Definitions

  • the invention relates to a roll stand with two work rolls, two intermediate rolls and two support rolls, i.e. a so-called six-high roll stand, in which at least the support rolls and the intermediate rolls lie essentially one above the other in the same vertical plane, in which the intermediate rolls between the support rolls and the work rolls are also axially displaceable are arranged and in which stand-fixed blocks are provided on the one hand with vertical guide surfaces for the chocks of the work rolls and the intermediate rolls and on the other hand have adjusting means for balancing and bending the rolls, certain adjusting means with direction of action against the upper support roller being able to bring the chocks of the upper intermediate roll into effect are.
  • cylindrical work rolls can also be used if they are assigned, for example in accordance with DE-AS 12 81 981, roll bending devices which act on the chocks of the work rolls and are so effective that they touch the ends of the Spread the work rolls opposite the roll gap in the opposite direction to the deflection that normally occurs.
  • a generic six-high roll stand is part of the prior art through BR patent application 678285.
  • the work rolls and the intermediate rolls with their chocks are each guided between stationary blocks, which on the one hand have adjustment means for balancing and bending the rolls, but on the other hand are also provided with vertical guide surfaces for the chocks of the work rolls and the intermediate rolls.
  • cylindrical ground work rolls are also used, the adjusting means assigned to their chocks in the blocks being designed as roll bending devices which counteract the deflection of the free end sections of the work rolls projecting beyond the rolling stock.
  • adjustment means for the upper intermediate roll are also assigned in the blocks, which act on their chocks, on the one hand to bring about a balance thereof and on the other hand to be able to lift this intermediate roll from the work rolls when they are replaced have to.
  • DE-OS 27 52 750 also includes a six-high roll stand, which works with axially immovable work rolls, intermediate rolls and backup rolls, and in which the longitudinal extent of the effective bale surface of each backup roll is less than that of the intermediate rolls and in which the effective bale surface of the intermediate rolls is in turn less than that of each work roll.
  • At least the chocks of the intermediate rolls are assigned to roll bending devices.
  • roll bending devices By acting on these roll bending devices, it is to be achieved that the bale surfaces of the upper and lower work rolls in contact with the rolling stock run essentially in a straight line.
  • the six-high mill stand according to DE-OS 27 52 750 is only suitable for strip widths that move within relatively narrow limits because of the effective bale top area of the work rolls in relation to the intermediate rolls on the one hand and the intermediate rolls in relation to the backup rolls on the other hand and thus the deflection of the work rolls can only be effectively influenced over those end regions which are not supported by the bale surface of the intermediate rolls and the backup rolls.
  • the minimum width of the rollable strip material is therefore dependent on the effective bale length of the back-up rolls, while its maximum width is determined by the effective bale length of the intermediate rolls.
  • the invention has for its object to provide a six-high roll stand of the generic type, that is, a six-high roll stand with axially displaceable intermediate rolls, which is suitable for rolling out strips of a wide range, which for all rollable strip widths with constant operating conditions and as small as possible Hertzian pressure between the work rolls and the intermediate rolls works as well as an optimal choice of diameter for the work and intermediate rolls - based on the rolling task and the control of the peripheral forces - and finally also allows the problem-free changing of the work and intermediate rolls.
  • the chocks provided in the blocks are assigned adjusting means as bending devices, that on each block a lower and an upper guide piece provided with the guide surfaces for the chocks of the intermediate rolls can be moved vertically is guided, and that the adjusting means forming the bending devices for the intermediate rolls are provided such that they can be displaced relative to the guide pieces and / or the chock in the horizontal direction parallel to the roll axes.
  • This structure of a six-high mill stand according to the invention has the essential advantage that there is little wear on the work rolls because the work rolls are not to be corrected around the edge of the intermediate rolls.
  • the shifting conditions for the intermediate rolls are also significantly improved. It has also been shown that due to the achievable favorable Hertzian pressure and the high temperature gradients (large material tensions) on the work rolls, a higher security against shell breakouts can be achieved.
  • the measures according to the invention also prevent a mutual impairment of the available design spaces, so that with an optimal choice of diameter of work rolls and intermediate rolls there is no restriction with regard to the design of the effective force transmission systems for the bending correction forces, so there are no dimensioning difficulties.
  • each guide piece consists of a stator-side part and a part assigned to the chock of the intermediate roller, the adjusting means forming the bending device being arranged between these two parts.
  • an advantageous type of roll stand is characterized in that the two parts of the guide pieces can only be displaced vertically relative to one another, that between them two adjusting means, which are located one behind the other in the axial direction of the intermediate rolls, act as bending devices and that the chocks of the intermediate rolls are relative are arranged exclusively horizontally displaceable to the parts of the guide pieces assigned to them.
  • the adjusting means forming the bending device are installed in the stator-side part of the guide pieces and act on the chock-side part thereof.
  • Another advantageous training possibility for a rolling stand according to the invention is that the two parts of the guide pieces are horizontally and vertically displaceable relative to one another, that between them an adjusting means built into the chock-side part of the guide pieces is provided in each case on the central plane of the intermediate roll chocks , and that the chock-side part of the guide pieces is connected to the associated chock horizontally displaceable relative to the stator-side part.
  • the adjusting means serving as a bending device consist of hydraulically actuatable piston-cylinder units which are installed in one part of the guide piece, while the piston rod acts on the other part.
  • piston-cylinder units are double-acting and are anchored to both parts of the guide pieces in a tensile and compressive manner.
  • the structure according to the invention is not only suitable for six-high roll stands in which all the rolls - work rolls, intermediate and back-up rolls - lie on a common vertical plane, it can also be used in six-high roll stands of the type in which the work rolls are made of vertical axis plane of the intermediate rollers and the support rollers are displaced and are supported in the direction of displacement by intermediate rollers and / or support rollers mounted on support bridges on their bales, as is known per se from DE-AS 25 22 213.
  • a roll stand An important feature of a roll stand according to the invention is that the guide pieces which are guided vertically displaceably in the blocks and which contain the adjusting means forming the bending devices are positively connected to the chocks of the intermediate rolls by horizontal guides in the vertical direction, which are parallel to the roll change between the stands the rollers are continued.
  • the smallest diameter of the intermediate rolls is only limited by the height of their chocks or the guide pieces provided between them and the stand.
  • the roll stand according to the invention can be developed with simple means so that there is an effective expansion of the bending correction range, which enables an improvement in the strip profile quality and also an optimization of the joint pressures on the one hand at the contact points of the work rolls with the intermediate rolls and on the other hand at the contact points of the intermediate rolls with the support rollers.
  • This can be achieved by the fact that also the chocks of both work rolls lök- in the B ken provided adjusting means are assigned as bending devices which engage at guide pieces, which are in turn supported on the one hand on vertical guides in the blocks and have on the other hand horizontal guides for the chocks of the invention .
  • the particular advantage of such a measure is that by simultaneously engaging the bending device separately assigned to the intermediate rolls and the work rolls the strip profile quality can be increased so that the separate controllability of the joint pressures at the contact points of work rolls and intermediate rolls, as well as intermediate rolls and back-up rolls, enables roll wear to be reduced and the roll load and the roll bearing load to be reduced.
  • the backing roll profile correction can be brought about by the bending of the intermediate rolls, while on the other hand the bending of the work rolls can be used for process interventions.
  • each guide piece consists of a stand-side part and a part assigned to the chock of the work roll, the adjusting means forming the bending device between them both parts are arranged and the stator-side parts of the guide pieces of both work rolls are connected to one another via piston-cylinder units.
  • Another important embodiment is also seen according to the invention in that the two parts of the guide pieces can only be displaced vertically relative to one another and the chocks of the work rolls are in turn only provided horizontally displaceable relative to the parts of the guide pieces assigned to them.
  • the adjusting means forming the bending device can - like the piston-cylinder units - be installed in the part of the guide pieces on the stator side and act on the part of the same on the mounting piece side.
  • the adjusting means forming the bending device in the chock part of the guide pieces on the side and engage the part on the stator side.
  • the adjusting means consist of hydraulically actuated piston-cylinder units and are designed to be double-acting and engage between the guide pieces in a manner that is resistant to tension and compression.
  • the guide pieces containing the bending devices of the work rolls which practically hardly exceed the work roll chocks and thus favors the optimal choice of diameter for the work and intermediate rolls.
  • the roll stand shown in FIG. 1 has in the usual way two roll stands 1 arranged next to one another at a distance. only one of which is shown in FIG. 1.
  • two work rolls 2 and 3 two intermediate rolls 4 and 5 and two support rolls 6 and 7 are accommodated, so that a so-called six-high roll stand is formed.

  • the chocks 13 of the upper work roll 2 are positively connected in the vertical direction, but are horizontally displaceably connected to guide pieces 17 for the changing process, which in turn are guided vertically displaceably in the blocks 12 fixed to the stand.
  • the chocks 14 of the lower work roll are connected to guide pieces 18, which are also guided vertically displaceably in the blocks 12 fixed to the stand.
  • the chocks 15 of the upper intermediate roll 4 F 19 are assigned üh- approximately pieces, but where here too the chocks 15 are in the vertical direction form-fitting horizontally slidable with the guide pieces 19 in engagement.

  • the horizontal guides 21 between the chocks 15 and 16 for the intermediate rolls 4 and 5 and the associated guide pieces 19 and 20 are designed so that they not only allow the change of the intermediate rolls 4 and 5 together with the work rolls 2 and 3, but that they also ensure an axial displacement of the intermediate rolls 4 and 5 relative to the work rolls 2 and 3 and to the support rolls 6 and 7 for the rolling operation.
  • the axial displacement of the intermediate rolls 4 and 5 is important for the rolling operation because this allows the rolling stand to be adjusted to the different widths of the strips to be rolled out. This setting prevents the rolling out of the rolled strips in the region of their longitudinal edges and the particularly high stress on the sections of the work rolls which act on the rolled material edges.
  • the mounting pieces 15 of the upper intermediate roll 4 and the corresponding mounting pieces 16 of the lower intermediate roll 5 are each adjusting means 22 in the form of the blocks 12 fixed to the stand in the form of hydraulically actuatable piston-cylinder Associated units, their arrangement and training clearly 2 and 3 results.

H. the left-hand guide pieces 19 and 20 are each mirror images of the right-hand guide pieces 19 and 20, while the upper guide pieces 19 in turn assume a mirror-image position to the lower guide pieces 20 in the roll stands 1.

  • the adjustment means 22 forming the bending device for the intermediate roller 4 or 5 are installed, which in turn engage via their piston rod 25 on the chock-side part 24.
  • the operative connection between the piston rods 25 of the adjusting means 22 and the chock-side part 24 of each guide piece 19 or 20 is of such a type that with the help of the chocks 15 or 16 bending forces on the intermediate roller 4 or 5 at least in the direction against the Back-up roller 6 and 7 can be exercised.

  • This is on the one hand, it is necessary to make the adjusting means 22 double-acting and, on the other hand, to connect their piston rods 25 with tensile and pressure resistance to the chock-side part 24 of the guide piece 19 or 20.

  • the two adjusting means 22 installed in each guide piece 19 and serving as a bending device for the intermediate roller 4 or 5 have the purpose of keeping the bending lever arm of the intermediate roller 4 or 5 constant in any possible axial displacement position thereof. Therefore, the two adjusting means 22 are designed such that they each depend on the momentary axial sliding position of the two intermediate roller chocks 15 and 16 relative to the guide piece 19 with regard to the actuating forces exerted by them. can be varied. In the axial sliding position of the intermediate roller chock 15 shown in FIG. 3, the higher adjusting force is applied by the adjusting means 22 'and the lower adjusting force by the adjusting means 22 ". The reverse is true if the intermediate roller chock 15 has the opposite axial extreme position Varying the actuating forces also ensures that all four individual forces acting on an intermediate roller act symmetrically with respect to their transfer to the backup roller to the center of the stand.
  • the force arrows 26, 27, 28 and 29 indicate the position and effect of the four adjusting means 22 acting as an intermediate roller bending device

  • the relative position of the double arrows 30 and 31 on the one hand to the force arrows 26 and 27 or 28 and 29 and on the other hand to the arrows 32 and 33 corresponds to the respective axial displacement position of the intermediate roller chocks and thus also the intermediate roller relative to the associated work roller and the associated backup roller.
  • the basic structure of the six-high rolling mill shown in FIG. 5 corresponds completely to that of the rolling mill according to FIG. 1. However, the structure and mode of operation of the guide pieces 19 and 20 for the two intermediate rolls 4 and 5 are different here.
  • Ig from F. 6 is shown based on the upper right guide piece 1 9 that the guide pieces 19 and 20 in turn have a stator-side part 34 and a chock-side part 35, but that an intermediate part 36 is also present.
  • the stand-side part 34 is installed as a component of the block 12 in the roll stand 1.
