Definitions

  • the invention relates to a four- or six-roll stand with laterally supported work rolls, each support having a radially non-supported, intermediate work roll lying on the associated work roll and two radially mounted support rollers.
  • the work rolls, the support rolls and, if appropriate, the intermediate rolls are either arranged in a common vertical plane, in which case supports are provided on both sides of the work rolls, or the work rolls and, if appropriate, the intermediate rolls are opposite the vertical one determined by the axes of the support rolls Level laterally offset, then one-sided support of the work rolls and possibly the intermediate rolls is sufficient.
  • the reason for using the supports is to avoid uncontrolled horizontal bending of the work rolls.
  • the lateral support is at Work rolls necessary, the ratio between the diameter of the work roll and its useful length exceeds 1: 4.
  • the supports can also be bent horizontally in a controlled manner in order to influence the strip cross section to be rolled.
  • the supports generally consist of a relatively thick side intermediate roller, which is in contact with the associated work roll, and two radially mounted support rollers, on which the radially non-supported side intermediate roller is supported (GB-PS 1 488 796; GB-PS 1 329 971) .
  • the support rollers can each consist of a continuous roller or of shorter rollers arranged in a row.
  • the reason for the formation of the support in the form of a relatively thick lateral intermediate roller and two supporting rollers supporting it is that the space in which this support is to be accommodated is particularly narrow when the diameter ratio between the work roller and the perpendicularly adjacent intermediate - or backup roller is small, for example only 1: 3.
  • a wedge-shaped space is created, which is limited on the one hand by the strip to be rolled and on the other hand by the jackets of the work roll and intermediate roll or backup roll.
  • the required lateral support forces can only be applied when using relatively thick lateral intermediate rollers, because only then is there enough space available to accommodate correspondingly large support rollers that can absorb the required support forces.
  • Lateral supports with relatively thick lateral intermediate rolls with a correspondingly large mass moment of inertia have an unfavorable effect, however, since the transmission of the rotary movement originates from the work roll and therefore a slip between the rolls can occur in the acceleration phase. This allows Surface damage occurs, which is transferred to the rolling stock.
  • the wedge-shaped space for accommodating the lateral support can be too small because of the support rollers which are to be dimensioned relatively large.
  • the invention has for its object to improve the lateral supports of the work rolls in a multi-roll stand in such a way that the support capacity of the support is improved and the risk of slippage between the rotating parts of the lateral intermediate roll is reduced.
  • the support has a further lateral intermediate roller and that one side intermediate roller is supported on one of the two support rollers and the further side intermediate roller, which is supported on the other support roller and in a four-roll stand is supported on the support roller and in the case of a six-roll stand on the intermediate roller.
  • the further lateral intermediate roller and its special support Due to the use of the further lateral intermediate roller and its special support, it is achieved that with a relatively small diameter of the intermediate rollers there is sufficient space for accommodating correspondingly large supporting rollers, the supporting rollers being driven specifically by the respective intermediate roller. This improves the functionality and support capacity of the support.
  • the risk of slippage between the work roll and the side intermediate roll lying directly against it is reduced because, on the one hand, the intermediate roll has less Has moment of inertia and on the other hand, an additional torque is transmitted to the intermediate roller via the further intermediate roller from the support roller or intermediate roller of the roll stand.
  • a roll stand 1 of a six-roll stand two backup rolls 2, two intermediate rolls 3 and two work rolls 4 are mounted.
  • a lateral support is assigned to each work roll 4 on each side.
  • Each support has two support rollers 6, 8, which can each consist of a continuous roller or of roller sections.
  • the two support rollers 6, 8 are mounted radially in a support roller suspension 9.
  • the support roller suspension 9 can be adjusted in the direction of the work roll 4 by means of an adjustable support element 10.
  • Each support also has two lateral intermediate rolls 5, 7, which are considerably smaller in diameter than the work roll 4 and the support rolls 6, 8. These intermediate rollers 5, 7 are not supported radially.
  • the first lateral intermediate roll 5 supports the work roll 4 laterally. For its part, it is supported on the first support roller 6 and on the second lateral intermediate roller 7.
  • the second lateral intermediate roller 7 is in turn on the second support roller 8 and on the adjacent intermediate roller 3 of the Supported roll stand.
