Definitions

  • the invention relates to a roll stand for the stepped rolling of a metal strip, in particular of steel, aluminum, copper or a copper alloy.
  • the invention further relates to a rolling train with at least one such rolling stand and a corresponding method.
  • Roll stands and methods for producing step-shaped thickness profiles across the width of a strip-shaped metal strip are known in the art, e.g. from German patent application DE 198 31 882 A1 or German Patent DE 101 13 610 C2 basically known.
  • desired thickness profile e.g. Stair profiles recommend the two documents to longitudinally roll the metal strip, which originally typically has a rectangular cross-section, with a plurality of pressure rolls offset in the rolling direction.
  • the offset in the transport direction of the metal strip or juxtaposed pressing rollers each press into the supported by a support means metal strip and deform it in this way as desired in the width direction.
  • the pressure rollers proposed for use in said publications allow only a locally very limited processing of the metal strip in a narrow range in the width direction; It is therefore, as I said, a plurality of such pressure rollers in a staggered arrangement required lent to e.g. to roll wider steps into the metal band. Due to the large number of required pressure rollers and their staggered arrangement, the structure of such known rolling stands for realizing step profiles in metal bands is quite expensive.
  • This object is solved by the subject matter of patent claim 1.
  • the material rolled off from the height of the metal strip or the material flow resulting therefrom is evenly distributed in the longitudinal direction of the metal strip, advantageously without corrugation.
  • the inventively used for this mill stand is structurally simple and space-saving, because it has only transversely to the direction of the metal strip juxtaposed part rollers, but not a plurality of staggered in the direction of running part rollers.
  • sub-rollers are arranged "at the same height" next to each other, means that the side rollers arranged side by side on one side the metal strip are not offset in the transport direction of the metal strip to each other.
  • the invention relates only to the reduction in thickness of pre-profiled step profiles, wherein the advantageous effect that the resulting metal strip is wave-free, occurs only when the Dickenreduk- tions for the individual stages transversely to the transport direction of the metal strip under consideration of the claimed law individually calculated and performed become.

  • a setting device with knowledge of the step heights of the incoming step-shaped pre-profiled metal strip.
  • the rolling stand is designed for hot rolling or cold rolling of the metal strip.
  • the above object of the invention is further achieved by a rolling train, in particular a tandem system.
  • This rolling train then comprises a first roll stand with profile or caliber rolls for the step-shaped pre-profiling of the metal strip.
  • at least one second rolling stand is then connected downstream of the first rolling stand or roughing stand, this second rolling stand being designed according to the invention.
  • the at least one downstream roll stand then takes place a reduction in thickness of the stepped metal strip, wherein the heights of the individual adjacent stages are individually reduced according to the claimed law.
  • the second rolling mill can be followed by further rolling mills according to the invention.
  • the inventively designed upstream rolling mills then take over the necessary provision of a step-shaped pre-profiling of the metal strip for each downstream rolling stands according to the invention.
  • a plurality of roll stands according to the invention arranged one behind the other is required, in particular, if the thickness of the metal strip is to be greatly reduced.
  • a strong reduction in thickness can also be realized by a single reversing stand, which is designed according to the invention.

  • the two outer sub-rollers 110-1, 110-3 are mounted in FIG. 1 by way of example on a common axis A and, if appropriate, are therefore also respectively set in the same manner and to the same extent relative to the support device 120.

  • the method according to the invention can be used both during hot rolling and during cold rolling of metal strips.
