Definitions

  • the invention relates to a roll stand with two work rolls, each of which is optionally supported directly or via an intermediate roll on a back-up roll, the rolls of a pair of rolls being axially displaceable in opposite directions and each of the displaceable rolls being axially parallel over at least part of the length of the roll bale Straight, deviating, curved contour.
  • the curved contour extends over the entire length of the roll barrel and the contours of the two rolls of the pair of rolls complement each other only in a certain axial position of the rolls.
  • the invention relates to a further development of the roll stands according to patent 30 38 865 and relates to the design of roll stands of the type which, in addition to a pair of work rolls, has at least one pair of support rolls - four-roll stand - or which in addition to the pair of work rolls and the pair of support rolls The pair of intermediate rolls contains a six-roll stand.
  • rollers of a plurality of roller pairs of the roller set have an adapted curved contour on their roller bales and are thereby displaceable relative to one another.
  • support rolls and work rolls of the set of rolls have an adapted curved contour on their roll bales and at least the rolls of a pair of rolls are axially displaceable relative to one another and / or with respect to the rolls of the other pair of rolls.
  • support rolls, intermediate rolls and work rolls have an adapted curved contour on their roll barrel and at least the rolls of two pairs of rolls are axially displaceable relative to one another and / or relative to the rolls of the other roll pairs.
  • the four-roll mill stand 51 according to FIG. 1 has a set of rolls consisting of the pair of backup rolls 52, 53 and the pair of work rolls 54, 55.
  • the pair of work rolls 54, 55 delimits the roll gap 56 for the rolled strip 57.
  • the height of the roll gap 56 is thereby determined in the usual manner by adjusting devices (not shown) which act on the chocks of the support roller pair 52 and 53.
  • the roll balls 52 'and 53' of the support rolls 52 and 53 have a curved contour over their entire length, in such a way that in the case of the upper support roll 52 this contour is convex over the left half of the roll roll 52 'and over the right Half of the same is concave, while in the lower support roller 53 'it is concave over the left half of the roller barrel 53' and convex over the right half of the same.
  • Both sections of the roll barrel 52 'and 53' are determined by the same curvature curves and it can also be seen from Fig.1 that both support rollers 52 and 53 have an identical - here bottle-like - shape of the roll barrel 52 'and 53' and in the roll stands of the roll stand 51 are accommodated relative to one another in the installation position turned through 180 °.
  • the two work rolls 54 and 55 of the work roll pair also have roll bales 54 'and 55' with a contour that is curved over their entire length, this being designed to be complementary to the contour of the roll bale 52 'and 53' of the adjacent support roll 52 and 53, respectively.
  • the roll bale 54 'of the upper work roll 54 has a concave course over its left half and a convex course over its right half
  • the roll bale 55' of the lower work roll 55 has a convex curve over the left half and a concave curve over the right half.
  • the two work rolls 54 and 55 have an identical — in this case bottle-like — shape of their roll bales 54 ′ and 55 ′′ and are also accommodated in the roll stands relative to one another in an installation position turned through 180 °.
  • the roller gap 56 has a constant cross-sectional height over the entire bale length, although it runs slightly S-shaped.
  • the rolled strip 57 is therefore rolled out over its entire width with a uniform thickness.
  • a further influence on the shape of the roll gap 56 is, however, still possible in that a relative axial displacement of the work rolls 54 and / or 55 to the support rolls 52 and / or 53 is also carried out.
  • the pressure distribution between the roller bales 52 'and 54' and 53 'of the support roller set 52, 53 and the work roller set 54, 55, which are in contact with one another, can be influenced very sensitively, and thus the shape of the roller gap 56 can be further optimized.
  • the basic structure of the six-roll mill stand 61 according to FIG. 2 is the same as that of the four-roll mill stand 51 according to FIG. 1.
  • the set of rolls here does not only consist of the support roll pair 62, 63 comprising the two support rolls 62 and 63 and that of the two Work rolls 64 and 65 comprising work roll pair 64, 65, but there is additionally an intermediate roll pair 68, 69 consisting of the two intermediate rolls 68 and 69. Between the two work rolls 64 and 65 of the work roll pair 64, 65, the roll gap 66 for the rolled strip 67 is limited.
  • the contours, which are each convex over one bale half and concave over the other bale half, are on the roller bales 62 ', 68', 64 'and 63', 69 ', 65' of the support rollers 62, 63, the intermediate rollers 68, 69 which are in contact with one another and the work rolls 64, 65 are coordinated with one another such that they complement one another in the central axial position of all the roll pairs of the six-roll stand 61 according to FIG. 2.
  • the roll gap 66 for the rolled strip 67 therefore, despite its slightly S-shaped cross-sectional shape, has the same height over its entire length.
  • the contour of the nip 66 can then be delicately influenced by the additional presence of the intermediate roller pair 68, 69 even more sensitive than in the case of the four-roll stand 51 according to FIG. 1.
  • the support rolls 62 and 63 of the support roll pair 62, 63 as well as the work rolls 64 and 65 of the work roll pair 64, 65 and finally the intermediate rolls 68 and 69 of the intermediate roll pair 68 and 69 have identical - bottle-like shape of the roll bale and are accommodated in the roll stands of the roll stand relative to one another in each case in an installation position turned through 180 °.
  • six-roll stands 71 and 81 can also be varied with respect to the design of their roll set compared to the design according to FIG. 2.
  • the support rollers 72 and 73 of the support roller pair use roller bales 72 'and 73' of cylindrical shape over their entire length or conventionally spherical in shape, the work rollers 74 and 75 of the work roller pair 74, 75 and the intermediate rollers 78 and 79 of the intermediate roller pair 78, 79 equipped with roller balls 74 ', 75' and 78 ', 79', which have a curved contour over their entire length.
  • the work rolls 84 and 85 of the work roll pair 84, 85 roll bales 84 'and 85' have a cylindrical or conventionally spherical shape over their entire length.
  • the roll balls 82 ', 83' of the support rolls 82 and 83 and the roll balls 88 'and 89' of the intermediate rolls 88 and 89 are provided with a contour that is curved over their entire length.
  • the influencing of the roll gap 86 for the rolled strip 87 takes place here through the axially displaceable arrangement of the support rolls 82 and 83 and / or the intermediate rolls 88 and 89, while the work rolls 84 and 85 are axially immovable in their chocks.
