Definitions
- a roll changing device for six-roll mill stands with such a generic design is already known from BR-A-PI 7602387.
- the structure and mode of operation of this known roll changing device are such that first, with the help of a crane, the individual rolls together with their chocks in one of the two adjacent compartments must be parked in a very specific order.
- the sequence of the transport and loading processes to be carried out with the crane is directly dependent on the extent to which the next roll change is carried out on the respective roll stand. So should if the work roll set only needs to be changed, then the lower roll and the upper roll of a work roll set with the associated chocks must be inserted into the change carriage or carriage by crane work.
- a disadvantage of the known roll changing device has also been found that it can only be used if the chocks of the intermediate rolls have smaller dimensions than the chocks for the work rolls.
- This known roller changing device also offers no possibility, if necessary, even a change of the intermediate roll.
- the aim of the invention is to provide a roll changing device for six-roll roll stands with the generic features a) to d), in which the work roll sets and intermediate roll sets required or intended for roll changes can be kept so wide that problem-free and short-term coordination of the new roller system to be driven in with the interchangeable slide or carriage can be carried out to the current changing situation.
- a roller changing device with these features forms an autonomous system after loading the roller loading station with a work roll set and an intermediate roll set. which is able to cope with every possible change situation, insofar as change processes for the work roll set and the intermediate roll set are affected. It is in fact possible to replace only the work roll set, the work roll set together with the intermediate roll set, but also, if necessary, only the intermediate roll set using the roll changing device.
- the receiving compartments of the interchangeable carriage or carriage are designed to be closed at the top and on the long sides, but are designed to be open on opposite end faces.
- the receiving compartments of the roller loading station are designed to be open both upwards and towards the opposite end faces.
- the support and / or guide supports for the one construction pieces of the upper intermediate roller opposite the longitudinal side walls provided and folded.
- a particularly expedient embodiment of the roll changing device can be achieved by providing a work roll warming-up station with a plurality of warming-up compartments arranged next to one another, each for a work roll set, on the same path with the roll loading station.
- This work roll heating station can be moved independently of the roll loading station, that is to say relative to this and to the roll loading station.
- a roll changing device proves to be particularly advantageous because, first of all, the roll loading station in a given vertical plane is fed successively on different horizontal planes with the lower and upper rolls of the intermediate roll set and also in at least one adjacent vertical plane together with those on different horizontal planes to one another and also to the Horizontal planes of the two Rolls of the intermediate rolls set to be aligned two rolls of the work roll set is then brought to any of the vertical planes of the roll loading station in front of an empty receiving section of the interchangeable carriage or carriage and the roll set aligned thereon is transferred horizontally from the roll loading station into this receiving section of the interchangeable carriage or carriage , and that finally the roller set (s) is or are transferred horizontally from the interchangeable carriage or carriage into the roll stand.
- the sequence for loading the roller loading station with the work roll set and the intermediate roll set can be set up as desired. Ie first a work roll set and then an intermediate roll set can be brought into it by crane work. However, a reverse procedure is also easily possible
- the first-mentioned type of procedure is preferred. It makes it namely possible to change carriage or carriages have a working set of rollers to feed, 'before the assembly of the roller charging station is preceded by an intermediate roller set or completed. After the loading of the roller loading station with an intermediate roller set has been completed, the receiving compartment for a work roller set that has already been freed up can then be filled with one again.
- Fig. 1 of the drawing shows a complete overview of a complete rolling mill for the final rolling of strip material.
- This strip rolling mill is equipped with a six-roll stand 1, which has a support roll set 2 consisting of two support rolls 2 'and 2 ", an intermediate roll set 3 formed of two intermediate rolls 3' and 3" and one consisting of two work rolls 4 'and 4 " Work roll set 4 is equipped.
- the six-roll mill stand 1 is also associated with the usual auxiliary machines, such as, for example, driving apparatus, strip reel, scissors or the like.
- All rollers 2 ', 2 "; 3', 3”; 4 ', 4 "of the three sets of rolls 2, 3 and 4 working together in the six-roll stand 1 are each stored and guided in the windows 5 of the roll stand 6 in the usual manner by special chocks.
- the stands 6 of the six-roll mill stand 1 act via their windows 5 in a conventional manner with the chocks which store and guide the rolls 2 ', 2 ";3',3" and 4 ', 4 "of the different roll sets 2; 3; 4 together that, if necessary, not only the work roll set 4 but also the intermediate roll set 3 and also the backup roll set 2 can be changed.
- the change of the backup roll set 2 normally takes place at greater intervals than the change of the intermediate roll set 3.
- the change of the Intermediate roll set 3 is again carried out at greater time intervals than the change of work roll set 4.
- the roll stands are in the windows 5 6 - on both sides of the roll plane - special guide elements 7 are provided in mirror image to one another, of which only one is shown in FIG. 1.
- These guide elements are equipped with strip-shaped guide elements in different horizontal planes, one above the other, at a distance, along which the individual rollers 3 ', 3 "of the intermediate roller set 3 and also the individual rollers 4' and 4" of the work roller set 4 are used for storing and guiding them Serve chocks alternately out of the roll stands 6 of the six-roll mill stand 1 or have them run into them.
- the chocks of the intermediate rolls 3 'and 3 "of the intermediate roll set 3 and the chocks of the work rolls 4' and 4" of the work roll set 4 are provided with reference numerals only in FIGS. 2 and 3.
- the retraction and extension of both of the work roll set 4 and of the intermediate roller set 3 for Sechswalzen- W alzge- Studst 1 relative is effected by means of a special roll changing device 10 constructed adjacent to the six-high rolling mill 1, namely at the the drive 11 remote from side thereof is how this can be clearly seen in FIG. 1.
- the roll changing device 10 has a changing carriage or carriage 12 which, along a carriageway, namely on rails 13, relative to the six-roll stand 1 in the direction pa is movable parallel to the roller axes between two predetermined end positions.
- the end position of the interchangeable carriage or carriage 12, which is removed from the six-roll mill stand 1, is indicated in FIG. 1.
- the interchangeable carriage or carriage 12 is in turn composed of a so-called drive carriage 14 and a cassette carriage 15 coupled at least to this.
- the drive carriage 14 In addition to the travel drive for the reciprocating movement of the interchangeable slide or carriage 12 along the rails 13, the drive carriage 14 also has at least the push-in and slide-out devices 16 for the work roll sets 4 and the intermediate roll sets 3.
- a cassette 18 is arranged on the cassette carriage 15 along special travel rails 17, which extend essentially transversely to the travel rails 13, parallel to the rolling direction of the six-roll stand 1 to a limited extent.
- the cassette 18 is equipped with two receiving compartments 18 ′ and 18 ′′ arranged next to one another, each of which is essentially closed at the top and on its longitudinal sides, but is completely open on opposite end faces.
- the overall height of the cassette 18 and thus of the two receiving compartments 18 'and 18 "corresponds at least to the height of a roll system formed from a work roll set 4 and an intermediate roll set 3 with the associated chocks, as can be clearly seen from FIG. 2.
- Each receiving compartment 18 'and 18 "of the cassette 18 is on the inside on the longitudinal sides with support and / or guide supports 19' and 19" for chocks 8 'and 8 "of the intermediate rollers 3' and 3" of an intermediate roller set, which are located one above the other in four horizontal planes 3 and also with support and / or guide supports 20 'and 20 "for the chocks 9' and 9" of the work rolls 4 'and 4 "of a work roll set 4.
- intermediate roll sets 3 and work roll sets 4 can be provided along the horizontal support and / or guide supports 19 ', 19 "and 20', 20" provided in the receiving compartments 18 'and 18 "of the cassette It is not only possible to extend and retract a work roll set 4 by means of its chocks 9 'and 9 "along the support and / or guide supports 20' and 20", but also a work roll set 4 can be extended and retracted together with an intermediate roller set 3, the chocks 8 'and 8 "of the intermediate roller set 3 then being displaceable along the support and / or guide supports 19' and 19".
- the new work roll set 4 and / or intermediate roll set 3 to be inserted into the six-roll stand 1 can be accommodated
- the intended receiving compartment 18 'or 18 ", according to FIG. 2, for example, the receiving compartment 18', can only be loaded in the horizontal direction with the relevant roller set or sets.
- the roll change device 10 comprises the change carriage or carriage 12 with the equipment just explained as a further, essential functional part, there is also a roller loading station 21, which can be moved on a road running essentially transversely to the rails 13, namely also on rails 22, and thus can be moved parallel to the direction of movement of the cassette 18 on the rails 17 of the cassette carriage 15.
- the roadway or the rails 22 for the movement of the roller loading station 21 is located in the area between the six-roll mill stand 1 and the interchangeable carriage or carriage 12 when the latter is in its end position remote from the six-roll mill stand 1, such as from Fig. 1 can be seen.
- the roller loading station 21 can be placed to the left in front of the change carriage or carriage 12 in its retracted position, in such a way that it can be used with any compartment 18 'and 18 "of the cassette 18 on the Cassette carriage 15 can correspond.
- the roller loading station 21 is provided with two receiving compartments 23 and 24 which are arranged next to one another at a distance and which are of different designs.
- the receiving compartment 23 is used to accommodate an intermediate roller set 3 consisting of a lower intermediate roller 3 ′ and an upper intermediate roller 3 ′′, while the receiving compartment 24 is used to accommodate one a lower work roll 4 'and an upper work roll 4 "formed work roll set 4.
- the receiving compartment 23 for the intermediate roll set 3 is designed to be open both upwards and towards the opposite end faces lower intermediate roller 3 'and the upper intermediate roller 3 "of the intermediate roller set 3 are loaded.
- the lower intermediate roller 3 ' is carried in the receiving compartment 23 of the roller loading station 21 via its chocks 8' by stationary support and / or guide supports 25 which are at the same height on a horizontal plane as the support and / or guide supports 19 'in the two compartments 18 'and 18 "of the cassette 18.
- the upper intermediate roller 3" with its chocks 8 is placed on support and / or guide supports 26 in the receiving compartment 23, which are also on a horizontal plane, and at the same height as the support and / or guide supports 19 "in the two compartments 18 'and 18" of the pocket 18 (see FIGS. 2 and 3).
