Definitions

  • the invention relates to a method and a system for hot rolling of strips, the rolling stock being rolled in at least one reversing roughing stand in a number of preliminary passes to a preliminary strip and transported via an intermediate roller table into at least one Steckel finishing stand and therein in a number from stitches to finished strip of predetermined thickness and finally wound into a bundle.
  • the length of the roller table is customary to choose the length of the roller table between the roughing stand and Steckel finishing stand in such a way that the opening is "free” between the roughing stand and the cropping shear after it has left the roughing stand.
  • the length of the roller table is therefore essentially determined by the length of the supporting strip.
  • the invention has for its object to provide a method and a system for hot rolling of strips of the type corresponding in the preamble of claim 1 or claim 6, which avoid the disadvantages mentioned and can be carried out using uncomplicated measures and means.
  • the length of the intermediate roller table which is determined by the length of the preliminary strip, is shortened and that at least during the last preliminary stitching of the preliminary strip, a tandem rolling of roughing stand and finishing stand is carried out.
  • the possibility of shortening the roller table according to the invention results from the fact that the requirement for a "free" run-out of the preliminary strip dropped after one of the last preliminary stitches or after the last preliminary stitch and instead a tandem rolling of preliminary and finishing stands with synchronization the rolling speeds is made.
  • a system for hot rolling strips comprising at least one reversing roughing stand for roughing a roughing strip and at least one Steckel finishing stand for reducing the roughing strip to the finished strip, these being connected to one another by a roller table, the length of which is determined by the length of the roughing strip, in particular for carrying out the method according to the invention is characterized in that the length of the roller table corresponds at most to the length of the preliminary strip before one of the last preliminary stitches.
  • the length of the roller table can correspond approximately to the distance between the scaffolding and the scissors.
  • the plant shown in Figure 1 for hot rolling of strips In a configuration according to the prior art, at least one reversing roughing stand (1) for roughing a roughing strip (10) and at least one Steckel finishing stand (3) for reducing the roughing strip (10) to the finished strip comprises. Both parts of the system, roughing stand (1) and finishing stand (3), are connected to each other by an intermediate roller table (2). As shown in Fig. 1, in the conventional system, the length of the intermediate roller table (2) is chosen so that the sliver (10) after it leaves the roughing stand (1) - it can be the last roughing stand of a series of roughing stands act - "free" between the roughing stand (1) and the cropping shear (4).
  • the length of the intermediate roller table (2) is essentially determined by the length of the sliver.
  • the finishing stand (3) comprises, as is known per se, reel furnaces (5 and 6).
  • FIG. 2 An embodiment of the system according to the invention is shown in FIG. 2.
  • the length (A 2 ) of the intermediate roller table (2) is at most equal to the length (L 2 ) of the support strip (10) before the pre-stitch n-2, where n is the number the stitches are in the roughing stand.
  • the distance between roughing stand (1) and finishing stand (3) is about 120 m in this conventionally designed plant, the number of stitches in the roughing stand (1) being "n".
  • the preliminary strip (10) just runs freely onto the intermediate roller table (2) between the roughing stand (1) and cropping shear (4) (Fig. 1).
  • a tandem rolling of roughing stand (1) and finishing stand (3) takes place because the roughing strip (10) also the length dimension (L 2 ) is longer than the distance (A 2 ) between the roughing stand (1) and the finishing stand (3).
  • the required length of the intermediate roller table (2) can therefore be reduced by 94.74 m - 53.29 m by 41.45 m.
  • Tandem rollers synchronize the rolling speeds of the roughing (1) and finishing stand (3).
  • tandem rolling process synchronizes the transport speed and the transport direction of the intermediate roller table with the rolling speed and rolling direction of the preliminary (1) and finishing stand (3).
