Definitions

  • the invention relates to a system with a roll stand with a pair of work rolls for rolling a high-strength metal strip (e.g.: UHSS, AHSS) with four lateral support systems, which can be subjected to a support force directed in the direction of the work rolls by means of a force-generating device.
  • Each support system includes a support roller, roller bearings and at least part of a support beam.
  • the work rolls are supported in a direction perpendicular to the strip surface by intermediate and backup rolls.
  • the intermediate and preferably also the backup rolls are carried by a chock that can be pushed into the roll stand in the direction of its longitudinal axis and pulled out of it.
  • changing the rolls of the stand can be carried out more quickly and easily by moving the support systems from a rest position, in which they are arranged outside the area in which the chock of the intermediate roll moves when it is pushed in or pulled out, into an operating position are in which they are in contact with the work roll.
  • the support systems are moved out of the range of movement of the chock carrying the intermediate roll and, if necessary, the back-up rolls.
  • the chock with the rolls mounted therein can be removed from the roll stand, serviced and reinstalled independently of the back-up rolls be pushed in. It is also possible to service or replace the backup rolls independently of the chock rolls.
  • the usable diameter range (ground off range) of the work rolls is limited.
  • the minimum possible work roll diameter in conventional roll stands S 6-High TM roll stands
  • the object of the invention is to further develop a system with a roll stand of the type explained above in such a way that a larger diameter range (ground area) of the work rolls can be used than in the prior art, i.e. that work rolls with different diameters can be used in one roll stand, so that a wider range of steel grades, especially high-strength steels, can be rolled. Changing to other work rolls should be particularly easy.
  • this object is achieved by a system with a roll stand according to claim 1 .
  • the two work rolls are opposed to work rolls with a smaller diameter interchangeable, whereby only the four support systems have to be exchanged for support systems with smaller support roll diameters, without the need to change the support or intermediate rolls.
  • the diameter range of the work rolls is thus divided at least into two overlapping diameter ranges, with each diameter range being given a support system assigned to the diameter. This support system is then also changed when the work roll is changed, if the new diameter of the work roll makes this necessary due to a change in the diameter ranges.
  • support systems with smaller support rolls are then usually used.
  • the special arrangement of the support rolls allows high degrees of forming and thus high production rates, even when using the small roll diameters.
  • the two different support systems are preferably moved from the rest to the operating position by the same force-generating device, for example a hydraulically or pneumatically actuated actuating cylinder.
  • the force-generating device can also be a mechanically adjustable spindle.
  • the support beams are preferably divided into two detachably connected parts in the longitudinal direction of the support roller, the first part carrying the support roller and the second part being coupled to the force-generating device is.
  • the support roller carried by the respective support beam can be replaced particularly easily and quickly. This applies in particular when the part carrying the support roller is held on the second part of the support beam so that it can be displaced in its longitudinal direction.
  • roller bearings are arranged at regular intervals along the support roller.
  • the roll stand has two work rolls 1, 2 each.
  • the work rolls 1, 2 are each supported in the vertical direction via an intermediate roll 3, 4 on a backup roll 5, 6, the axis of rotation of which lies in the same plane as the axes of rotation of the work rolls 1, 2 and the intermediate rolls 3, 4.
  • the intermediate rolls 3, 4 are mounted in a chock 26, 27 and the back-up rolls 5, 6 in a separate chock 28, 29, while the work rolls 1, 2 are held loosely in the roll stand.
  • a roll gap W is formed between the work rolls 1, 2, in which a metal strip B conveyed in the conveying direction F is cold-rolled.
  • the chock 26, 27 is slidably mounted on a guide track, not shown, and can be pulled out of the respective roll stand in its longitudinal direction, parallel to the axes of rotation of the work, intermediate and back-up rolls.
  • Two support systems 30, 31, 32, 33 consisting of support rolls 8, 9, 10, 11, roller bearings 18 and parts 12b, 13b, 14b, 15b of a support beam 12, 13, 14, 15 are associated with each work roll 1, 2.
  • the work rolls 1, 2 are each supported on both sides by a support system 30, 31, 32, 33.
  • the support rollers 8, 9, 10, 11 are each carried by a support beam 12, 13, 14, 15.
  • the four supporting beams 12, 13, 14, 15 are divided into two parts 12a, 13a, 14a, 15a and 12b, 13b, 14b, 15b, the plane of division preferably being arranged vertically and extending parallel to the plane in which the axes of rotation of the work rolls 1, 2, the intermediate rolls 3, 4 and the Back-up rolls 5, 6 are.
  • the second part 12b, 13b, 14b, 15b of the respective support beam 12, 13, 14, 15 carries the support roller 8, 9, 10 or 11 assigned to this support beam 12, 13, 14, 15 Part 12a, 13a, 14a, 15a formed T - guide, the respective second part 12b, 13b, 14b, 15b is held on the first part 12a, 13a, 14a, 15a in its longitudinal direction so that it can be displaced with the support roller carried by it 8, 9, 10 or 11 can be pulled out of the respective roll stand.
  • roller bearings 18 are arranged at regular intervals on the support beams 12, 13, 14, 15 for lateral support of the support rollers 8, 9, 10 and 11 along the support rollers 8, 9, 10 and 11, respectively.

  • the axis of movement X of the pistons 20a, 21a, 22a, 23a are each arranged inclined in the direction of the roll gap W.
  • the respective second part 12b is pulled along the guide rail by the respective first part 12a of the support beams 12, 13, 14, 15 pulled. This can be done with the chock 26, 27 pulled out.
  • the support rollers 8, 9, 10, 11 with the support beams 12, 13, 14, 15 are moved into the respective free space so that the chock 26, 27 can be pulled out of the roll stand unhindered.
  • the supporting rolls 8, 9, 10, 11 can also be pulled out of the roll stand together with the chocks 26, 27.
  • the support beams 12, 13, 14, 15 are moved into a position in which their respective T-guide is arranged flush with the respective outer edge of the chock 26, 27 (see figure 1 ).
  • the chocks 26, 27 form an assembly and disassembly aid that makes it possible to dispense with a special auxiliary device of this type.
