Definitions

  • the invention relates to a rolling mill for rolling metallic strip, in particular steel strip, which has at least one rolling mill, an upstream reeling device and a downstream reeling device, wherein an S-reel unit is arranged between upstream reeling device and rolling stand and / or between rolling stand and subordinate reeling device.
  • the two having the band S-shaped leading rollers, wherein a first roller of the S-roller unit is arranged stationary and a second roller of the S-roller unit is arranged to be movable relative to the first roller and wherein the second roller arranged movably relative to the first roller on a Swivel arm is rotatably mounted, which is mounted on one side in a fixed space axis.
  • tailored blanks The essential feature of these components, which is of particular interest in this context, is that they have a variable thickness.
  • tailored blanks were mainly made by welding. However, for the production of flexible cold rolling has proven to be particularly advantageous, can be produced with the tailored blanks.
  • the thickness of the rolled stock is changed during rolling.
  • the change of the roll gap can be done periodically.
  • the change in thickness leads to mass flow disturbances and to tensile fluctuations, in particular on the inlet side, but also on the outlet side of the roll stand.
  • the dynamics of the reel motors are no longer sufficient for their compensation, so that in such systems so-called dancer rollers are used between the rolling stand and the reels.
  • a cold rolling mill for cold rolling of metallic strip and has a single stand with means for adjusting the roll gap and a reeling the upstream of the cold roll stand reeling device for unwinding the tape and a reel downstream reel means for reeling the tape.
  • a strip store for mass flow regulation or strip tension control of the rolling process is provided between the upstream reeling device and the rolling stand.
  • This tape storage consists of at least three rollers, wherein the middle roller is designed as a dancer roll and can be moved perpendicular to the conveying direction of the tape.
  • the dancer rollers described in said documents are connected to a linear actuator, with which they can be controlled or moved in a direction perpendicular to the conveying direction of the tape direction. This can fulfill the tape storage function which is indispensable for flexible cold rolling.
  • Looper ie rollers that are applied to the run or guided to the rolling mill band, for example, to make a tensile force determination in the band can.
  • S-roll units S-rolls
  • the invention is therefore based on the object, a rolling mill for rolling metallic strip of the type mentioned in such a way that can be achieved with simple means and thus in an economical manner that both a band storage function, especially in flexible rolling, is given as well as a Defined controllable Werner-Fielding-Fielding-Fielding-Fielding-Fielding-Fielding-Fielding-Fielding-Fielding-Fielding-Fielding of a rolling mill for rolling metallic strip of the type mentioned in such a way that can be achieved with simple means and thus in an economical manner that both a band storage function, especially in flexible rolling, is given as well as a Defined controllable Werner between roll stand and reels can be kept defined.
  • This object is achieved in that the spatially fixed axis of the axis of rotation of the first roller corresponds, wherein the pivot arm in a remote from the fixed axis fulcrum a linear actuator is articulated and wherein the fulcrum is located on a connecting line between the axes of rotation of the two rollers.
  • Both axes of the rollers of the S-roller unit are arranged parallel to each other.
  • means for driving at least one of the rollers of the S-roller unit can be provided.
  • the invention proposal is advantageously used in a cold rolling mill.
  • the rolling stand is preferably provided as a single frame.
  • the proposed system is particularly suitable for flexible rolling, which is why the rolling stand can have means for flexibly adjusting the roll gap.
  • the belt transport or its handling is finally improved by the fact that at least one of the reel devices is equipped with means for speed control.
  • Fig. 1 schematically shows a rolling mill, in which a coiled steel strip 1 is unwound from an upstream coiler 3 and a single cold rolling mill 2 is supplied.
  • a downstream reeling device 4 is provided, which rewinds the rolled metal strip 1.
  • the reels 3, 4 are provided with drives, not shown, so that the tape 1 in a controlled or regulated manner and can be wound up.
  • the tape 1 has - viewed in its longitudinal direction - a non-constant thickness. That is, during the rolling process, the roll gap is changed according to a predetermined profile to produce a strip whose thickness changes periodically.
  • an S-roll unit 5 or 6 is arranged both between the upstream reeling device 3 and the rolling stand 2 and between the rolling stand 2 and the downstream reeling device 4.
  • Each S-roller unit 5, 6 has two rollers 7 and 8 or 9 and 10, which are arranged in a conventional manner to each other so that the band 1 is guided S-shaped. Due to the consequent wrapping of the rollers 7, 8, 9, 10, it is possible, with appropriate drive of the rollers to transmit a force to the belt 1 and so the desired tensile force in the belt 1 between the S-roller unit 5, 6 and the rolling stand 2 to hold.
  • the S-roll units 5 and 6 are as in Fig. 2 clearly structured.
  • One roller 9 (or 7) which feeds the belt 1 to the rolling stand 2 or removes it from it, is mounted in a stationary manner.
  • the other end of the pivot arm 11 is mounted on a fixed axis 12, which corresponds to the axis of rotation of the first roller 9, 7.
  • a linear actuator 14 is articulated, this being designed as a hydraulic piston-cylinder system.
  • the supply of the actuator 14 with hydraulic oil is in Fig. 2 indicated.
  • the pivot point 13 can be raised or lowered, so that the second roller 8, 10 can be pivoted about its pivot axis 12. This results in a longer or shorter distance for the strip 1 between roll stand 2 and reel devices 3 and 4, whereby it is the S-roll units 5, 6 possible to exercise a tape storage function.
  • the described construction of the rolling plant and in particular of the two S-roll units 5, 6 makes it possible to compensate for the mass flow change occurring during flexible cold rolling and at the same time to build up that draw difference between rolling stand 2 and reel devices 3, 4 with a very simple rolling process is possible. With a correspondingly fast control of the linear actuator 14, it is possible to compensate for the mass flow disturbances without significant pull fluctuations.
  • the strip thickness control can be improved. It becomes possible to make the settings of the tensile stresses favorable for the rolling process without regard to the tensile stresses present at the reeling devices.
