Definitions

  • the invention relates to a bending device for four or multi-roll stands Work rolls, backup rolls and if necessary between work rolls and Back-up rollers arranged intermediate rollers, in which on both sides of each Bearing chock of the bending blocks attacking in the windows of the Roll stand are guided vertically, the vertically opposite each other Bending blocks of a pair of rollers towards each other via piston-cylinder units are movable away from each other.
  • a generic bending device is from the European patent application 0 768 125 A1 known. There the bending forces are transferred into the Bearing chocks of the rollers initiated, which in the windows of the mill stand Arranged pairs of cylinder rods are guided, the ends of which are indirect with the Roll stand are connected.
  • the known design of the bending device has however, the disadvantage that only either positive or negative bending forces in the Work rolls can be initiated, which is disadvantageous for the rolling process showed. Especially when changing from positive to negative bend Situations arise in which the work rolls lift off the backup rolls can, which leads to loss of quality in the rolling stock.
  • the object of the present invention is one known from EP 0 768 125 A1
  • EP 0 768 125 A1 To improve the bending device so that at the same time during the rolling process positive and negative work roll bending can occur and thus both a large possibility of variation in the adjustment of the band profile is possible, such as a process-precise adjustment of the roll bending can also take place.
  • the invention proposes that at each Bearing chock, a second vertically displaceable bending block on both sides who attacks independently of the first bending block via a Roller stand supporting piston-cylinder unit is movable.
  • the second bending block on first bending block is guided. This solution is ideal for reasons of space; because in The installation space is extremely limited in the windows of the roll stand.
  • a particularly favorable solution provides that the one in one with the rolling mill connected guide piece sliding first bending block with flat guides is provided, in which the second bending block is displaceable, and that the piston-cylinder unit to move the second bending block on a console is supported, which is arranged on the roll stand, projecting into the stator window.
  • the present invention thus sees two independently displaceable Bending blocks on the bearing chocks of the work rolls before, the first Bending block pair from the guide piece firmly connected to the roll stand is performed and the displacement of these bending blocks each in one Bending block arranged cylinders takes place with the other bending block are connected.
  • the second pair of bending blocks is in the first pair of bending blocks guided and axially shifted separately with cylinders firmly supported on the roll stand.
  • FIG 1 the bending device according to the invention for a four-high rolling mill with Work rolls 1, 2 and backup rolls 3, 4 are shown.
  • the bearing chocks 5, 6 of the Work rolls 1, 2 are each connected to bending blocks 8, 9, which by Stand window 12 arranged guide pieces 13 are guided.
  • the Guide pieces 13 are firmly connected to the spars of the roll stand 7.
  • the Bending blocks 8, 9 lying one above the other are made by means of two cylinders 15 spread apart or pulled against each other and thereby axially to the Guide blocks moved up and down, resulting in the positive or negative Work roll bending results.
  • the bending blocks 16, 17 are separately vertically displaceable in Flat guides performed, which are provided in the bending blocks 8, 9.
  • everyone Bending block 16, 17 is opened and closed individually by means of cylinders 18 axially in the bending blocks 8, 9 moves, each cylinder 18 firmly with the spars of the roll stand 7th connected is.
  • This also results in a positive or negative Work roll bending combined with the roll bending of the first bending blocks 8, 9 used, a simultaneous positive and negative bend on one or allows different rollers.
  • This allows, for example, the two Work rollers set different curvature curves through which the Belt cross-section profile can be varied from convex to flat to concave.
