Definitions

  • the invention relates to multi-roll stands for rolling strip-shaped rolling stock, with a lower and an upper Work roll, the work rolls associated with backup rolls, Roll bending devices for the work rolls as well Means for adjusting and balancing the back-up rolls, wherein the lower and the upper work roll of the roll stand in two lower and two upper backup rolls are stored, the symmetrical to the vertical roll axis plane of the work rolls arranged and in pairs in lower and upper Support roll chocks are stored.
  • a multi-roll stand of this kind is from the JP 10 263 632 A is known.
  • DE 195 18 144 A1 describes a rolling mill with Work rolls, which due to the small roll diameter, the Problem of horizontal deflection during the rolling process in itself mountains.
  • this rolling mill is the upper and the lower Work roll each by a generated by the rolling force Peripheral force of the introduced into the support rollers rolling moments driven.
  • the work rolls means Supported roller pairs supported. The so at two lines of contact to the back-up rollers guided work rolls allow only one limited adjustment range of the work roll bend.
  • Multi-roll stands according to EP 0 665 067 B1 have Work rolls with the smallest diameter and sufficient Support, however, require a considerable amount Effort of measures to compensate for the deflection of the Roller sets such as support rollers and bending devices and are limited in terms of achievable tape thickness reduction.
  • the invention has for its object to provide a rolling stand for develop flexible rolls of strip material.
  • the rolling stand 1 according to FIGS. 1-3 for flexible rolling of Strip material 2 has a lower and an upper work roll 3, 4 on which, to avoid a horizontal deflection in two lower and two upper support rollers 5, 6, 7, 8 are mounted, the symmetrical to the vertical roll axis plane 9-9 of Work rolls 3,4 arranged and in storage units 10a, 10b, 11a, 11b slidable in the axial direction in the lower and upper Support roll chocks 10,11 are mounted, which in the two Roll stands 12, 13 of the roll stand 1 vertically and horizontally are guided displaceably.
  • the support rollers 5,6,7,8 are through to the Support roll chocks 10, 11 mounted motors 14 driven.
  • the lower and upper work rolls 3,4 are in lower and upper work roll chocks 15,16 stored in the two roller stands 12,13 guided vertically displaceable and be acted upon by work roll bending means 17,18.
  • the balancing of the support rollers 5,6,7,8 is done by on the lower and upper backup roll chocks 10, 11 acting balancers 19,20.
  • the force acting on the upper pair of support rollers 7,8 rolling force F allows due to the decomposition of forces in a horizontal rolling component F h and a radial rolling force F r when approaching a same coefficient of friction between the upper support roller 7,8 and upper work roll 4 by a factor of 1 / cos ⁇ improved introduction of the rolling moment M w in the upper work roll 4, wherein the rolling moment M w by the force acting in the circumferential direction of the support rollers 7.8 and the work roll 4 component F is determined and the rolling force F (Fig. 4).
  • a pressure medium Work roll bending devices 17, 18 operate between one bottom, the contact between the support rollers 5,6,7,8 and the Work rolls 3,4 ensuring and slip preventive Pressure, which at the same time a permanent balance of Work rolls 3,4 guaranteed, and one as positive Bending force acting maximum pressure.
  • the regulation of the work roll bending devices 17,18 takes place as a function of the rolling force F, of the bandwidth 22 and the displacement position of the support rollers 5,6,7,8.
  • the four support rollers 5,6,7,8 are to compensate for occurring Rollset deflection and to adapt to the Bandwidth 22 of the strip material 2 by the same or different distances S independently of each other vertical center plane 23-23 of the roll stand 1 in opposite directions axially displaceable.
