Definitions

  • the invention is directed to a device for preferably at least in pairs, in particular batchwise, handling and / or transporting back-up rolls and / or work rolls of a roll stand between the arranged in a rolling mill stand and a roll workshop and in the roll workshop, comprising a transverse to the rolling direction of the roll stand from the roll stand in the roll workshop running roll change pit with a locomotive as a moving device for at least a pair or a set of developed support or work rolls and in the roll workshop transverse to the roll change pit and this transverse and movable in or against the rolling direction of the roll stand roll change stand.
  • Roll stands for rolling steel slabs or steel sheets include, for example, a work roll set consisting of a pair of work rolls, and one support roll each above and one below a work roll. If the work rolls and / or the backup rolls are worn, they must be replaced.
  • various devices are known, by means of which the retracted from the rolling stand support rollers or work rolls are moved from the rolling hall in the roll workshop and in the roll workshop. Likewise, by means of such devices in the roll workshop refurbished sets of rolls are fed back to the respective roll stand as a ground new set of rolls.
  • the JP 52-133061 A discloses a mechanism arranged to perform a "side shifting" in a rolling hall on a rolling line, in which a scaffold carrying respectively a new and an old set of rollers is slidably mounted on a sliding platform by means of a bar parallel to the rolling mill in and against the rolling equipment. Furthermore, a car is transversely over a certain range on rails in one direction arranged perpendicular to the rolling direction movable in the rolling hall. Moreover, this document discloses a vertically raised and lowered floor area in the immediate area of a rolling stand.
  • a similar mechanism for a "side shifting" in a rolling hall reveals the JP 5 192704 A , Likewise reveal the JP 49 014984 B as well as the JP 53 146952 A in each case a device for the "side shifting" in a rolling hall, wherein the JP 53 146952 A discloses a roll change stand, which is arranged as part of a "side shifting" mechanism in a rolling hall on a rolling stand.
  • the US 4,510,781 A discloses in a rolling hall in and against the rolling direction parallel to this movable roll changing stands.
  • a device is known from EP 1 954 416 B1 known.
  • This known device comprises a roll change pit extending transversely to the rolling direction of the roll stand from the roll stand into the roll workshop.
  • this roll change pit is guided on rails traversing arranged in the form of a hydraulically powered locomotive.
  • On this locomotive on the one hand from the assigned roll stand built-up work roll set can be coupled and moved in the coupled state from the rolling hall in the roll workshop and later, if desired, back into the rolling hall to the rolling stand.
  • a supporting roll set of the rolling stand can be coupled to this traversing device and moved along the roll changing pit from the rolling hall to the rolling mill and, if desired, back again.
  • a roll change stand movable in the direction transverse to the roll change pit and in or against the rolling direction of the roll stand which can accommodate a plurality of sets of work rolls. This makes it possible to provide on the respective roll stand both a set of new work rolls still during operation of the rolling stand and to park a developed set of work rolls immediately after its removal in the roll workshop.
  • a disadvantage of this prior art is that the support rollers only on the same lanes, namely those of the roll change pit, retracted and extended. This means that a rolled-out from the rolling stand support roller or a retracted from the roll stand support roller set must first be removed with the help of a lifting device, such as a hall crane, from the roadway of the shuttle, so that the road is prepared for receiving new support rollers or a new support roller set , This raising and lowering of backup rolls or backup roll sets during the backup roll change is laborious and time consuming. This leads to longer Stützwalzen Acoustic Forum, which adversely affects the productivity of the rolling mill.
  • the invention is therefore based on the object to provide a solution that makes it possible to reduce the time required for a backup roll change and to simplify the backup roll change.
  • the roll change stand has two spaced apart in the rolling direction of the rolling stand to each other, in cross-section, in particular U-shaped roll receiving areas, each both bearing surfaces for receiving work rolls and bearing surfaces for the Include recording of support rollers and which are drivable by the movable in the roll changing pit locomotive.
  • the device for handling / handling and / or transporting removed support rolls and / or work rolls of a roll stand has a roll change stand which can be displaced or moved transversely to the roll stand and the roll change pit has a transverse displacement platform, so that this part of the changing device or roll changing device can move not only the work rolls, but also or additionally the support rollers transversely.
  • a reduction of the support roller change times and a simplification of the support roller change is achieved on rolling stands.
  • the invention provides that the roll changing stand is mounted so movable on the bottom of a pit, that in each case a roll receiving area in a loading and / or Verfahrposition Kunststoff Walzencicgrub- can be brought, in which the movable in the roll changing pit locomotive in the roll receiving area is movable.
  • the invention is characterized in a further development characterized in that the roll receiving areas are spaced such that in each case a pair or a set of stacked working and / or support rollers can be arranged side by side.
  • the roll receiving areas are spaced such that in each case a pair or a set of stacked working and / or support rollers can be arranged side by side.
  • the roll receiving areas are spaced such that in each case at the same time a pair or set of stacked working and / or support rolls can be arranged next to each other.
  • each roll receiving area a arranged on the working roll change level of the rolling mill upper bearing or Verfahr Scheme and arranged underneath on the Stützwalzencicclude of the rolling stand and the Verfahri the roll change pit lower bearing or Verfahr Kunststoff.
  • a support roller set on the lower task or travel area and to bring this roller receiving area into a traveling position with the roller changing pit, so that a locomotive movable in the roller changing pit can be coupled to the support roller set and out of the roller changing stand and along the roller changing pit can pull to the rolling stand.
  • the locomotive which is movably arranged in the roll change pit can be moved into the roll receiving area when the roll receiving area is in the moving or moving position or can be coupled to a support or work roll set arranged therein.
  • a respective back-up roll or work roll set or support or work rolls can be pushed back and forth between associated roll stand and the roll shop.
  • the roll changing stand In order to ensure the necessary Querverschieb sadness or Querverfahrhus the roll changing stand, the roll changing stand is mounted on the floor of a pit movable.
  • the ground level of the pit is formed below the bottom level of the roll changing pit is what the invention also provides.
  • the wheels that enable a method of the roller changing stand can then be positioned below the floor level of the roller changing pit, so that the lower supporting or moving area of the roller receiving areas still remains easily accessible from the roller changing pit.
  • the invention is characterized in that the roll change pit has a support cross-section receiving the Verfahrquerites. Due to this dimensioning, it is possible to move in and along the roll change pit a support roll set from the rolling hall in the roll workshop and back to move or transport /.
  • a rolling hall In a manner not shown is located in a rolling hall at least one rolling stand having rolling mill or rolling mill.
