Definitions

  • the invention relates to a roll stand, in particular a four-roll roll stand for rolling out strip material cross sections of different cross-sectional widths, in which the rolling cycle has to begin with the largest cross-sectional width and must be completed with the smallest occurring cross-sectional width and in which the support lengths for the bales of the work rolls are at least approximately the same the respective cross-sectional width of the strip material cross-sections is adjustable.
  • DE-C-995131 and DE-B-2206912 make it part of the prior art to use roll stands in which the work rolls on intermediate rolls and these in turn rest on support rollers and the intermediate rollers are tapered at their ends.
  • the intermediate rolls are designed on the one hand so that the tapered tapering of their two end sections begins where the longitudinal edges of the strip material to be rolled come to rest on the work rolls.
  • the disadvantage here is that different intermediate rolls are required for strip material of different widths, which necessitate complex storage and frequent bearing changes.
  • the work roll bales are freed in their length ranges projecting beyond the respective rolling stock width by abrasion on the circumference of the bale - against each other and also against the backup rolls or intermediate rolls adjacent to them.
  • the length ranges of the work roll bales protruding beyond the respective rolling stock width are processed in the rolling stand, either in the final phase of a rolling process or during a very short interruption of the rolling process when the larger to the next smaller strip is to be rolled.
  • free-standing means a machining effected by turning, milling or grinding, which results in a diameter reduction of the work roll bale between 0.1 and 1.8 mm, preferably between 0.2 and 1 mm, in the case of unloaded rolls.
  • the object of the invention is now to provide a roll stand of the generic type in which the removal machining can be carried out quickly and quickly and with the greatest accuracy at the length regions of the work roll bales which extend beyond the respective cross-sectional width of the strip material sections to be rolled out.
  • At least one four-roll mill stand must be used, as is shown schematically in FIG. 1. It has a work roll set 52 consisting of two interacting work rolls 52 'and 52 "and a support roll set 53 consisting of two support rolls 53' and 53".
  • the work rolls 52 'and 52 "which are prevented from bending are strongly pressed over the respective cross-sectional width 56 of the strip material cross-section 51 to be rolled out, as a result of which they are in these areas flatten on their circumferential section which is supported on the support roller 53 'or 53 "above but on the intermediate roller.
  • the length regions of the work rolls 52 'and 52 "projecting beyond the respective cross-sectional width 56 are free of rolling pressure, so that they are not flattened and thus retain their circular cross-section. However, this causes the work rolls 52' and 52" at their ends against the roll gap 54 bent down.
  • each work roll set 52 is changed after the end of the rolling cycle and the roll bales 55 'and 55 "of the individual work rolls 52' and 52" by a mechanical removal process, for example by turning, milling, grinding or other suitable processes in their diameter , preferably between 0.2 and 1.0 mm, can be reduced before the relevant work roll set 52 is reinstalled in the roll stand for the next rolling trip.
  • a mechanical removal process for example by turning, milling, grinding or other suitable processes in their diameter , preferably between 0.2 and 1.0 mm
  • Fig. 1 solid lines indicate the work roll set 52 with the two work rolls 52 'and 52 "as it is installed in the roll stand when the roll is changed.
  • the roll balls 55' and 55" of the two work rolls 52 'and 52 are for the rolling out of a strip material cross-section 51 with the largest possible cross-sectional width 56. Since the length 57 of the roll bales 55 'and 55 "on the work rolls 52' and 52" is approximately equal to the largest cross-sectional width 56 of the strip material cross-section 51, the roll bales 55 'and 55 "practically no rolling pressure-free end areas which could cause the roll ends to bend in the direction toward the roll gap 54.
  • this removal process is brought about by grinding in such a way that the length regions 58 of the roll bales 55 ′ and 55 ′′ projecting beyond the respective cross-sectional width 56 of the strip material cross section 51 are reduced in diameter by a dimension which is at least 0.1 and at most 1.8 mm 1 - greatly exaggerated - indicated by dashed lines, the effective bale length 57 is thereby brought to a size approximating the cross-sectional width 56 of the strip material cross-section 51, while at the same time the end regions of the roll bales 55 'and 55 "of both work rolls 52 'and 52 "of the work roll set 52 are each exempted from each other on the length range 58 and also against the bales of the adjacent support rolls 53' and 53" of the support roll set 53, as is also made clear by the dashed lines in FIG. 1.
  • FIG. 2 of the drawing shows that the device assigned to the upper work roll 55 ′ and the lower work roll 55 ′′ are basically constructed and arranged in the same way.
  • the adjustment of the grinding units 59 and 60 or of the grinding unit pairs in the direction of the roller axis takes place via a feed drive 61 which is located together with the pair of grinding units on a cross member 62.
  • This cross member 62 is in turn fastened to the guide rings 63 which are rotatably mounted concentrically to the support roller axis in the roller stands or the support roller chocks guided therein.
  • control shafts 65 with the support roller and / or work roll chocks are at least vertically displaceable relative to the roll stands and furthermore in their distance from the work roll axes to a predetermined output diameter of the roll bales 55 'and 55 "of the work rolls 52' and 52 "can be tuned.
