Definitions

  • the invention relates to a rolling device, in particular a push roll stand for use in flat rolling, according to the preamble of claim 1, see for example DE - 124 85 99 B ,
  • Roll stands are well known in the art.
  • a flat rolling mill is usually designed so that there is a symmetrical deformation of the rolling stock between the work rolls.
  • the roll diameter, the peripheral speed and the friction conditions of the two work rolls are chosen as equal as possible, so that there are only the slightest variations.
  • Such rolling stands are for example by the DE 33 23 641 A1 known.
  • a rolling device with a stator and two sets of rollers with at least two rollers which are arranged in a stator of the rolling device, wherein between two rolls of the two sets of rolls a rolling stock for rolling is feasible, wherein at least the rolls of a set of rolls in the rolling direction viewed relative to the stator are displaceable, wherein between a roller bearing for receiving the rollers and the stator respectively on both sides of the roller bearing adjustment means are provided.
  • the displaceable set of rolls prefferably comprise at least two rolls, with adjusting means being arranged on both sides of the at least two rolls.
  • the adjusting means are arranged substantially at the level of the respective roller and / or the respective roller axis, viewed in the direction perpendicular to the rolling direction.
  • the displaceable roller set has a common roller bearing for at least two of its rollers, wherein the Adjusting means attack substantially at the height of the respective roller on the roller bearing, viewed in the direction perpendicular to the rolling direction.
  • the upper roller set and / or the lower roller set is displaceable.
  • At least one roller such as, for example, the work rolls, of the upper and lower roller sets have a different diameter.
  • the adjustment means have hydraulic and / or mechanical adjustment mechanisms.
  • rollers in particular the work rolls, the two sets of rolls are operable at different speeds or peripheral roll speeds.
  • FIG. 1 schematically shows a representation 1 of two work rolls 2,3, which roll a rolling stock 4 with symmetrical arrangement of the rollers 2,3.
  • the forming zone 5 of the rolling stock 4 is formed symmetrically.
  • FIG. 2 schematically shows a representation 10 of two work rolls 11,12, which roll a rolling stock 13 with asymmetric rolling condition with symmetrical arrangement of the rollers 11,12.
  • the forming zone 14 of the rolling stock 13 is formed asymmetrically.
  • the rollers 11 and 12 are formed differently large.
  • the roller 11 has a smaller diameter than the roller 12.
  • FIG. 3 schematically shows a representation 20 of two work rolls 21,22, which roll a rolling stock 23 with asymmetric rolling condition with symmetrical arrangement of the rollers 21,22.
  • the forming zone 24 of the rolling stock 23 is again formed asymmetrically.
  • the rollers 21 and 22 are again formed differently large.
  • the roller 21 in this case has a smaller diameter than the roller 22.
  • the rolling arrangement of FIG. 3 also has an asymmetrical Walzgutauslauf 25 and an asymmetric Walzguteinlauf 26, in which the inlet 26 is inclined downward and the spout 25 is inclined up to the first roller 22. It can be seen clearly that the rolling stock 23 does not run horizontally through the rolling stand, but offset from the horizontal offset and runs. Also, the rolling stock at the outlet 25 has a curvature.
  • FIG. 4 schematically shows a representation 30 of two work rolls 31,32 that roll a rolling stock 33 with asymmetric rolling condition with symmetrical arrangement of the rollers 31,32.
  • the forming zone 34 of the rolling stock 33 is again formed asymmetrically.
  • the rollers 31 and 32 are formed substantially the same size.
  • the rolling arrangement of FIG. 4 also has an asymmetric Walzgutauslauf 35 and an asymmetric Walzguteinmoor 36, in which the inlet 36 is inclined downwards and the outlet 35 is coming from above inclined. It can clearly be seen again that the rolling stock 33 does not run horizontally through the roll stand, but rather moves in and out of the horizontal. A curvature of the rolling stock 33 at the outlet 35 is not available. This is achieved by the proper adjustment of the rolling parameters. As such rolling parameters, for example, the peripheral speeds of the work rolls can be adjusted accordingly.
  • FIG. 5 schematically shows a representation 40 of two mutually offset work rolls 41,42, which roll a rolling stock 43 with asymmetric rolling condition with staggered arrangement of the rollers 41,42.
  • the offset in the horizontal direction has the size R.
  • the forming zone 44 of the rolling stock 43 is again formed asymmetrically.
  • the rollers 41 and 42 are in this embodiment of FIG. 5 essentially the same size.
  • the rolling arrangement of FIG. 5 also includes a horizontal stock outlet 45 and a horizontal stock inlet 46, wherein the inlet 46 and the outlet 45 are aligned substantially parallel. A curvature of the rolling stock 43 at the outlet 45 is also not available. Again, the peripheral speeds of the work rolls are selected accordingly.
  • FIG. 6 schematically shows a rolling device 50, such as a rolling mill, in which in a stand 51, the rollers 52,53,54,55 are arranged with their sets of rollers 52,53 and 54,55.
  • a rolling device 50 such as a rolling mill
  • the rollers 52,53,54,55 are arranged with their sets of rollers 52,53 and 54,55.
  • an upper set of rollers 52,53 and a lower set of rollers 54,55 is provided, in each of which the work rolls 53 and 54 on both sides of the rolling stock 56, the rolling stock 56 roll and reshape.
  • the lower set of rolls is arranged substantially non-displaceably in the direction of the extent of the rolling stock 56, the rolls 54, 55 being mounted in their rolling bearings 57, 58.
  • the rollers 52, 53 of the upper set of rollers are advantageously arranged to be displaceable in the rolling direction or in the direction of the extent of the rolling stock.
  • the adjusting means 61 a, 61 b, 62 a, 62 b may have mechanical and / or hydraulic adjusting means. These are arranged on both sides of the rolling bearings 59,60 and serve to support the rolling bearings 59,60 in the stator 51 and the position adjustment of the rollers 52,53 in the rolling direction.
  • a mechanism 63 for mechanical adjustment of the upper rollers relative to the lower rollers and a bearing 64 for supporting the lower rollers can be seen.
  • the lower rolls may be displaceable and adjustable in the rolling direction.
  • the upper rollers and the lower rollers in the rolling direction can be displaced and adjustable.
  • both an operation of the roll stand can be made, in which the sets of rolls are not relatively shifted against each other in the rolling direction and continue to operate the rolling stand are made, in which the sets of rolls are shifted from each other.
  • the displaceable roller set 52, 53 at least two rollers, wherein adjustment means 61 a, 61 b, 62 a, 62 b are respectively disposed on both sides of the at least two rollers 52,53.
  • the adjusting means 61a, 61b, 62a, 62b are arranged substantially at the level of the respective roller 52, 53. It is in FIG. 6 to recognize that the center or the axis of the respective roller is approximately in the region of the corresponding adjusting means 61a, 61b, 62a, 62b, viewed in the direction perpendicular to the rolling direction.
  • FIG. 6 it is in FIG. 6 to recognize that the center or the axis of the respective roller is approximately in the region of the corresponding adjusting means 61a, 61b, 62a, 62b, viewed in the direction perpendicular to the rolling direction.
  • the displaceable set of rollers 52, 53 have a common roller bearing 59, 60 for at least two rollers 52, 53, the adjustment means 61 a, 61 b, 62 a, 62 b engaging substantially at the level of the respective roller against the roller bearing 59, 60 in the direction of considered perpendicular to the rolling direction.
