Definitions

  • the innovation relates to a roll stand, in particular a four-roll stand for rolling out strip material cross-sections of different cross-sectional widths, in which the rolling cycle has to start with the largest cross-section width and to be completed with the smallest cross-section 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-PS 955 131 and DE-AS 22 06 912 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 conical tapering of their two end sections begins where the longitudinal edge of the strip material to be rolled came to rest on the work rolls.
  • the disadvantage here is that different intermediate rolls are required for strip material of different widths, which make expensive storage and frequent bearing changes necessary.
  • freeing is meant machining effected by turning, milling or grinding, which results in a diameter reduction of the work roll bale between 0.1 to 1.8 mm, preferably between 0.2 and 1 mm, in the case of unloaded rolls.
  • the new feature is now set itself the goal of becoming a rolling mill of the generic A rt to be established in which the Abtragsbearbeitung is accessible to the projecting beyond the respective cross-sectional width of the Harmonzenden strip material cross sections length fields of work roll barrels quickly and efficiently and with maximum accuracy.
  • At least one four-roll stand has to 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 1 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 supporting on the support roller 53 'or 53 "or 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" to be on their respective sides. Ends bent towards the roll gap 54.
  • each set of working rolls 52 is changed after the end of the rolling trip 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, before the work roll set 52 in question 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 the solid set of work rolls 52 with the two work rolls 52 'and 52 "is indicated as it is installed in the roll stand when changing rolls.
  • the roll balls 55' and 55" of the two work rolls 52 'and 52 designed for the rolling out of a strip material cross section 51 with the largest possible cross section width 56.
  • the length 57 of the roll body 55 'and 55 "to the work rolls 52' and 52 'substantially equal to the largest vorkotrmenden cross-sectional width 56 of the strip material cross-section 51, 55 have the roll barrel' and 55" virtually no rolling d ruck free end regions, the one Bend the roll ends in the direction against the roll gap 54 could cause.
  • 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 an amount which is at least 0.1 and at most 1.8 nm 1 - greatly exaggerated - indicated by dashed lines, the effective bale length 57 is thereby brought to a level 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 on the length range 58 against each other 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 broken 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 the pairs of grinding units 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 crossmember 62.
  • This traverse 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 high displaceable relative to the roll stands and also in their distance from the work roll axes to a predetermined starting diameter of the roll bales 55 'and 55 "of the work rolls 52'. and 52 "can be matched.
