Definitions

  • the present invention relates to a roll stand for producing a rolling stock, in particular a rolled strip, with work rolls, back-up rolls or intermediate rolls and back-up rolls.
  • Such a roll stand of the same type is described in EP-PS 0059417.
  • the known device is provided with a roller bending device, the chocks of the intermediate rollers being guided between blocks anchored in the stator windows and connected to the blocks by piston-cylinder units which can be acted upon on both sides and which are assigned to the blocks, and a guide piece on each block is guided vertically displaceably and the guide pieces are positively connected to the chocks by horizontal guides in the vertical direction.
  • a multiple use of this known roll stand for example as a reversing stand and / or skin pass mill, is not provided for according to the cited document, rather a separate skin pass mill would generally be used if required.
  • the device should be able to be easily adapted to different use variants. A trouble-free production process with still reasonable changeover times should be guaranteed without loss of quality for the rolled product.
  • the object is achieved according to the invention in that the intermediate rolls with their bearings and the associated slim work rolls are interchangeable with thick work rolls.
  • the roll stand according to the invention can be used both as a six-high reduction stand, and advantageously as a duo stand or as a four-high stand.
  • the intermediate roll bending block can advantageously be used as a new work roll bending block.
  • the interchangeable rollers are designed as a quick-change unit and are arranged in the stator windows.
  • a rolling mill operated as a single six-high reduction stand or reversing stand e.g. B. for the production of stainless steel strip with an initial thickness of about 8 mm to a final thickness of about 0.4 mm, can be used in a simple manner as a double skin pass mill in the same roll stand.
  • the intermediate and work rolls of the six-roll arrangement are replaced by a duo arrangement, an air gap remaining between the support rolls and the new work rolls.
  • the air gap between the work and backup rolls can simply be reduced to zero, so that the transfer of the roll forces then takes place directly between the support rolls and work rolls and not, as with the duo stand, via the chocks of the backup rolls onto the chocks of the Work rolls.
  • the work rolls can be replaced individually or together for a short time, the back-up rolls in turn remaining in the stand.
  • An advantageous embodiment of the invention provides that the chocks of the work rolls are provided with spacers with respect to the chocks of the backup rolls when used as a duo stand are, the chocks of the work rolls are fitted in guides that serve as guides when used as a sixth scaffold for the chocks of the intermediate rolls. Special holding or guiding devices can thus be omitted, which saves costs.
  • the spacers are designed as plates and are detachably connected to the chocks of the work rolls. This is a particularly simple and inexpensive measure to form an air gap between the work and backup rolls in the dual skin pass mill.
  • ⁇ lie one above the other form a spacer.
  • the total thickness of the spacers is adapted to the expected or approved roll wear, so that an air gap between the work and backup rolls is constantly maintained during operation of the roll stand as a duo rolling mill.
  • the spacers can be connected to the chocks in a form-fitting manner. This is a measure with which a particularly quick change or installation of the spacers can be ensured.
  • the work rolls have a bale contour which is curved differently in the direction of the two ends, in particular asymmetrical.
  • a Optimal influence on the roll gap in adaptation to the surface conditions of the rolling stock on the one hand and on the other to the roll wear.
  • the support rolls can have a bend contour which is curved differently in the direction of the two ends, in particular asymmetrical, whereby the roll gap is also influenced.
  • a particularly precise adaptation of the roll gap to the changing rolling conditions can be carried out.
  • the six-high mill stand shown has in the usual way two roll stands (1) arranged at a distance from one another, only one of which is shown in detail.
  • the roll stands (1) each have a stand window (2), in which two slim work rolls (3, 4) are received, which are supported on both sides by the support arms (5, 6; 7, 8) in a known manner.
  • the support rollers (10, 11) also located in the frame (1) or in the stand window (2) are, as is known, mounted in chocks (12, 13) at their ends. Between the slender work rolls (3, 4) and the support rolls (10, 11) there are intermediate rolls (14, 15) which in turn are held by their chocks (16, 17).
  • the insertion pieces (16, 17) for the two intermediate rolls (14, 15) are positively connected in the vertical direction, but are horizontally displaceable with the guide pieces (20 - 23) for the changing process.
  • the chocks (16, 17) of the upper and lower intermediate rollers (14, 15) are each assigned adjusting means (24 - 27) in the form of hydraulically actuated piston-cylinder units in the area of the blocks fixed to the stand.
  • These adjustment means or bending devices (24-27) for the intermediate rollers (14, 15) are each installed in the associated guide pieces (20-23). At the chocks (12) of the upper support roller (10) are attacked by the adjusting device (28) of the roll stand.
  • the rolling forces are first transferred in a known manner via the chocks (12, 13) onto the support rolls (10, 11), then at the points of contact of the support rolls (10, 11) with the intermediate rolls (14, 15 ) to this and from there to the work rolls (3, 4) or the rolling stock rolled in the rolling plane (29).
  • FIG. 2 shows the use of the roll stand as a double skin pass stand according to the invention
  • the chocks (30, 31) of the new thick work rolls (33, 34) with spacers (35, 36) with respect to the chocks (12, 13) of the support rolls (10, 11) are provided so that there is no contact between the bales of the support rollers (10, 11) and the bales of the thick work rollers (33, 34).
  • the chocks (30, 31) of the work rolls (33, 34) are fitted into the guide pieces (20 - 23) which serve as guides for the chocks of the intermediate rolls when used as a sex scaffold according to FIG. 1 (see FIG. 1, Chocks 16, 17; intermediate rolls 14, 15).
  • the intermediate roll bending block with the adjusting means (24-27) can advantageously be used as a new work roll bending block for crowning the work rolls (33, 34).
  • the spacers (35, 36) are designed as plates and are detachably connected to the chocks (30, 31) of the work rolls (33, 34), a plurality of plates one above the other forming a spacer (35, 36) can form.
  • the intermediate rolls with their bearings and the slim work rolls (cf. (5 - 8) are retracted hydraulically as far as possible to create space for the thick work rolls (33, 34) and their chocks (30, 31).
  • the chocks (12, 13) with the support rollers (10, 11) are moved apart via the adjusting means (24 - 27) and the new work rollers (33, 34) together with the chocks (30, 31) and the spacers ( 35, 36) moved into the stand window (2).
  • the adjustment means (24 - 27) are now released.
  • the rolling forces are transmitted via the chocks (12, 13), the spacers (35, 36), the chocks (30, 31) to the thick work rolls (33, 34).
  • the dual skin pass mill when the spacers are removed (cf. FIG. 2, numbers 35, 36), the dual skin pass mill can also be used as a four-high stand, in particular when transmitting rolling forces of more than 2000 t.
  • the rolling forces are then introduced directly between support rolls (10, 11) and work rolls (33, 34), i. H. without detour via the chocks (12, 13) and (30, 31).
  • the spacers can have any shape and can be divided not only horizontally but also vertically.
  • the respective structural design is left to the person skilled in the art in adaptation to the use.
