Definitions

  • the invention relates to a working method for rolling round cross sections of predetermined precise finished dimensions in a roll stand group, which is arranged behind a wire rolling mill and consists of closely arranged, adjustable horizontal, vertical and horizontal duo-roll stands.
  • the invention has recognized that, in practice, good round cross-sections can also be rolled with comparable good accuracy of the finished dimensions, if the roll speed is measured within the first two roll stands with a significantly higher pass reduction, so that only a small train occurs and when setting a decrease of 1% to 5% in the last roll stand, the force of the drive of this roll stand is controlled so that the cross section of the rolling stock between this roll stand and the previous one is not reduced.
  • the roll stand group for carrying out this working method can have a motor which drives the first and the second roll stand together and a motor which drives the third roll stand, with an adjustable current limitation.
  • the value of the stand suspension of the roll stands of the roll group can, as the invention further provides, be limited to approximately 0.001 mm / kN, and the rolls, on the fly, with a distance between the roll stands of approximately 600 to 750 mm, as roll disks, have a disk diameter have from 130 to 300 mm.
  • Known loop formers can be arranged in front of and behind the roll stand group, which ensure a transition from the preceding and the subsequent units of the roll train which does not influence the dimensions of the rolling stock itself and the operation of the roll stand group.
  • the circumferential lines of the bottom regions of the caliber channels forming these roll calibers advantageously run approximately oval and then straight towards one another at an acute angle in the direction of the respective two peripheral edges of the caliber channel.
  • the rolling stands 1 and 3 are designed as horizontal stands with overhung rolling disks 4 and 5 and the rolling stand 2 arranged between them is designed as a vertical stand 2.
  • the rolling disks 6 of this horizontal stand 2 are also not overhung - not shown. All stands 1, 2 and 3 are clearly next to each other.
  • the stands 1 and 2 are driven together by a motor 8 via a gear 7 and the stand 3 separately from a motor 9.
  • the diagram according to FIG. 2 shows the course of the current limitation I M as a function of the rolling speed, which takes the rolling work WA and the mechanical friction MR into account.
  • the excess power required to operate the roll stand must always be smaller than the tensile strength of the rolling stock in order to avoid influencing the cross section.
  • FIG. 3 shows the course of the circumferential lines of the calibres of the stands 1 (FIG. 3), 2 (FIG. 4) and 3 (FIG. 5).
  • the circumferential lines run elliptically oval and then, in areas R in the direction of the respective two peripheral edges K of the calibres, at an acute angle to one another, the angles in the caliber of the stand 1 being 30 ° -60 ° , in the caliber of the scaffold 2 30 ° -60 °.
  • the finished caliber of the stand 3 is then a round caliber.
