Definitions

  • the invention relates to a rolling device according to the preamble of claim 1.
  • Rollers are well known in the art.
  • such rolling devices are known in which a pair of work rolls are acted upon by at least two opposite the work rolls larger support rollers for receiving the rolling forces, wherein at least one support roller acts on a work roll.
  • Such an arrangement is disclosed, for example, in JP 60154804 or by DE 2547490 A.
  • rolling devices in which the work rolls are acted upon by two substantially juxtaposed rolls.
  • Such rolling devices are known for example from US 1614425 or DE 35 37 153 A1.
  • WO 2007/051369 A1 discloses a rolling device in which the work rolls are supported by two support rollers, which are arranged fixed in a support element.
  • BESTATIGUNGSKOPIE A disadvantage of these rolling devices is that the support rollers are formed as one-piece rollers and thus not arbitrarily good influence in their roll bending bar or the support rollers are designed as multi-part rollers, the individual support roller parts are not independently controlled, so that the roll deflection is not targeted can be varied.
  • massive one-piece backup rolls have the disadvantage that they are less obtainable in the market as composite backup rolls.
  • a rolling device according to the features of claim 1 with a rolling device, which is characterized in that each of the first and second support rollers together form a group of support rollers that at least one of the groups is provided for supporting the work roll; and that at least one of the groups of back-up rolls is associated with a loading cylinder for setting the back-up rolls to the work roll.
  • first support rollers are characterized in that they are arranged substantially axially to a first support roller axis.
  • All so-called second support rollers are also characterized in that they are arranged at least approximately axially to a second support roller axis, wherein the first support roller axis and the second support roller axis but do not coincide, but as described in claim 1, viewed in cross section - with the axis the stripper forms a triangle.
  • the present invention provides to arrange a plurality of short support rollers distributed over the length of the work roll. Such short back-up rolls are much easier to produce than back-up rolls that extend the full length of the work rolls.
  • each group of first and second support rollers enables a local application of force to the work roll and thus a targeted local bending thereof.
  • an individual force distribution or roll bending along the entire length of the work roll is thus possible.
  • each group of support rollers is assigned in each case an admission cylinder, so that the groups of support rollers can each be actuated independently of one another.
  • first and second support rollers are assigned to a group of support rollers in such a way that the loading of the work roller through the first and the second support rollers is substantially the same.
  • the number of backup rolls per backup roll type multiplied by the width of the backup roll type, viewed in the axial direction, is substantially equal to approximately the same for each backup roll type of a group.
  • the loading cylinder is supported, on the one hand, on the support rollers and, on the other hand, on a substantially rigid cross-member. Furthermore, it is expedient if the loading of the support rollers of a group by the loading cylinder from group to group can be designed variably.
  • the traverse is held displaceable in a scaffold.
  • FIG. 1 is a schematic representation of a rolling device in a front view
  • Fig. 2 is a schematic representation of a rolling device in frontal views
  • Fig. 3 is a schematic representation of the rolling apparatus of Figure 1 in a side view.
  • FIG. 1 shows schematically a view of a rolling device 1 with a work roll 2.
  • the work roll 2 is, as is known typically provided twice, to a working gap 3 between the two work rolls 2 a To process rolling stock.
  • Figure 1 shows schematically a view of a rolling device 1 with a work roll 2.
  • the work roll 2 is, as is known typically provided twice, to a working gap 3 between the two work rolls 2 a To process rolling stock.
  • Figure 1 shows schematically a view of a rolling device 1 with a work roll 2.
  • the work roll 2 is, as is known typically provided twice, to a working gap 3 between the two work rolls 2 a To process rolling stock.
  • Figure 1 shows only one work roll 2 in Figure 1, wherein a second work roll 2 is drawn only indicated.
  • the rolling device 1 is symmetrical with respect to the roll gap 3, as shown in FIG.
  • the reference numerals for the same elements are marked accordingly.
  • the two work rolls are designated 2 and 2 '.
  • the work roll 2 is supported by support rollers 4, 5 which, viewed in the direction of the axis 17 of the work roll 2, are arranged next to each other.
  • the support rollers 4, 5 are arranged in groups 16, with a support roller 5, for example, being arranged adjacent to each other by two support rollers 4.
  • FIG. 1 shows four such groups 16. It is also noticeable that the support roller 5 is wider in its extent in the axial direction than the support rollers 4.
  • the number of support rollers 4 and their width may well vary, and the number of support rollers 5 and the width thereof may also vary.
  • the back-up rolls 4, 5 may be arranged in a different order.
  • the number of arranged support rollers 4,5 vary, which can be made dependent on the length of the work roll 2, for example.
  • a wide support roller 5 is provided in each case, which is supported on one side on the work roll 2 and two approximately half as wide support rollers 4, which is supported on the other side of the work roll 2. This advantageously ensures that the surface pressure and / or the loading on both sides of the work roll 2 are substantially equal.
  • the support rollers 4, 5 for the upper work roll 2 are provided above or resting on the same above.
  • the axis 6 of the first support rollers 4 and the axis 7 of the second support rollers 5 each extend parallel to the axis of the work roll.
  • the axes 6 and 7 are spaced from each other, but their distance is preferably smaller than the radius of one of the support rollers 4 or 5. This can be seen particularly well in Figure 3, which is a side view the arrangement of Figure 1 shows.
  • the work roll 2 is supported by two rows 10, 11 of support rolls 4, 5, more precisely by a row 10 of first support rolls 4 and by a row 11 of second support rolls 5.
  • the work roll 2 is supported both in the horizontal direction and in the vertical direction.
  • a loading cylinder 12 is provided in each case in a group of support rollers 4, 5, which acts on the support rollers 4, 5 and which between the support rollers 4 , 5 and a traverse 13 of a scaffold 14 and the device is arranged.
  • the loading cylinder 12 is a so-called hydraulic AGC cylinder, which tends to engage the support rollers 4, 5 of a group 16.
  • AGC stands for automatic gain control.
  • the respective charge cylinders 12, such as AGC cylinders, can be arranged above and / or below the two rows of support rollers 4, 5. This can be made dependent on which requirements are placed on the product to be processed.
  • the traverse 13 is a solid, rigid and possibly also heavy element to which the loading cylinder 12 attached are.
  • the cross member 13 can be adjusted to the frame 14 by means of adjusting means 15. It is advantageous if by means of the adjusting means 15, the traverse 13, for example, in dependence on the roll grinding and / or the adjustment of the rolling height and / or the rolling thickness is adjustable. In a lower arrangement of loading cylinders 12 ', this may also be the case that the adjustment of the traverse 13' can take place via the adjusting means 15 '.
  • a negative or positive roll bending of the roller 2 can be predetermined and adjustable, which is adjustable in the current rolling process.
  • a parallel work roll 2 or a roll with curved profile or a so-called CVC plus roll can be used, as has become known, for example, in WO 2002/009896, the Content is expressly included in the disclosure of the present application.
