Definitions

  • the invention relates to a roll stand with a CVC roller pair, preferably a CVC work roll pair and a backup roll pair having a contact area in which acts a horizontally acting moment that leads to a Entanglement of the rollers and thereby to axial forces in the roller bearings leads.
  • EP 0 049 798 B1 describes a rolling mill with work rolls, optionally supported on back-up rolls or back-up rolls and intermediate rolls, wherein the work rolls and / or backup rolls and / or intermediate rolls against each other axially displaceable and each roller at least one of these Roller pairs with a curved towards running towards a bale end Contour is provided, which is followed by the two rollers respectively extends opposite sides over part of the Walzgutbreite.
  • the rolled strip cross section is almost exclusively due to the axial displacement the rollers provided with the curved contour, so that the use of a roll bending is unnecessary.
  • the curved contour of both Rolls runs over their entire bale length and has a shape that is complemented in a certain axial position of both rolls complementary.
  • roller peripheral forces causes a moment around the center of the scaffolding, which is used to secure the rollers and thus to axial forces can lead in the roller bearings.
  • the invention is based on the object, in a generic rolling mill Provide measures that minimize the axial forces of the roller bearings become.
  • the task is characterized by the characterizing features of Claim 1 solved. Simply by changing the shape of the CVC rollers The moments acting in a horizontal direction can be done without additional effort be minimized.
  • the polynomial coefficient a 0 results from the current roll radius.
  • the polynomial coefficients a 2 , a 3 and a 4 a 5 , etc. are set so as to give the desired setting range for the CVC system.
  • the polynomial coefficient a 1 is independent of the adjustment range and line load between the rollers and thus freely selectable. This wedge factor or linear component a 1 can be selected so that minimal axial forces occur when using CVC rollers.
  • the optimum wedge factor a 1 is determined offline and as an average value from various shift positions of the CVC rollers (eg minimum, neutral and maximum shift position). Although a complete compensation of the axial forces of the roller bearings is not achieved by averaging, but a minimum value of the same over the entire adjustment range of the rollers.
  • these tangents run but also parallel to the roll axis.
  • CVC work rolls 1 are in different Displacement positions shown.
  • the work rolls 1 are of support rollers. 2 supported. Between the work rolls 1 is a rolled strip. 3
  • the load in the nip is assumed to be constant over the rolled strip 3 and independent of the shift position of the work rolls 1. It is represented by arrows 4.
  • the load between the CVC work rolls 1 and the backup rolls 2 is distributed unequally over their contact area b cont and changes with the shift position of the work rolls 1. This load is represented by arrows 5.
  • the sum of the loads represented by the arrows 4 and 5 is equal and opposite.
  • FIG. 3 shows a conventionally ground CVC work roll pair, which was designed with the goal of smallest diameter differences.
  • the an end diameter 7 and the convex portion of the roller contacting tangent 8 and the other end diameter 9 and the concave portion of the Roller touching other tangents 10 are parallel to the axes of the conventionally ground work rolls.
  • the corresponding run Tangents of the CVC rollers according to Figure 4 with optimized Wedge were designed in parallel, but with respect to the roll axes around the optimum wedge angle • (alpha) inclined.
