Furthermore, an associated method will be described.
  • WO 2005/089 972 A1 describes a method for changing sets of rolls in rolling mills of a rolling mill having a plurality of rolling mills, which each have supporting and work roll sets, by supporting one another and then extending in the axial direction of a set of work rolls or a support roller set on the operator side in a roller workshop and subsequent retraction and installation of new sets of rollers.
  • the number of separate transverse transfer cars transported on the operator side of the number of rolling mills are transported on a single connecting track following one another by a single locomotive into the roller workshop, from where the work roll sets are returned and at alternating distances to the respective transverse transfer carriage be set between the rolling stands and that after releasing the operator side by the cross slide each after a developed worn Häwalzen- set the worn support roller sets extended and brought by crane in the roller workshop, maintained, transported back and re-installed in the associated rolling stands. Further described is an associated device.
  • the invention has for its object to propose a flexible method for changing / transporting the sets of rollers in the rolling hall at device complexity and a device for performing the method according to the invention.
  • the invention also relates to a device for carrying out the method according to the invention.
  • the device is designed as a displacement platform, wherein the displacement platform is designed to run on two rails arranged in parallel, in order to accommodate both the first, used set of work rolls and the second set of work rolls.
  • the sliding platform is guided and stored horizontally even after the span / cover the roll change pit.
  • the work roll changing device is located on the operating side of the rolling mill.
  • the task of the work roll changing device is to pull used work roll sets out of the roll stand and, for example, subsequently to transport them to the roll workshop or to transport the newly ground work roll sets from the roll shop to the rolling mill stand.
  • the transverse displacement of the sets of rolls is arranged in the roll hall in the region of the roll change pit.
  • the task of the transverse shift is to move the used set of work rolls pulled out of the roll stand so far out of the roll center / center roll change pit until the new work roll set can be positioned in the roll center.
  • the sliding platform consists of a steel structure with the same sliding strips as on the platforms.
  • the sliding platform is designed so that two sets of work rolls - a used and a new set of rolls - can be positioned on it.
  • a hydraulic cylinder moves the sliding platform to the desired position.
  • the relocation platform itself is rail-bound. and runs in a preferred embodiment on a total of twelve rollers, which are each held in double-row thrust bearings.
  • the sliding platform according to the invention consists of a simple bridge and can be due to the rollers, by means of the hydraulic cylinder, drive laterally from the roll change pit at each backup roll change to release the entire width of the roll change pit.
  • the support roller set or the support rollers with the chocks can be transported without interference by the displacement platform by means of a locomotive from the rolling stand through the roll change pit in the rolling hall in the roll workshop. An assembly and removal of the sliding platform by the hall crane is eliminated. Furthermore, no space for the storage of the sliding platform in the rolling hall is needed. This leads to a high time savings.
  • Fig. 1 in cross section a rolling hall with a rolling mill and one of them separated by a wall roller workshop;
  • Fig. 2 as a detail a sliding platform in the rolling hall
  • Fig. 5 in plan view, the sliding platform in the right position for pulling out a support roller set.
  • a rolling hall 1 in the rolling direction and on the right side of a rolling mill 2 is shown on the left side. Both areas are separated by a wall 3.
  • a rolling mill 4 an upper and a lower support roller 5, 6 and an upper and a lower work roll 7, 8 are arranged.
  • a locomotive 9 is used for transport from the roll stand 4 in the rolling hall 2 into the roll workshop 2, for example, to reground the rolls.
  • a locomotive 9 is used for transport from the roll stand 4 in the rolling hall 2 into the roll workshop 2, for example, to reground the rolls.
  • This is located in a roll change pit 10, which connects the rolling hall 1 and the roll workshop 2. All devices such as rails, etc. are built on a foundation or several foundations11. The locomotive 9 can thus be moved from a waiting position 12 at the right end of the roll changing pit 10 to the rolling mill 4.
  • the roll change pit 10 is divided into a lower narrow area 16 and an upper wide area 17.
  • the lower narrow region 16 is only marginally wider than the locomotive 9.
  • the upper wide region 17 has platforms 20 at its two edges 18, 19. These are folded down when pulling or transporting a set of work rolls 7, 8 and have at their top guide rails 21 on which the set of work rolls 7, 8 can be moved.
  • the platforms 20 have a spacing which allows a coupling device 14 attached to the locomotive 9 on the upper side 13 to pass through. For transporting the larger diameter support roll set 5, 6, the platforms 20 are folded up, thus widening the passage.
  • FIG. 2 shows such a device.
  • the device also referred to as side shifting, provides that the removed set of work rolls, consisting of the work rolls 7, 8, and a new set of work rolls 22 can be arranged parallel to one another on a transverse displacement platform 23.
