Definitions

  • the invention relates to a device for processing rollers mounted in roller stands via chocks with an associated with each roller, abrasive, relative to the roller mounted unit that can be adjusted against the roller.
  • Online grinding devices of this type are used, on the one hand, to be able to make rolling program plans more flexible and, on the other hand, to increase the times between the roll changes necessary for reasons of rolling wear.
  • Such grinding devices have become known from an article in "Mitsubishi Heavy Industries Ltd. Technical Review, Vol 29, No. 3 Oct. 1993, pages 171-176".
  • a number of massive, non-driven grinding wheels whose axis of rotation are arranged substantially perpendicular to the roll axis, are placed against the roll to be ground in such a way that the grinding wheel is set in rotary motion, but a relative movement always remains between the roller and the grinding wheels.
  • the rolling disks are set in oscillating movement in the axial direction of the roll.
  • a similar online grinding device has also become known in which the solid grinding wheels have been replaced by flexible grinding wheels and in which the grinding wheels are coupled to drives.
  • Both online grinding devices have the disadvantage that they require considerable space in the already scarce space of the roll stand.
  • all components of these grinding devices are above or below the belt inlet or belt outlet area of the scaffold, where they z. B. in the event of breakdowns of the tape.
  • the grinding devices are expensive and always in the way when changing the rollers.
  • roller-shaped brushes When rolling aluminum, it has already become known to arrange roller-shaped brushes parallel to the work rolls and to store them in the chocks. These brushes are used to clean the rollers. Editing such. B. However, grinding the rollers is not possible with these brushes.
  • the invention has for its object to provide a simple, inexpensive device for grinding rollers during rolling operation, which requires little space in the area of the strip inlet or strip exit side and does not interfere with the roll change.
  • a roll stored in the chocks is easy and inexpensive to create.
  • the adjusting device is not arranged in the area of the belt inlet or belt outlet and the entire belt grinding device is removed together with the chocks of the rollers when the roll is changed and can easily be inspected when removed.
  • roller is divided and supported elastically on a shaft, as claimed in claim 4, even better, smooth transitions on the ground roller body can be achieved.
  • the additional axial oscillation of the whole or of the divided roll according to claim 7 can further contribute to the homogenization of the roller contour.
  • the control device according to claim 10 ensures that the actual contour the roller can be optimally brought up to a target contour.
  • Fig. 1 shows work rolls 1, 2 and backup rolls 3, 4 of a four-high stand.
  • the work rolls 1, 2 are mounted in chocks 5, 6 and the support rolls 3, 4 in chocks 7, 8.
  • the chocks 5 to 8 are guided against each other in a stand.
  • rollers 9, 10 are also mounted, which can be moved to or away from the work rolls 1, 2 via guides, not shown. Adjusting cylinders 11, 12 ensure the employment. Only the rollers 9, 10 are thus provided in the area of the inlet of the belt 13, while the positioning cylinders 11, 12 are accommodated in the chocks 5, 6 outside this area.
  • control device 14 to which actual roller contour values are fed via actual value sensors 15, 16.
  • the setpoints are supplied via an input / storage unit 17.
  • the outputs 18, 18 ′, 18 ′′, 18 ′′ ′′ of the control device 14 operate on the setting cylinders 11, 12 and on rotary, not shown, Bending and axial sliding drives.
  • Fig. 2 shows the roller 9, which is guided in the chocks 5, 5 'of the work roll 1, not shown.
  • the roller 9 has a roller body 19 and a roller jacket 20 consisting of elastic packaging, into which the abrasive 21 is embedded.
  • the roller 9 is also assigned a rotary drive 22, also shown only by the active arrows, an axial displacement drive 23 and bending drives 24, 24'.
  • the roller 9 ' is divided into four sections which are supported on a shaft 25 which is rotatably mounted in the chocks 5, 5'.
  • the support takes place via elastic sleeves 26, 26 ', 26' ', 26' '', which allow slight pivoting movements of the roller sections on the shaft 25.
  • a driver 27 on the shaft 25 engages in grooves, not shown, of the roller sections.
  • Adjustment drives 11, 11 ', rotary drives 22, axial displacement drives 23 and bending drives 24, 24' are also provided here.
  • Coaxial shafts 29, 30, 31, 32 are mounted on the axis 28, which are individually connected via rotary drives 22', 22 '', 22 ''',22''''can be driven or braked.
  • the individual roller sections 19 ', 19'',19''', 19 ''' are connected to the shafts 29, 30, 31, 32 in a rotationally fixed manner by means of drivers (not shown).
  • Adjustment drives 11, 11 ', axial displacement drives 23 and bending drives 24, 24' are also provided here.
  • the storage of the roller sections on the shafts 29, 30, 31, 32 can of course also be done via elastic sleeves.
