Definitions

  • the subject of the invention is that of processes and installations for changing the rolls of a rolling mill.
  • Each end of a cage cylinder carries a chock integrating the bearings allowing the cylinder to be rotated about its axis.
  • the chocks are able to slide vertically in guide lights made in each of the uprights of the cage.
  • an equipped cylinder is a cylinder on which chocks have been mounted.
  • the used cylinders equipped with chocks are evacuated to the cylinder shop. Maintenance operators remove the chocks from the journals of each cylinder.
  • the cylinder workshop can be equipped with a device for extracting and reassembling the chocks of the type described in the document JP-A-63-220913 .
  • the active surface of the rolls is then repaired by machining on a grinding machine. After a step of checking the quality of the ground surfaces, the maintenance operators return the chocks on the roll pins which are then available to be brought near the rolling mill.
  • the cylinder change process as a whole is relatively slow.
  • the passage to the roll shop may deprive the operator of the possibility of quickly switching cylinders if necessary, for example to adapt the rolling mill to a change of production type. This is particularly true in some special applications where rolled quantities per campaign are relatively small.
  • the document US 4771626 discloses a cylinder changing installation comprising, on the operator side of the rolling mill, a carriage equipped with a chassis for changing a crew of cylinders and means for moving the cylinders called "push-pull" to load and unload the chassis of change a crew of cylinders.

  • the shuttle has a single exchange frame similar to that of the carriage.
  • the shuttle moves in a direction parallel to the rolling direction, between a position of cooperation with the carriage, the chassis of the carriage and the shuttle then being aligned for the transfer of used cylinders equipped from the carriage to the shuttle or cylinders equipped from the shuttle to the trolley, and a position away from the trolley travel area.
  • the installation also includes a rack and a second shuttle.
  • the rack is located away from the trolley travel area, on which the shuttle, also equipped with cylinder displacement means, deposits worn cylinders equipped and load new cylinders equipped.
  • the second shuttle is used to transfer equipped worn cylinders located on the rack to the cylinder workshop and the reverse in the case of new cylinders equipped.
  • the invention aims to overcome, for a large part, the aforementioned drawbacks through a new method of changing the rolls of a rolling mill and a clean installation to implement this method.
  • the cylinder change installation for carrying out this process should be able to be performed on existing rolling facilities. It is therefore necessary that the cylinder change installation satisfies congestion constraints compatible with existing rolling plants.
  • the installation is characterized in that it comprises at least one chock extraction device for coupling and uncoupling the chocks on the ends of cylinders aligned with the choke extraction device, and in that said shuttle device comprises first and second exchange frames, the shuttle device moving so that one or the other of the first and second exchange frame is alternately in alignment with the carriage replacement frame and with the chock extraction device.
  • the installation is fully automatic.
  • the chock extraction device is disposed on the shuttle device, and in that the shuttle device comprises a translation means for moving the first and second exchange frames relative to the extraction device. chocks.
  • the chock extraction device is located along the displacement rails of the shuttle device, on either side of the circulation path of the shuttle device.
  • the shuttle device comprises a number of exchange frame greater than one unit to the number of cages and trolleys of the rolling mill.
  • the shuttle device comprises a number of exchange frame equal to twice the number of cages and carriages of the rolling mill.
  • the shuttle device makes it possible to transport rolls from a roll changing zone near the rolling mill to a roll shop, and vice versa.
  • the distance D of the order of 10 m to 30 m separates the advanced position of the carriage from the retracted position of the carriage to allow to disengage the operator side of the rolling mill.
  • the choke extraction device being mounted on the shuttle device, the alignment of the first exchange frame or the second exchange frame with the choke extraction device consists in actuating translation means supporting the first and second exchange frame which is provided with the shuttle device.
  • the choke extraction device being disposed on either side of the shuttle device circulation path, the alignment of the first exchange frame or the second exchange frame with the Choke extraction device involves moving the shuttle device.
  • the shuttle device is moved to the cylinder workshop where the first exchange frame is emptied of used cylinders without chocks and the second exchange frame is loaded with new cylinders devoid of chocks, the shuttle device being again moved into the cylinder change zone in a standby position for the next cycle of cylinder change.
  • the method comprises the steps of, after inserting the new cylinders equipped with chocks in the cage, to move the carriage back to the retracted position, to align the first exchange frame of the shuttle device with the carriage replacement frame, to actuate the means of replacing the carriage cylinders to slide the worn cylinders of the first exchange frame in the carriage replacement frame, to set in motion the trolley to the cylinder workshop where the replacement frame is emptied of used cylinders without chocks and loaded with new cylinders devoid of chocks, to move the carriage to the cylinder change area near the rolling mill in its retracted position, to align the second exchange frame of the shuttle device with the carriage replacement frame, actuating the roll change means to slide the new rolls without chocks from the replacement frame to the second exchange frame to the next cycle of change of the rolls.

  • Such mounting devices are described, for example, in the document FR-9209477 .
  • the use of such coupling devices makes it possible to completely eliminate any human intervention for the operations of mounting and dismounting the chocks during the change of the cylinders. Knowing that such a change takes place in the immediate vicinity of the rolling mill, the fully automatable installation according to the invention is much safer.
  • the rolls of the various mill stands are generally replaced during a single roll stop. According to the state of the art, the replacement is done cage after cage. Indeed, replacements performed simultaneously on all the cages would pose significant risks to the safety around the rolling mill. According to the invention, it is accepted to increase the time required to replace the cylinders of a cage considered by adding the steps necessary for the exchange of chocks between the worn cylinders and new cylinders. However, the replacement of the rolls of the next cage can begin (steps of displacement of the corresponding carriage and extraction of the used rolls out of the next cage), while the steps of exchange of the chocks for the cage in question are in progress. Except for the iteration of the chock exchange steps for the last roll stand, the time required to perform the chuck exchange steps may be masked in a properly synchronized overall operation.
