Definitions

  • the invention relates to a method for correcting rolled metal strips horizontally bent in the strip plane, especially of metal strips with a strip thickness from 0.5 mm to 2.0 mm, the band edges of which form Horizontal arches from the one running in the longitudinal direction of the strip edge Straight lines deviate, after which the metal strip in question by means of at least one in the horizontal plane and / or vertical plane swiveling stretch bending roll becomes.
  • Japanese publication 60-111 723 deals with this Straightening of continuous metal strip.
  • individual rollers are swiveled in the strip plane.
  • the bending deformation changes as it passes of the aforementioned rollers. This is said to be inconsistent partial expansion and curvature can be compensated can.
  • the invention has for its object such Procedure to specify after which there are horizontally curved metal strips continuously and flawlessly in the longitudinal direction of the strip get straightened.
  • suitable device created by this method become.
  • the invention solves this problem with a generic one Method in that the band edge course of the relevant Metal strip at a predetermined distance after the Stretch bending reports are continuously measured on both sides, and that when determining a horizontal deviation the correction of the bending roll in one by the respective deviation of the given dimension - preferably on the short hinge side - is pivoted so that in the course of the According to stretch bending, a corresponding elongation of the horizontal sheet-free Band edge and thus that from the horizontal sheet resulting elongation compensated and consequently a Correction of the curved band is achieved.
  • As part of the Invention means "rolled metal strips" both cold rolled as well as hot rolled metal strips.
  • the invention goes from the knowledge that metal strips in the course of the Stretch bending in a plastic or at least semi-elastic state and therefore easy one Elongation of the band edge free of horizontal bends can be achieved can if one or more stretch bending rollers accordingly be employed.
  • This band correction on one side or the other of the band can be brought about is not only in the way a horizontal pivoting of one or more Stretch bending rolls possible, rather the swiveling one Stretch bending roll or can use several swiveling stretch bending rolls also pivotally mounted in the vertical plane be and consequently on one side and on the other side of the tape be raised and lowered.
  • every intermediate position between pivoting in the horizontal plane and vertical plane conceivable.
  • the wrap angle changes with the side Swiveling more sensitively than with the vertical one-sided Raise the stretch bending rollers.
  • the stretch bending rolls can be achieved. You always become one Swivel the bending roll (s) so that a sufficient Elongation of the short hinge side is achieved.
  • the Band correction preferably immediately after unwinding of the metal strip in question or behind an intermediate one Skin pass mill made to be right from the start Disruptions and standstills resulting from horizontal arches to avoid.
  • the invention also relates to a device for Implementation of the claimed method, with at least a tape unwind station, one of the tape unwind station downstream stretch bending straightening system with several stretch bending rolls and with a tension drum pull drive for the Metal strips, with at least one of the stretch bending rollers their two reel ends optionally around a hinge point is pivotally mounted.
  • This device is characterized in that the stretch bending straightening system in predetermined distance a measuring device for determining horizontal deviations from the straight line on both sides of the each continuous metal strip in the direction of strip travel is subordinate, and that the pivotable stretch bending roller depending on the measured values determined on the one or the other side of the hinge is pivotable.
  • the measuring device is preferably about 5 m to 20 m distance behind the stretch bending straightener.
  • the pivotable stretch bending roller in the horizontal plane and / or vertical plane around one of the two pivot points pivotable.
  • the swiveling Stretch bending roll is preferably a lower roll, on which the continuous metal strip lies on.
  • the pivotable Stretch bending roll can also be designed as a top roll, which against the continuous metal strip to reach a predetermined immersion depth can be set.
  • the pivotable stretch bending rolls in the horizontal plane and / or vertical plane around end points of articulation are pivotally mounted.
  • the pivotable stretch bending rolls a roll diameter from 40 to 60 times the strip thickness, the roll diameter from the first stretch bending roll to the direction of the strip last stretch bending roll also up to a maximum of 200 mm can.
  • the invention provides that the pivotable Stretch bending roll by means of a regulated actuator is pivotable, the interposition of a Control loop and the computer processing the measured values the measuring device is connected. The same applies to the case that several pivotable stretch bending rollers are provided are.
  • This device has at least one Tape unwinding station 4, one of the tape unwinding station 4
  • At least one of the stretch bending rolls 6a is at each of its two roll ends a pivot point 8 optionally pivotally mounted.
  • the Stretch bending system 5 is a measuring device at a predetermined distance 9 for determining horizontal arches 3 on both sides of the metal strip 2 passing through in the strip running direction subordinate.
  • the pivotable stretch bending roller 6a is shown on the swung one or the other side of the hinge.
  • the swiveling one Stretch bending roller 6a is in the horizontal plane and / or vertical plane pivotable about one of the two hinge points 8 and executed as a sub-role.
  • the pivotable stretch bending roll 6a a roll diameter from 40 to 60 times the strip thickness.
  • the swiveling one Stretch bending roller 6a is by means of a regulated actuator 10 pivotable, the interposition of a Control circuit 11 for the correction specification and the measured values processing computer 12 connected to the measuring device 9.
  • the "long" Hinge side L is still plastically stretched at about 0.3 to 0.5%.
  • the material solidifies due to the plastic deformation stronger on the short hinge side K than on the long hinge side L.
  • the long and short side of the hinge can become more solid Steels such as B. for IF steels (INTERSTITIONALFREE) on the long hinge side L again a light one Form ripple. This complicates or prevents trimming both sides of the tape equally. That is why further proposed in the plastic elongation of the Band cross section under tension the short band side K accordingly to stretch more so that both sides of the band after relief are the same length.
  • the stretch bending straightening system 5 between two Skin pass stands 13, 14 may be arranged.
  • the second skin pass mill 14 covers the necessary moves behind the Stretch bending leveling system 5. Behind the second skin pass mill 14 is followed by scissors 15 and at a distance of about 5 m from the stretch bending straightening system 5 with the measuring device 9 the measurement evaluation and correction specification. It actually lies the arc radius between 1,500 m to 5,000 m.
  • For the rest is another welding station 16 for connecting them Tape ends provided that after their corrective treatment in the stretch-leveling system 5 are exactly straight and themselves therefore also perfectly with each other by laser welding let welded.
