Definitions

  • the invention is based on a method for rolling finished profiles from a Pre-profile by means of a roll stand arrangement working in reversing mode, the one compact rolling group, consisting of an input-side first universal stand, an output-side second universal scaffold and one, between forms this universal scaffolding arranged intermediate intermediate frame, the Compact rolling group, offset, parallel to its rolling line one, two or more rolling stands existing pre-rolling group with free rolling material outlet and one, arranged between the two rolling lines transverse displacement device.
  • the large number of shape calibers required for roughing requires this Rolling mills with large reversing stands and because of the large number of shape calibers large bale lengths of the rollers as well as complex equipment for the introduction of the rolled stock in the different calibers.
  • the large rolling lengths are essential long rolling times and therefore do not allow the rolling time in the continuous road on the working time cycle e.g. one that provides the initial profile Coordinate continuous casting plant, which is why for such a combined operation Large interim storage facilities must always be available. For those with roughing subsequent fully continuous rolling are then at least six to eight roll stands and the associated drives required. Furthermore different temperatures can be achieved in the continuous rolling processes do not avoid over the length of the roll.
  • the invention has for its object a roll stand arrangement of the above to design and operate the generic construction described, that the same advantages are achieved when rolling rails as before achieved with such roll stand arrangements when rolling other finished profiles were.
  • Pre-profile and use of a vertical roll stand instead of the above Universal stand in the roughing group can also compress the roughing profile on both ends and the compression intermediate stand of the compact rolling group can have three optional calibres, the preliminary profile then being dimensioned such that its flange lugs 1.2 to 4 times the head width and the other flange correspond to 1.2 to 3 times the base width of the finished rail profile.
  • the pre-profile in the roughing group can be reversed in three passes consecutively be preformed.
  • VVG duo vertical scaffold
  • FIG. 2 corresponds to that of FIG. 1 with the Provided that in the roughing group instead of the roughing mill stand VUG a duo vertical scaffold VVG is provided.
  • Vignol rail made from a continuous casting pre-profile VP with Rectangular cross-section. This profile is in a first stitch U1 in the VUG universal stand of the roughing group using the profiled Horizontal rolls HW a by a distance d to the vertical Longitudinal center x-x of the preliminary profile VP offset chamber bay KB formed, wherein the vertical rollers VW the intended width of the cross section to back up.
  • the choice caliber WH1 see Fig.
  • a pre-profile VP reinforced at both ends a so-called dog-bone, which also comes from a Stranggußeinrichutng used.
  • the Sequences in the roughing stand group correspond to those according to FIG. 3 with the proviso that the pre-profile VP after leaving the universal scaffold VUG again after the third stitch U3 through the first choice caliber WH1 of the intermediate compression mill VHG and then in the reversing direction with one stitch U4 and one Reversing stitch U5 through the universal scaffold, from this in one single stitch H3 through the second choice caliber (Fig. 4a) of the horizontal duo stand VHG and then via the cross conveyor QE into the compact rolling group with a sequence accordingly 3 using the two optional calibers WE1 and WE2 of the intermediate upsetting stand SZG according to FIG. 4b.
  • the preliminary profile is then on the cross conveyor QG fed to the compact rolling group and in the first five stitches U1, E1, U2, U3, E2 in the, in FIGS. 3 and 4 treated way. Then follow in reversing Direction a stitch U4 and a reversing stitch U5 in the input side Universal scaffold EUG, to which a stitch in the E3, in this Case of third choice caliber WE3 of the compression intermediate stand SZG and on this, as in the previous cases the final stitch with the profiled horizontal rollers HW of the universal stand on the output side Connect AUG.
  • the stitch distribution shown here between roughing group and Finishing roll group provides a very balanced distribution of the forming work on both roll groups, with more passes in the finish roll group be rolled; this is different from the previous one Example shown, three instead of two optional calibers in the finishing mill group necessary.
  • the rolling pass map shown in Fig. 6 becomes a continuously cast pre-profile VP with one to be rolled Used rail-like plug-like cross-section, which, as indicated by dash-dotted lines, lying directly on the horizontal duo frame VHG fed to the roughing group and in this with successive reversing stitches R1, RH1 and H1 reduced so far is that it is the input-side via the transverse transport device QE EUG universal stand supplied to the compact rolling group can be.
  • a pre-profile with lighter be used to cast trapezoidal cross-section is different in the roughing group than in the 6 the vertical duo stand VVG acc. Fig. 2 fed and in the subsequent stitches according to those after Fig. 6 shaped and finish rolled.
