Definitions

  • Both 12-roll stands and 20-roll stands have two sets of rolls with work rolls on the facing ends of the two sets of rolls, which limit the roll gap and act on the rolling material from two sides.
  • each set of rolls has a number of inner intermediate rolls and outer support rollers on which the work roll is supported.
  • the direct employment with 20-roll stands makes it possible to install work rolls with diameters of up to approx. 2.5, for example between 30 and 70 mm, without additional conversion measures and in particular without changing the number of rolls.
  • the type of roll stand e.g. Two, four or 20-roll stand.
  • multi-roll stands with 12 or 20 rolls and work rolls with a small diameter in order to economically, ie with as few passes as possible, from a relatively large initial thickness to a minimum final thickness of, for example, 0.01 mm or 0.05 mm to come and then subject the surface of the rolling stock to a subsequent rolling by passing the rolling stock through a roll stand with a relatively large roll diameter without any further change in the final thickness achieved with the multi-roll stand.
  • a 12-roll stand always works with 12 rolls
  • a 20-roll stand always works with 20 rolls. This means that in a first rolling process when a very small final thickness of a relatively thick starting material is reached in one pass, at most a few rolling passes and the need for surface finishing, two different roll stands must be used. First a multi-roll stand with, for example, 20 rolls, of which the work rolls are very slim for reducing the thickness of the roll stand, and then a roll stand with fewer rolls, the work rolls having a relatively large diameter.
  • the object of the invention is now to design a multi-roll stand so that work can be carried out with it as previously carried out on a 20-roll stand, but also work that requires a larger work roll diameter than possible with a 20-roll stand.
  • the object of the invention is to show a multi-roll stand which has the advantages of a multi-roll stand, for example has a 20-roll stand, but can be converted with simple means so that an economical use when rolling thicker strips or even use as a skin pass mill is possible.
  • a roll stand which is a 20-roll stand and can be used equally for all work for which 20-roll stands are provided; with which rolling material can be brought to a final thickness, for example at least in the range of 0.10 mm.
  • work can be carried out with the roller stand with almost the same efficiency, for which other roller stands have previously been used.
  • the training as a 20-roll stand with the larger number of rolls offers good conditions for the fact that when converting to sets of rolls with work rolls that have a larger diameter, such a number of support rolls remains in the stand that the remaining number of rolls still has enough of the work rolls Support larger diameter, that is, lower requirements for the support, but on the other hand so many support rollers can be removed that work rollers with larger diameters can be installed.
  • a roll stand with a much larger area of application is created. If the roll stand is equipped as a 20-roll stand, it can be used to optimally perform the rolling operations that are required when using today's 20-roll stands; in particular, rolling material can be rolled to the smallest final thickness in an optimal manner. There is no need to compromise on a 20-roll stand in standard construction. If the same roll stand is converted to a 14-roll stand with less effort, which proves to be not difficult to do in view of the situation described above, then almost the conditions are reached that are necessary for re-rolling. This means that hardly any compromises have to be made compared to a special finishing mill.
  • the area of application of the roll stand according to the invention can again be seen as expanded, in that the thicknesses in the range of 0.10 mm can be achieved in the equipment as a 20-roll stand, then the roll stand is converted to the 14-roll stand, and that beforehand with the very lean work rolls to the desired final thickness, which is easily possible with the 20-roll stand, by using the far less slender work rolls of the 14-roll stand without additional thickness reduction, which is adequately surface-treated for a whole range of applications.
  • a rolling mill must therefore do something with the purchase of a roll stand according to the invention Invest more than if only a 20-roll stand were purchased, but can cover the work area of two roll stand types with one machine, so that the solution according to the invention will ultimately represent the more economical solution.
  • Invest more than if only a 20-roll stand were purchased, but can cover the work area of two roll stand types with one machine, so that the solution according to the invention will ultimately represent the more economical solution.
  • it can be used to process rolling material that comes from only one machine according to the invention, where it is based on the currently customary technology comes from two different roll stands. It is therefore possible with the invention to solve the problem more economically from a number of points of view.
  • FIG. 3 shows a side view (partly in section) of an embodiment of the upper part of a roll stand (FIG. 3) or a cross-sectional view of this upper part (FIG. 4).
  • the roll stand is a stand construction with direct hydraulic adjustment.
  • the hydraulic adjustment is labeled 1.
  • the employment 1 has the advantage that due to the free in large areas selectable adjustment stroke within a certain limit, a minimum / maximum usable work roll diameter can be selected.
  • the limit is determined by the geometry of the two roller sets 2, 3. It can be implemented as a 20-roll stand with work roll diameter ratios of up to 2.8, as has already been achieved with known roll stands, which are designed exclusively as 20-roll stands and where work rolls 5, 5 'can be used, the diameter of which is between 30 and, for example Can be 70 mm.
  • the multi-roll stand according to the invention in the configuration according to FIG. 1 is designed as a 20-roll stand.
  • the hydraulic adjustment 1 is arranged at the top, which acts directly on the upper bearing housing 15 with the upper set of rolls 2, which in turn acts with the work roll 5 on the top of the rolling material 14 or limits the roll gap 14 'from above, and a work roll 5 'of a lower roll set 3 acts on the underside of the rolling material 14 or delimits the roll gap 14' from below.
  • the work rolls 5, 5 ', inner intermediate rolls 6, 7 or 6', 7 ', outer intermediate rolls 8, 9, 10 or 8', 9 ', 10' and support rollers 11 or 11 'of the upper roll set 2 or of the lower roller set 3 correspond to the state of the art, so that this only has to be dealt with in detail as it happens in connection with FIGS. 3, 4.
  • the bearing housings 15, 15 'of both roller sets 2 and 3 are arranged in the roller stand so as to be adjustable relative to one another in order to bring the lower support roller set 3 to pass-line height on the one hand and on the other hand to be able to open the roll gap 14 'to different degrees.
  • employment 1 or drives are designed; the rotary movement of the rollers or rollers is brought about by a drive which, like the employment itself, is customary and is therefore not shown.
  • rollers 5 to 10 or 5 'to 10' on the one hand and the rollers 11, 11 'on the other hand it should be pointed out that all the rollers 5 to 10 or 5' to 10 'are formed in one piece from one end to the other to form work rolls or intermediate rolls, while 11 and 11 'respectively refer to backup rolls, which, however, are not formed in one piece from one end to the other end, although they have a length corresponding to the work and intermediate rolls, but rather from individual rollers exist, which are associated with each other at relatively short intervals in a rotationally fixed manner a shaft 16, so that the support rollers 11, 11 'are referred to in practice as roller sets or support roller sets.
  • the roll stand can now be converted from a 20-roll stand according to FIG. 1 to a 14-roll stand according to FIG. 2.
  • the roller group 5 to 8 or 5 'to 8' of each roller set 2 or 3 is removed and in their place an individual work roller 13 or 13 'with a correspondingly larger diameter is stored in the respective bearing housing 15 or 15'.
  • the work roll 13 or 13 ' is supported on the rolls 9, 10 or 9', 10 '.
  • Essential to The invention is thus the coordination between the roller groups 5 to 8 or 5 'to 8' on the one hand and the work roll 13 or 13 'on the other hand in the respective roller set 2 or 3 and the possibility of their storage in lateral positions or bearing housings of the roll stand that in each of the two cases the work rolls act on the rolling stock 14 'in the roll gap 14 and their proper support is possible or guaranteed. So there are so many rolls that can be removed from the 20-roll stand that space is created for two rolls of large diameter.
  • rollers including the work rolls 5, 5 'from the roll stand according to the invention when it is initially equipped as a 20-roll stand that space is created for two work rolls 13, 13' of a correspondingly larger diameter. Nevertheless, there remain so many rolls in both sets of rolls 2, 3 that it is sufficient for the thicker and therefore less prone to bending work rolls 13, 13 '.
  • Fig. 3 designates the upper part or the upper housing of a multi-roll stand according to the invention, so that the roller set shown is the upper roller set 2 according to Fig. 1, 2, assuming that the multi-roll stand as 20-roll stand is set up according to FIG. 1.
  • the lower roller set 3 is therefore designed accordingly.
  • the set of support rollers consisting of the rollers 11 and the support axles 16 is supported on the bearing housing 15 by means of saddle pieces 17, the saddle pieces 17 being adjustable independently of one another by means of adjusting devices which, for example, each consist of a pair of wedges 22, 23, on the actuating part of which are supported on the housing 15 23 a piston-cylinder unit 24, 25 acts, the other adjusting part 22 being assigned to the respective saddle piece 17.
  • adjusting devices which, for example, each consist of a pair of wedges 22, 23, on the actuating part of which are supported on the housing 15 23 a piston-cylinder unit 24, 25 acts, the other adjusting part 22 being assigned to the respective saddle piece 17.
  • Such an adjusting device is assigned to each saddle piece, which works independently of the adjusting devices of the other adjusting pieces.
  • the lateral of the outer intermediate rollers 9, 10 are adjustably mounted on the bearing housing 15 by piston-cylinder units 18, 19, only the two units 18, 19 being shown for the lateral outer intermediate roller 9, but the other lateral outer intermediate roller 10 being mounted accordingly. Accordingly, the middle outer intermediate roller 8 is mounted on a piston-cylinder unit 20.
  • the piston-cylinder units 18, 19 and 24, 25 and 20 are articulated on the bearing housing 15.
  • the inner intermediate rolls 6, 7 are also articulated on the bearing housing 15 (not shown in FIG. 3); the work roll 5 is loosely inserted between the rolling stock 14 and the intermediate rolls 6, 7.
  • the work roll 13 can be suspended by means of a piston-cylinder unit, similar to the piston-cylinder unit 20.
