Definitions

the invention relates to a multi-roll mill stand, the two work rolls of which are each supported directly or indirectly by a pair of axially adjustable intermediate rolls on support rolls or support rollers arranged in series, the intermediate rolls assigned to a work roll on one side of the roll stand and those of the other work roll assigned intermediate rolls on the other side of the roll stand each have a tapered roll bale end and the intermediate rolls assigned to the same work roll are independently adjustable such that the adjacent tapered roll bale ends of the intermediate rolls of the same work roll are axially offset from one another.
a known countermeasure in multi-roll stands in which the direct bending of the work or intermediate rolls known from other stands is not possible for structural reasons, is that Work rolls are not to be supported over their entire length via intermediate rolls, but only over a partial length, the partial length being adjustable.
each work roll is supported on a pair of intermediate rolls.
the intermediate rolls are in the same way tapered at one end, parabolic or otherwise, the tapered roll barrel ends of the intermediate rolls assigned to the different work rolls lying on opposite sides of the roll stand, while the tapered roll roll ends of the intermediate rolls assigned to the same work roll lie on the same side of the roll stand .
the support length can be adjusted as a function of the width of the strip to be rolled by axially displacing one pair of intermediate rolls and / or both pairs of intermediate rolls such that each edge of the rolled strip overlaps the tapered ends to a greater or lesser extent.
Such a multi-roll mill stand has proven itself in practice for many years; Nevertheless, the setting options for influencing the roll gap profile on such multi-roll rolling stands are sufficient, namely the pairwise axial displacement of the intermediate rolls with tapered roll barrel ends and the presetting of the bending line on two support rolls to achieve this Today's demands on the flatness of the band are often not sufficient.
the prior art also includes duo, quarto or six-high roll stands (EP 0 049 798 A2), the axially displaceable intermediate or work rolls of which have oppositely arranged, curved contours over the entire length of the bale and which are seamless in a certain axial position of the intermediate rolls complete.
Roll stands, the intermediate or work rolls of which have contoured roll bales, are intended to enable a uniform, continuous change in the roll gap profile over the entire length of the roll gap, the rolling strip in the edge region being influenced by the known method of roll bending possible here.
the invention has for its object to provide a multi-roll mill stand of the type mentioned, in which the support of the work rolls, in particular in the edge regions of the rolled strip, is adjustable to a greater extent than previously.
the support curve at the edges of the rolled strip by a more or less strong offset of the roll bale ends lying on the same side of the roll stand, taking into account their shape.
the work rolls Under the influence of the rolling force, the work rolls nestle against this curve.
a change in the setting position of one or both work rolls, the tapered roll barrel ends of which are assigned to the same edge of the rolled strip has an effect on the respective edge region of the rolled strip as a change in the roll gap profile.
This also provides a sensitive setting option to influence the flatness of the strip. Since the support curve for the work rolls not only includes the axial offset of the tapered roll bale ends, but also their contour, the roll bale ends assigned to the same strip edge have different tapering contours.
the support curve for the work rolls be influenced with independently axially adjustable intermediate rolls, but also in the area between the edge areas if, according to a further embodiment of the invention, an intermediate roll of each intermediate roll pair has a contour deviating from the cylindrical shape between the roller bale ends. Since the shape of the roll gap resulting from the rolling force results from the addition of the local diameter of the contoured intermediate rolls touching the work rolls at the same point, it is easily possible for the skilled worker in practice to choose the suitable dimensioning of the contour for the respective purpose.
each lockable intermediate roller is supported on the support rollers or the support rollers by at least one additional intermediate roller with contoured roller balls.
this configuration comparable effects can be achieved as with contoured roll bales for the intermediate rolls which directly support the work rolls.
the middle intermediate roller supporting an intermediate roller pair has the contoured roller bale
the outer intermediate roller supporting each of the intermediate rollers of each intermediate roller pair has the contoured roller bale.
each intermediate roller is arranged asymmetrically with respect to the center of the roller bale.
the two intermediate rolls with their asymmetrically contoured roll bales should be arranged in opposite directions. With such an arrangement, a relative axial displacement of the two intermediate rolls increases or decreases the curvature of the roll gap profile in the central region.
the asymmetrical contouring of the intermediate rolls is particularly suitable for multi-roll stands in which the support line cannot be preset on the support rolls, for example when the support rolls are solid.
Intermediate rolls with contoured roll bales can also be used with multi-roll stands, which offer the conventional setting option for back-up rolls.
the roll gap affects Effect of the axially displaceable intermediate rollers with the contoured roller bales then to bear when a rolling program is run in which the rolling forces are so low that the intermediate rollers and the axes of the support rollers are not deformed so much that the support saddles of the support rollers are fully adjusted to the preset Can support supports.
this embodiment of the invention is suitable for the stepless adjustment of the roll gap profile when dressing or re-rolling strips to a certain strength.
each work roll 1, 2 is supported on four support rolls 13 to 20 via a pair of intermediate rolls 3 to 6 and three further intermediate rolls 7 to 12.
the roll bales of each pair of intermediate rolls 3 to 6 are each tapered conically or parabolically at only one end of the bale. However, other taper contours are also possible.
the roll barrel ends 23, 24 have a different contour.
the intermediate rolls 3 to 6, the conical roll bale ends of which lie on the same side of the roll stand, should be diagonally opposite one another with respect to the rolling stock plane.
the intermediate rolls 3 to 6 which lie with their conical roll bale ends on the same roll stand side and therefore act on the same belt edge, are axially adjustable independently of one another, so that an axial offset can be set.
the intermediate rolls 33, 34, 35, 36 assigned to each work roll 31, 32 are designed differently. While the intermediate rollers 34, 35 have a cylindrical roller bale 37, 38 with a conical roller bale end 39, 40, the roller bales 41, 42 of the two remaining intermediate rollers 33, 36 are contoured over their entire length.
the contour of the roller bales 41, 42 is slightly parabolic, the largest diameter being outside the axial center. This asymmetry is in opposite directions in both roller bales 41, 42.
This contour of the roller bales 41, 42 naturally includes at least one tapered roller bale end 43, 44.
the roll profile in the strip center area can be curved to a greater or lesser extent.
the axial adjustment of the intermediate rollers 34 and 35 can be used to fine-tune the support curve at the strip edges.
the further intermediate rolls 7-12 contoured roll bales can correspond to the roll bales 41, 42 the intermediate rollers 33, 36 of the embodiment of Figures 3 and 4.
either the intermediate rolls 8 and 11 or the intermediate rolls 7, 9 and 10, 12 have a contoured roll barrel.
the work rolls directly support Intermediate rollers 3, 4 and 5, 6 are supported on an intermediate roller 7-12 with a contoured roller bale.
