Definitions
- the invention relates to a method and a device for changing roll sets in roll stands of a rolling mill with a plurality of roll stands, each of which has support and work roll sets, by supporting one another and then extending in the axial direction of a work roll set or a support roll set on the operator side into a roll workshop and then moving back and forth Installation of new roller sets.
- Such a roller set changing method is known from DE 43 21 663 A1.
- support plates which are supported on carriages and can be moved transversely to the roll axes are equipped with at least two pairs of rails arranged next to one another.
- the work roll sets themselves are mounted on rollers.
- pits are created, on the bottom of which there are extension rails for support roller sets.
- the pits are covered by flaps that also carry rails on which the work roll sets are extended or retracted. Neither the design with pits nor the laying of the rails over the pit is particularly cheap.
- the object of the invention is to propose a flexible method for changing the roller sets from selected roll stands and to adapt the method to the workflow in a roller workshop with little effort in terms of device technology.
- the object is achieved according to the invention in that the worn work roll sets, which have been removed by a number of separate transverse transfer carriages corresponding to the number of roll stands on the operator side, are successively transferred to the roll workshop by a single locomotive and from there the new work roll sets are moved back and forth are placed at alternating intervals on the respective cross transfer carriages between the roll stands and that after the operator side has been released by the cross transfer carriages after a removed, worn work roll set, the worn backup roll sets are extended and brought to the roll workshop by crane, serviced, transported back and reinstalled in the assigned roll stands become.
- the process first separates the change of the work roll sets from the change of the backup roll sets and is therefore more flexible.
- the method is also cheaper because of the lower effort.
- the method of operation can then be applied to individual roll stands and the changing of roll sets.
- a simplification of the known methods in coordination with the roller workshop and a time saving are achieved in that in a starting position in front of each roll stand the transverse sliding carriages are simultaneously set to the change distance, worn work roller sets are extended, the new work roller sets are retracted and the Move worn work roll sets from their cross transfer carriages via slide rails on the chock into the roll workshop, unload and a new work roll set is returned to the starting position.
- a further simplification is achieved in that, in the starting position, the worn work roll set is pulled onto the assigned one half of the carriage and that the new type coming from the roll workshop
- the set of rollers which corresponds to the changing distance in front of the roll stands, is pushed onto the other half of the wagon at a distance from the axis.
- a temporal and local selection of the roller sets to be changed and the roll stands affected by them can also be made by successively moving the transverse sliding carriages out of their defined roll stand installation or removal positions in the rolling direction. This can also create appropriate conditions for changing backup roller sets.
- One embodiment of the invention consists in that the spacings and the changing positions to an adjacent rolling stand between the transverse sliding carriages are repeatedly set precisely in each case by means of intermediate plates pivoted into the horizontal, and that the set changing distances are canceled when the intermediate plates and / or the connecting plates are pivoted or perpendicularized , This makes it easier to approach the retracted position of the work roll sets precisely in the roll stand.
- a further development is given in that a gap is created for changing the support roller sets by moving the transverse sliding carriages in front of a roll stand and a worn support roller set is removed by crane and a new, overhauled support roller set is retracted by crane. This means that movements of the means of transport for work roll sets and for backup roll sets can be coordinated with the work plans of the roll workshop.
- Another embodiment consists of the fact that empty transverse sliding carriages are moved and parked into a parking position at one and / or other end of the rolling train when the intermediate plates are pivoted away.
- the device for changing roll sets in roll stands of a rolling train with several roll stands is based on a state of the art which provides support and work roll sets, with a drive for transverse removal or installation of the roll sets, with rails for transverse sliding carriages in the foundation parallel to the rolling direction and connecting tracks are moved to a roller workshop, and the trolleys are connected to a drive.
- the object is achieved by means of a device according to the invention in that the transverse sliding carriages can be moved parallel to the rolling direction at distances defined between the roll stands on rails continuously laid in the foundation, which can be controlled by means of pivotable intermediate plates and that only one connecting track perpendicular to the rails in The roller workshop runs on which only one locomotive runs, to which a set of work rollers can be coupled and uncoupled.
- This makes cooperation with the roller workshop more flexible than before, some of the assemblies can be automated, and the expenditure on fixtures and equipment is relatively low.
- a desired saving of space in front of the rolling stands is achieved in that the intermediate plates can be swiveled up or down in the vertical or can be adjusted in the horizontal.
- the transverse sliding carriages which are pivoted into the horizontal and at the ends of a foundation pit and which can be swiveled in horizontally and are pivoted in a stationary manner, provide a continuous connection form a walk-in work surface.
- These modules can also be operated automatically, so that crane work is saved.
- connection plates which are mounted at the ends of the rails, which run parallel to the rolling direction, are arranged so as to be stationary and foldable, which allow all the transverse sliding carriages to be moved together with the pivotable intermediate plates by at least half of a transverse sliding carriage.
- FIG. 1 shows a roll mill with three roll stands in a side view
- FIG. 1A shows a roll stand with a work roll set and a backup roll set in the operating position
- FIGS. 2-9 show different phases of changing a work roll set in plan view
- FIG. 9A parking positions of the transverse transfer carriages
- FIG. 10 a plan view of the phase "swing intermediate plates" with return to the starting position of FIG. 2nd
- the rolling train 1 is formed, for example, from three rolling stands 2, 3 and 4. Each roll stand 2, 3, 4 each has a support roll set 5 in the operating position and worn work roll sets 6 with chocks.
- the work roll and backup roll sets 5, 6 have already been removed and are each located on a first transverse slide carriage 9, a second transverse slide carriage 10 and a third transverse slide carriage 11.
- the work roll sets 6 (or 6a) each consist of two by means of the chocks supported top and bottom rollers, as well as the backup roller sets 5 (not shown in the expansion phase).
- Fig. 1 is the Starting position 1a given, the roller change on the operator side 1 b.
- a worn work roll set 6 is identified from the side (FIG. 1) and from above in FIGS. 2-8, each with a cross in the drawing and as a new work roll set 6a without a cross.
- transverse sliding carriages 9, 10, 11 On the operator side 1b there is a number of separate transverse sliding carriages 9, 10, 11 which correspond to the number of roll stands 2, 3, 4 and which accommodate the new work roll sets 6a coming from a roll workshop 20.
- the worn-out work roll sets 6 are pulled out by means of work roll extension cylinders 8 and a locomotive 21.
- the movements of the individual transverse sliding carriages 9, 10, 11, which are each equipped with their own travel drive, take place on a single connecting track 14a to the roller workshop 20, the transverse sliding carriages 9, 10, 11 being moved by the rails 14 in the rolling direction 13.
- the further transport from the rails 14 to the connecting track 14a takes place via sliding strips on the respective chock.
- the method on the connecting track 14a is carried out with only a single locomotive 21.
- the transverse sliding carriages 9, 10, 11 are controlled by spacing means 7. After the operator side 1b has been released by the transverse sliding carriages 9, 10, 11, in each case after a worn work roll set 6 has been removed, the worn backup roll sets 5 can be extended and brought to the roll workshop 20 by crane, re-ground, brought back and into the assigned roll stands 2, 3, 4 can be reinstalled and locked.
- the movability of the transverse sliding carriages 9, 10, 11 on the rails 14 in the foundation pit 15a of the foundation 15 each secures a gap 12 (see also FIG. 9A) for removal or reinstallation of the support roller sets 5.
- the transverse sliding carriages 9, 10, 11 are set up with a right half for worn work roll sets 6 at changing distances 2a, 3a, 4a (with three roll stands) and with the other left half for new work roll sets 6a.
- the spacing means 7 consist of pivotable clear intermediate plates 7a.
- the intermediate plates 7a are relatively light and thin, so that a crane is not required for the manipulation.
- the work roll sets 6a as shown in FIGS. 2 and 3, have just arrived from a roll workshop 20 located at a distance.
- the work roll sets 6a are coupled to the locomotive 21 and transferred to the transverse transfer carriages 9, 10, 11.
- FIG. 2 also shows the starting position 1a in front of each roll stand 2, 3, 4, the transverse sliding carriages 9, 10, 11 being set by means of intermediate plates 7a pivoted into the horizontal.
- the worn work roll sets 6 are then extended (FIG. 3). After transverse movement on the other half of the carriage, the new work roll sets 6a are moved into the respective roll stand 2, 3, 4.
- the worn work roll sets 6 are then moved into the roll workshop 20 for maintenance.
- a new work roll set 6a is moved back to the start position 1a (FIG. 2), after which the cycle begins again.
- a special feature is that in the start position 1a the worn work roll set 6 is pulled onto the assigned half of the carriage and that the new work roll set 6a, which is set to the change distance 2a, 3a, 4a in front of the roll stands 2, 3, 4, on the the other half of the car is put on and an exact setting is already made.
- all new work roll sets 6a are in their installation position with respect to the roll stands 2, 3 4 and are by means of the work roll Entry cylinder 8 and the locomotive 21 inserted and then locked in the frame.
- the new work roll sets 6a are inserted into the roll stands 2, 3, 4 and locked in the operating position.
- the intermediate plates 7a which are pivoted into the horizontal in each case, are repeatedly set precisely in the distances and the changing positions to an adjacent rolling stand 2, 3, 4 between the transverse sliding carriages 9, 10, 11, with the fixedly mounted connection plates 18 at the ends the rails 14 close the remaining gaps.
- the distances between the transverse sliding carriages 9, 10, 11 can be eliminated by pivoting the vertical plates 7a and / or the connecting plates 18 up or down, as shown in FIG. 6.
- the transverse sliding carriages 9, 10, 11 successively reach a connecting position to the locomotive 21 on the connecting track 14a.
- the respective worn work roll set 6 is driven into the roll workshop 20 and replaced there by the new work roll set 6a.
- a worn work roll set 6 is driven into the roll workshop 20 by means of the locomotive 21, there in turn exchanged for a new work roll set 6 a and moved back again, which has already been done in FIG. 8.
- the second work roll set 6 has already been moved back out of the roll workshop 20 with a new work roll set 6a. Only the third worn work roll set 6 has to be driven into the roll workshop 20.
- the intermediate plates 7a are each individually articulated on a transverse sliding carriage 9, 10, 11 and are moved up or down with a pneumatic or hydraulic piston-cylinder drive 17 carried on the carriage.
- piston-cylinder drives 17 are arranged on the connecting plates 18 and double on the first transverse sliding carriage 9 and on one side, on the right on the second and third transverse sliding carriages 10 and 11.
- the transverse transfer carriages 9, 10 and 11 are each moved back to the expansion position in front of the roll stands 2, 3, 4 after loading with a new work roll set 6a according to FIG. 10. Subsequently, the intermediate plates 7a are raised in the horizontal and the connecting plates 18 are lowered in the horizontal. The new work roll sets 6a are thus prepared for a quick change of worn work roll sets 6 in position.
- the invention also allows the replacement of worn wear roller sets 6.
- 1, 2-5 and 10 are arranged at the ends of the rails 14, which run parallel to the rolling direction 13, the respective fixedly rotatably mounted and vertically adjustable connecting plates 18, which together with the intermediate plates 7a, the working surface 19th form.
