Definitions

  • the invention relates to a roll stand for sheet-like rolling stock, in particular for reversing rolling, with two work rolls, between which the Rolled material is guided and assigned to each of these work rolls Back-up rolls, both the back-up rolls and the work rolls each in Chocks are stored and the support rollers are assigned bending blocks.
  • the work rolls for supporting against the direction of displacement are assigned support devices with hydrostatic support elements, which are provided with hydrostatic pressure pockets facing the surfaces to be supported and are arranged and designed to be controllable parallel to the longitudinal axis of the work roll to be supported.
  • the support rollers are in this case designed as a deflection adjustment roller with a roller jacket supported around a carrier by means of support elements. The work rolls can be moved horizontally with the support devices assigned to them in the roll stand parallel to the rolled material web.
  • chocks can also be moved horizontally Work rolls according to EP 0 233 597 B1, the displacement in this Case is carried out by handlebar arrangements by trained as an eccentric Swivel pins are guided and their movement is adjustable.
  • EP 0159 796 A1 to influence the Deflection of the work rolls in the direction or against the direction of the To take movement of the rolling stock.
  • the object of the invention is to offset the offset by simple means Work roll axes from the level of the backup roll axes in a relative large area to allow for the most varied. To be able to face deflections.
  • the support rollers 1 are mounted in chocks 2 and can be pivoted about their axes by hydraulic cylinders 6.
  • the upper and lower back-up rolls are adjusted in a known manner by cylinders 14 and 15, respectively.
  • the upper back-up roll is balanced with the cylinder 9.
  • the hydraulic cylinders 6 and the cylinders 9 for balancing the upper support roller are fastened in cylinder blocks 7.
  • the backup roll chocks 2 are held in the sliding blocks 10 and wear plates 11.
  • the sliding blocks are guided vertically in the wear plates 12 and 13.
  • the work rolls 3 are in turn stored in chocks 4, these with Bending blocks 5 are connected, which in turn in the support roller chocks 2 are fixed.
  • Adjustment means 8 are articulated on the support roller chocks 2, this in this embodiment with the hydraulic cylinders 6 be operated.
  • the bending blocks 5 can be a substantially horizontal force is applied, leading to a Swiveling the bending blocks and thus those connected to them Chocks 4 of the work rolls 3 leads.
  • these work Adjustment means from both sides onto the bending blocks so that a Swivel this in both directions axially parallel to the Back-up roller axes is possible. In this way, the different Deflection of the work rolls can be counteracted when reversing.
