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 if only a change of the work roll set is to take place, then the lower roll and the upper roll of a work roll set with the associated chocks must be introduced into the change slide 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.
  • a roll changing device for six-roll roll stands has become known, which has advantages over the roll changing device according to BR-A-PI 7 602 387 in that chocks can be assigned to the rolls of the intermediate roll set, with respect to their dimensions need not be smaller than the chocks for the rolls of the work roll set.
  • This known roll changing device also offers no possibility of even changing the intermediate rolls if necessary.
  • the aim of the invention is to provide a roll changing device for six-roll rolling 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 carriage or carriage can be made to the current changing situation.
  • a roll changing device After loading the roll loading station with a work roll set and an intermediate roll set, a roll changing device with these features forms an autonomous system which is able to withstand any possible change situation, as far as change processes for the work roll set and the intermediate roll set are concerned. 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 slide or carriage are designed to be closed at the top and on the longitudinal 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 guide supports for the chocks of the upper intermediate roller can be extended and retracted relative to the longitudinal side walls.
  • the work roll receiving compartment of the roller loading station forms a cassette compartment in which the work roll set is aligned by means of a cassette.
  • this cassette can sit with the work roll set at the roll change level in the roll loading station and the work roll set can be moved by means of its chocks on slideways from the roll loading station or the cassette in the change carriage or carriage.
  • the support and guide strips for the chocks of the upper work roll are provided in the cassette in relation to the longitudinal side walls and can be folded out.
  • 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 for one work roll set each along the same route as 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 roll set to be aligned are placed on the two rolls of the work roll set, such that any of the vertical planes of the roll loading station are then brought in front of an empty receiving section of the interchangeable carriage or carriage and the aligned roll set is transferred horizontally from the roll loading station into this receiving section of the interchangeable carriage or carriage is, and that finally the roller set (s) in turn horizontally from the interchangeable slide or carriage into the rolling stand will result.
  • the order for loading the roller loading station with the Work roll set and the intermediate roll set can be set up as desired. This means that first a work roll set and then an intermediate roll set can be brought into it by crane work. However, a reverse procedure
  • the first-mentioned type of procedure is preferred. It makes it possible to load the change carriage or trolley with a work roll set before the roll loading station is equipped with an intermediate roll set. 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 backup roll set 2 consisting of two backup 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 usually takes place at greater intervals than the change of the intermediate roll set 3.
  • the change of the intermediate roll set is usually done 3 again carried out at greater intervals than the change of the 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 in various horizontal planes with spacing one above the other with strip-shaped guide elements, 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 the work roll set 4 and the intermediate roll set 3 relative to the six-roll stand 1 is effected by means of a special roll changing device 10, which is constructed next to the six-roll stand 1, namely on the side of the drive 11 facing away from it, as is the case that can be clearly seen in FIG.
  • the roll changing device 10 has a changing carriage or carriage 12 which can be moved along a roadway, namely on rails 13, relative to the six-roll stand 1 in the direction parallel to the roll 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 the latter.
  • the drive carriage 14 In addition to the travel drive for the reciprocating movement of the interchangeable carriage 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.
  • cassette carriage 15 there is a cassette 18 parallel to the rolling direction of the six along special travel rails 17 which extend essentially transversely to the travel rails 13 roller mill stand 1 arranged to be movable.
  • 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 long 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 section 18 'and 18 "of the cassette 18 is inside on the long sides with support and guide supports 19' and 19" for chocks 8 'and 8 "of the intermediate rolls 3' and 3" of an intermediate roll set 3 and 4, which are superimposed in four horizontal planes at predetermined intervals also equipped with support and guide supports 20 'and 20 "for the chocks 9' and 9" of the work rolls 4 'and 4 "of a work roll set 4.
  • support and guide supports 19' 19" and 20 '20 intermediate roller sets 3 and work roll sets 4 can be extended and retracted as required.
  • the receiving compartment provided for receiving the new work roll set 4 and intermediate roll set 3 to be inserted into the six-roll stand 1 can be used 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, in addition to the change carriage or carriage 12, with the equipment just explained as Another essential functional part is 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 stand 1 and the interchangeable carriage or carriage 12 when the latter is in its end position remote from the six-roll stand 1, as shown in FIG 1 is recognizable.
  • 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 is 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 serves 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 suitable for accommodating a work roller set 4 formed by a lower working roller 4 ′ and an upper working roller 4 ′′.
  • the receiving compartment 23 for the intermediate roller set 3 is designed to be open both upwards and towards the opposite end faces. The lower intermediate roller 3 'and the upper intermediate roller 3 "of the intermediate roller set 3 can therefore be loaded in succession from above.
  • the lower intermediate roller 3' is supported in the receiving section 23 of the roller loading station 21 by its chocks 8 'from stationary support and guide supports 25 worn, which are at the same height on a horizontal plane as the support and guide supports 19 'in the two compartments 18' and 18 "of the cassette 18.
  • the upper intermediate roller 3" is with its chocks 8 "on support and guide supports 26 in Receiving compartment 23 set down, which are also on a horizontal plane, at the same height with the support and guide supports 19 "in the two compartments 18 'and 18" of the cassette 18. (See Figs. 2 and 3).
  • the support and management support gen 26 So that the support and management support gen 26, however, the previous lowering of the lower intermediate roller 3 'with its chocks 8' on the support and guide supports 25 does not hinder, they are mounted relative to the longitudinal sides of the receiving compartment 23 of the roller loading station 21 about horizontal axes 27 and can be folded and folded by pressure medium cylinders 28 operated and locked.
  • An intermediate roller set 3 can thus be accommodated in the receiving section 23 of the roller loading station 21 and already aligned in the support position in which it is transferred from the roller loading station 21 into one of the receiving compartments 18 'or 18 "of the cassette 18 of the interchangeable carriage or carriage 12 and then out this is moved into the six-roll stand 1 when the roll is changed.
