Definitions

  • the invention relates to a method for operating a roll stand system, which consists of one or more rough stands, which is followed by a compact rolling group offset transversely to the rough stands via connecting roller tables and a transverse transport device, which consists of a first and a second universal stand or duo stand and one between them arranged intermediate intermediate stand, wherein the roll stand system, pre-profiles coming from a continuous casting device are fed directly or after intermediate storage.
  • these roll stand systems are operated in such a way that the rolling stock in the compact rolling group, which is subjected to rolling by the roughing stands, is roll-formed in an odd number of passes. It has also already been proposed to achieve an even number of passes through the compact rolling group in that, if these roughing stands are arranged appropriately for the continuous casting device, the roughing profile is introduced into these roughing stands counter to the rolling direction and the rolled end of the rolling stock was then introduced into the compact rolling group.
  • the invention has set itself the task of increasing the performance of the compact rolling group by creating the possibility, depending on the number of deformation stitches actually required in the compact rolling group, the number and sequence of passes of the rolling stock strand optimally to be determined.
  • the rolled material strand acted upon by the roughing stands is optionally supplied to the compact rolling group from one or the other inlet side depending on the number of passes specified by the respective rolling program.
  • the roll stand system can be designed such that a further second transverse transport device is arranged behind the second universal stand or duo stand, which is connected to the latter via an extension of the connecting roller table leading from the roughing stands to the first transverse transport device.
  • the preliminary profile, not shown, coming from the continuous casting device, also not shown, is introduced in the direction of arrow E with a preliminary stitch V1 into the preliminary stand SVG, in the place of which several preliminary stands can also be introduced a subsequent reversing stitch R1 and a further roughing stitch V2 and then further applied in the direction of the original arrow E to the transverse transport device QT and from there, laterally shifted, further in the direction of arrow E into that of the universal stand UG1, the intermediate intermediate stand STZG and the universal stand UG2 existing compact rolling group was introduced, in which a rolling process with exit in the direction of the arrow A3 indicated in broken lines is possible with a stitch 1, the following reversing stitch and the subsequent stitch 3, that is to say after a total of three passes.
  • the strand of rolled material is to be further roll-formed, this can be done after a further reversing stitch and the subsequent stitch 5 in the direction of arrow A5 or after a further reversing stitch and the stitch 7 in the direction of arrow A7.
  • the shaping of the rolling stock entering the roughing stand group SVG in the direction of arrow E is carried out in the same way as in the embodiment according to FIG. 1.
  • the preformed rolling stock is then, unlike in the case of the 1 on the roller table R at a distance parallel to the compact roller group UG1, STZG, UG2 fed to the transverse transport device QT and, moved on this, against the direction of arrow E in the direction RE in the compact roller group and then either with a stitch and a subsequent reversing stitch, ie a total of two stitches, or a further stitch and a subsequent reversing stitch, ie four passes or a further following pass and reversing pass, i.e. a total of six passes, finish-rolled.
  • the odd-numbered sequences 3, 5, 7 were thus possible for the finish rolling and in the embodiment according to FIG. 2, the even-numbered sequences 2, 4, 6.
  • transverse transport device QT1 interposed is a roller table that connects to the input of this transverse transport device and leads parallel to the compact rolling group UG1 STZG and UG2 attached to this second transverse transport device QT2.
  • the pre-rolled rolled stock in the one case is fed to the compact rolling group UG1, STZG, UG2 via the transverse transport device QT1 or via the transverse transport device QT2, as can be seen from the two sequence plans assigned to these transverse transport devices QT1 and QT2.
