or downstream of the driving roller unit can be used as a straightening unit.
  • the upstream or downstream straightening unit comprises in each case three straightening rollers which are sequentially successive and which are set alternately on one and the other side of the metal band, at least one of which is adjustable against the metal band.
  • EP 0 906 797 A1 From the EP 0 906 797 A1 It is known to arrange between the drive roller unit and the reel a drafting funnel with multiple work rolls, wherein the metal strip is deflected at each work roll. In addition, cooling of the metal strip can take place between the work rolls. By means of the arrangement of EP 0 906 797 A1 In particular, a stress distribution of the metal strip over the bandwidth can be influenced.
  • the object of the present invention is to provide means by which a plastic deformation of the end portion of the metal strip can be effected in a simple manner.
  • a method of the aforementioned type is configured in that the plastic deformation of the end portion is a length of the end portion greater than half of the outermost turn of the coil and smaller than the outermost turn of the coil and is supported by a rebaring unit upstream of the reel, wherein the straightening unit of a combination of a lower roller and an upper roller of the drive roller unit plus one of the drive roller unit upstream, engageable with the metal band hold-down roller consists.
  • the asymmetric loading of the sides of the end section with the cooling medium can be done as required before reeling the end section and / or reeling the end section and / or after reeling the end section. Furthermore, the asymmetrical loading of the sides of the end section with the cooling medium can be carried out as required with a constant coolant quantity, with varying coolant quantity or intermittently.
  • the extent of asymmetric loading is preferably chosen such that the radius of curvature is at most as large as half the coil diameter. This ensures that the end portion bears under pressure at the next inner turn of the coil. An automatic popping or unwinding of the coil is thereby reliably prevented.
  • a metal strip 1 is to be reeled by means of a reel device.
  • the metal strip 1 may consist of steel.
  • the metal strip 1 may be made of a different metal, such as aluminum or copper.
  • the metal strip 1 has been previously rolled in a rolling mill, not shown, and then cooled in a cooling section, also not shown.
  • the reel device initially has a drive roller unit 2.
  • the driving roller unit 2 has a lower roller 3 and an upper roller 4.
  • the lower roll 3 is often rigidly arranged.
  • the upper roller 4 is often adjustable to the lower roller 3. This is in FIG. 1 indicated by a double arrow within the upper roller 4.
  • the upper roller 4 can be displaced horizontally.
  • the drive roller unit 2 the metal strip 1 is deflected from a first transport direction x in a second transport direction y and then fed in the second transport direction y a reel 5 of the coiler.
  • the first transport direction x is usually horizontal.
  • the second transport direction y is directed obliquely downwards in the rule.
  • the metal strip 1 is coiled to a coil 6.
  • the reel 5 has a coiler mandrel 7.
  • the coil 6 has an initial diameter d.
  • the initial diameter d corresponds to the diameter of the coiler mandrel 7.
  • the diameter of the coil 6 increases until it reaches a final diameter D.
  • the final diameter D corresponds to the coil diameter of the finished coiled coil 6.
  • an end portion 8 of the metal strip 1 after reeling such plastically deformed is that he - see FIGS. 2 and 3 - Is curved in the action-free state with a sufficiently small radius of curvature R.
  • the radius of curvature R is preferably at most as large as half the coil diameter D.
  • the end portion 8 can be separated from the rest of the coil 6 and then placed on the side edge, so that the end portion 8 can roll freely. In this state, the end portion 8 assumes the radius of curvature R. This - usually fictional - state is in FIG. 3 shown. In practice, the end portion 8 remains part of the coil 6. The end portion 8 must therefore necessarily assume a radius of curvature which is equal to half the coil diameter D. However, the end portion 8 is bent, starting from the non-impact state, elastically outward. It is therefore due to its elastic Aufbiegung under pressure at the next inner turn 9 of the coil 6 at.
  • the length of the end portion 8 may be determined as needed.
  • the length of the end portion 8 is as shown in FIG. 2
  • the length of the end portion 8 may correspond to a circumferential angle ⁇ of 190 °, 200 °, 210 °, ..., 340 °, 350 ° or less than 360 °.
  • intermediate values can be realized, for example 217 ° or 312 °.
  • the reeling device has a deformation device.

  • the deformation device may comprise a straightening unit, which is arranged upstream of the reel 5.

  • the plastic deformation takes place before the end section 8 is reeled by means of the straightening unit.
  • the straightening unit 10 is referred to below as the upstream straightening unit.
  • the upstream directing unit 10 comprises as shown in FIG FIG. 1 at least three straightening rollers 11 to 13.
  • the straightening rollers 11 to 13 follow one another sequentially in the first transport direction x. They are employed alternately on one and the other side of the metal strip 1.
  • the straightening rollers 11 to 13 may be driven individually or in groups. Alternatively, they may be designed without drive. At least one of the straightening rollers 11 to 13 can be adjusted to the metal band 1.
  • the middle straightening roller 12 of the upstream straightening unit 10 can be attached to the metal band 1. This is in FIG. 1 indicated by a double arrow in the middle straightening roller 12 of the upstream straightening unit 10.
  • the two outer straightening rollers 11, 13 of the upstream straightening unit 10 can be adjusted to the metal band 1. This is in FIG. 1 indicated by a double arrow between the two outer straightening rollers 11, 13 of the upstream straightening unit 10.
  • the drive roller unit 2 is followed by a straightening unit 14.
  • This straightening unit 14 is referred to below as a downstream straightening unit.
  • the downstream alignment unit 14 thus comprises, as shown in FIG. 1 at least three straightening rollers 15 to 17.

  • the straightening unit has a hold-down roller 18 in addition to the lower roller 3 and the upper roller 4 of the driving roller unit 2.
  • the hold-down roller 18 is arranged upstream of the drive roller unit 2. It is adjustable to the metal band 1. This is in FIG. 1 indicated by a double arrow orthogonal to the first transport direction x at the hold-down roller 18.
