专利摘要:
The invention relates to rolling production, specifically to means of rolling strip in cages with back-up rolls. The purpose of the invention is to reduce the transverse thickness variation of the rolled strip. The shape of the barrels of workers 17 and 19 and the supporting 13 and 15 rolls is such that half of the barrel of each valia is outlined convex, and half - with a curved curve. In this case, the profiles of the upper and lower sets of rolls are mutually rotated by 180. Each swath has an autonomous, drive 22 axial movement. The strip 24 is rolled in a curved gap between the rollers, the height of which is constant across the width. If it is necessary to fine-tune the distribution of the thickness of the strip along its width, the complexes of the rolls (upper and lower) in the axial directions mutually shift, thereby changing the gap. An additional mutual displacement of the work roll relative to the corresponding support roll is also possible. The invention can also be used in six-roll cages with intermediate support rolls. 12 il. W nr-V-t-H 23 3015 19 D DHYP: TchTs / I j- rt con ated yu

Figure 1 shows the rolling stand 140 is curved, while in the mill with four rolling rolls, which is a support roll 15, the left half of the barrel
The frame has beds 2 and 3. Beds 2 and 3 are connected to each other with the help of the upper rigid cross member 4 and the same lower cross member 5. In each of the beds 2 and 3, the top 6 and bottom 7 of the support roll cushion are installed. Also, the upper 8 and lower 9 cushions of the work roll, which can be displaced in the vertical direction. With the help of adjusting devices 10 for setting the rolls and spacers 11, it is possible to exert force on the pillows 6-9.
In the pillows 6, the trunnions 12 of the upper support roll 13 are installed, in the pillows 7 - the trunnions 14 of the lower support roll 15, in the pillows 8 - the trunnions 16 of the upper work roll I and in-:
The pans 18 are pins 18 of the lower work roll 19, and these pins are rotating. The elongation of the pins 12 and 14 for the base 3 of the rolling stand provides a connection with a rotating drive (not shown).
On the base 2, the traverse 20 is fastened; the extension in cross section 17 and 19 can be moved in the axial direction.
The gap 21 between the rollers is limited by the working rollers 17 and 19. In the gap 23, the height of which is controlled by the roller adjusting device 10, there is a bilge material (strip) 24.
The rolls 13 and 17 form the upper set 25, while the lower set 26 consists of rolls 15 and 19. The rolls of the same designation, i.e. Both work rolls 17 and 19 and both support rolls 13 and 15 in each case constitute a corresponding pair of rolls. All rolls 13, 15, 17 and 19 are profiled. Barrels 27-30 of these rolls have an axisymmetric curvilinear contour about the center.
The contour of the upper support rolls 13 passes along the left half of the barrel of the rolling roll 27 is convex, along the right half of the roll of the rolling shaft

rolling roll 28 has a concave shape, and the right half of it - a convex-vaulted shape. Both sections of the drums 27 and 28 are outlined with the same curves, and (Fig. 1) both supporting rolls 13 and 15 have the identical (in the form of a bottle) shape of the drums 27 and 28, and in the beds 2 and 3 of the rolling stand 1 they (original position) mutually rotated 180.
Work rolls 17 and 19 have barrels, respectively, 29 and 30 s. contour, curved along the entire length, while it is designed in addition to the contour of the barrel 27 or / and 28 of the adjacent support roll 13 or 15. In accordance with this, the barrel 29 of the upper work roll 17 has on its left half

the concave shape, and in its right half, the convex shape, while the barrel 30 of the lower work roll 1 has convex lines in its left half, and the curved concave shape in the right half. Both working rolls 17 and 19 (figure 1) have the identical (in the form of a bottle) barrel shape and, in the initial position, are mutually rotated by 180 in beds 2 and 3,
Rolls 13, 15, 17 and 19 are shown in their middle axial position. The gap 23 between the rollers along the entire length of the barrel has a constant height and the shape in the form of a letter S. Therefore, the rolled material 24 is rolled across its entire width with a uniform thickness.
2, the roll sets 25 and 26 are shown displaced with respect to each other. The gap 23 between the rollers in the middle of the rolled material 2 is smaller compared to the gap between the rollers according to, figure 1, while the gap 23 between the rollers in the marginal zones of the rolled material 24 is larger than in accordance with figure 1. If sets 25 and 26 would be displaced relative to each other in the opposite direction, then the middle zone of the gap 23 between the rolls would be larger compared to the gap in figure 1, while the gap 23 between the rolls in the marginal zone of the rolled material 24 would have a lower height than in figure 1.
Each work roll 17 and 19 over its entire length rests on the corresponding general support rolls 13 and 15, so that a uniform pressure is maintained between the rolls. As a result of a corresponding displacement of the kits with respect to each other, it is possible to establish certain forms of the gap 23 between the roll: m. The spreader 11 allows even more precise adjustment of the gap between the rolls to a certain shape.
When the rolls are positioned in accordance with FIG. 3, not only the work rolls 17 and .19 are mutually axially displaced relative to each other, but also each work roll 17 and 19 have an axial displacement relative to the corresponding support roller 13 or 15. As a result, it is possible to influence the pressure distribution between the barrels 27 and 29 in contact with each other, as well as 28 and 30

respectively, the upper 25 and lower 26 sets, thus ensuring further optimization of the shape of the gap 23 between the rollers, which is shown here with different heights along its width. This additional, as compared with FIG. 2, mixing work rolls 17 and 19 with respect to the support rolls 13 and 15 as a result of very precise adjustment of the gap between the rolls between the rolls, allows for even wider compensation of strip irregularities or even more comprehensive changes in the shape of the rolled material. 24. Due to the open installation of the ends of the drums 29 and 30 work rolls 17 and 19, the spacer arrangements of the work rolls 11 can, with little effort, impact the rolls favorably.
Figure 4 shows the rolls of a six-roller stand with the upper complex 31, with the upper supporting roller 32, with the upper intermediate roller 33 and with the upper working roller 34, as well as with the lower set 35, 1-sharpened roll 36, lower intermediate roll 37 and lower. work roll 38. Between work rolls 34 and 38, a gap 39 is visible in which the rolled material 40 is in the form of a tape. The rollers 32, 33, 34, 36, 37 and 38 are also profiled and have a curved, axisymmetric about the center contour of the barrel, with one half of the barrel rolls 32, 33, 34, 36, 37 and 38 having a curvature of the convex shape, while the other half of the barrels of the corresponding roll has a concave contour. Rolls 32, 33, 34, 36, 37 and 38 are depicted in their middle axial position. The gap 39 between the rollers across its width has the same height. Figure 5 also shows the rolls of the sixth stand in accordance with FIG. 4, however, with sets of 31 and 35 displaced relative to each other, similar to those in FIG. 2. The gap 39 between the rollers corresponds to the gap between the rollers in Fig. 2. Only the intermediate rollers 33 and 37 are displaced in opposite directions from the middle axial position (Fig. 6). However, there is the possibility of axial displacement of each pair of rolls 32 and 36, 37 and 33, 37 and 34, 38 independently of the other pairs of rolls, so

and roll spacers. As a result of the additional presence of an intermediate pair of rollers 33 and 37, it is possible to regulate the contour of the gap 39 between the rollers even more sensitively than, for example, using the kit (Fig. 3).
The roll system of a six-high stand (FIG. 7) consists of an upper set 41, comprising an upper support roll 42, an upper intermediate roll 43 and an upper work roll 44, as well as from the lower

Therefore, the system of rolls (Fig. I) is particularly advantageous because workers 54 and 58, which, compared with intermediate 53 and 57 and supporting 52 and 56 rollers, have a short service life, often have to be reground. But regrinding cylindrical rolls is simpler than regrinding rolls with a curved barrel contour.
