Definitions

  • the invention relates to a method and a system for Forming of metal strip in a hot strip mill from a finishing train, a cooling section, a driver and a reel system, according to the preamble of claims 1, 2 and 13 (see e.g. U.S.-A-4,316,376). It is known to metal after the casting process in a hot strip mill to certain thicknesses, then to roll them after a coiling process of a cold strip rolling mill for rolling to the final dimension. Here are the cold strip mill fed metal strip ever higher requirements in terms of its mechanical and geometric properties, especially its flatness.
  • a well-known means of producing flat hot strip is that Use of actuators. Stand with extremely thin tapes but currently hardly or no reliable hot strip flatness measurements to disposal.
  • the belt leaves the finishing train with an uneven part Flatness or stress distribution over the Bandwidth. This can lead to the fact that despite the same boundary conditions (such as geometric dimensions, trains, Temperatures, material, etc.) for tapes in quick succession rolled, different flatnesses arise in the cold strip.
  • the uneven flatness distribution of the hot strip then leads directly or indirectly through changed winding conditions on the reel (for example higher coilcrown) to different Flatness of the cold strip.
  • the deflection of the belt on the driver changes in the direction of the desired reel system due to the different Tension distribution across the width of the strip flatness.
  • the main influencing factors are the ground ones Driver shape, the wear of the driver rollers, the contact pressure as well as the thermal crown of the driver rollers. Indeed can optimize the driver grinding as well as a Change of driver role material or driver role changing practice improve the boundary conditions.
  • the main influencing factors are here the emerging coilcrown.
  • the shape of the coil depends of the strip contour, the strip flatness during reeling, the material strength (temperature, material quality) and the Reel train from.
  • the object of this invention is a method and a system for setting the desired flatness and Tension conditions in hot strip to provide in To get cold state flat belt.
  • the core of the invention is the provision of a method and a system, wherein the strip material after exiting the cooling zone alternately above and below at least two successive stretching judge work rolls under Formation of a stretch judge zone is performed, the Stretching judge work rolls are arranged offset to each other are that the metal strip on each stretcher judge work roll is redirected. Alternatively, the function of two Stretching judge work roles by the two alone Driver roles are taken over. The stretching judge zone will then by turning the top or bottom drive roller in the area before or after the original driving roller position created.
  • the stretching judge zone at the end of the hot rolling process will by additional straightening rollers according to the Traction rollers or trained by means of the traction rollers themselves.
  • the aforementioned German patent discloses a stretch bending straightener with a downstream Rolling stand.
  • the stretching judge zone can be in the metal strip before it Reeling to the coil the desired flatness or tension properties can be set. With that it gets through the use of a higher quality, already planned hot strip possible, negative influences from the upstream processes largely eliminate and the quality of the tape in to improve cold condition.
  • two stretcher judge work rolls are sufficient to form a stretch judge zone, wherein the metal strip is not rolled between the rollers, but bent and stretched between the successively arranged rolls becomes.
  • the stretching rollers according to the invention can already A sufficient degree of flatness has been set for hot strip be, so under certain circumstances entirely on the cold strip process can be dispensed with.

Through a special one Training the crown of this role of the second type can then existing flatness of the metal strip is compensated become. This can be uneven across the bandwidth Train distribution will be generated with the aim of To stretch the tape locally so that it is as cold as possible is plan.
  • this second stretcher judge work roll of the second type For optimal setting of the position or contact pressure of this second stretcher judge work roll of the second type the measured values for strip contour, strip temperature distribution, the strip thickness and the tension level as well as the information the legalities derived from the offline cold flatness evaluation etc. can be used. It can be different Straightener work roll settings over the length of the tape.
  • the lower drive roller can also advantageously perform the task the first stretch leveler work roll of the first type take.
  • the stretching judge zone can alternatively also by the upper and lower drive roller are formed. This will be achieves that when the reel has caught the tape head, the upper driver roller is swiveled sideways downwards and thus the belt is deflected on the drive rollers.
