Definitions

  • the invention relates to a system for hot rolling strip or sheet-shaped rolling stock with a reversible roughing stand and a reversible finishing stand.
  • the invention is therefore based on the object to avoid these deficiencies and to improve a system for hot rolling strip or sheet-shaped rolling stock of the type described in such a way that an economical production of thin hot strip with a good surface quality can also be ensured for medium and high coil weights can.
  • the invention solves this problem in that the roughing stand and the finishing stand are arranged directly one behind the other and can be converted from optional individual operation to tandem operation.
  • the direct succession of the two rolling stands makes it possible in an advantageous manner to drive the roughing stand and the finishing stand in a tandem operation, which, with good use of the capacity of the roughing stand, allows the thickness of the rolling stock to be reduced rapidly, so that the rolling stock becomes too thin at still permissible final temperatures can be rolled out.
  • the surface quality of the rolling stock is not affected by the roughing stand, because the finishing stand is arranged after the roughing stand and the last stitch or the last pass can be carried out with the finishing stand alone. The usual preliminary stitches are of course carried out on the roughing stand.
  • the achievable rapid reduction in thickness of the rolled stock not only ensures a sufficient final temperature for hot strips with a thickness of less than 2 mm, but also an increase in capacity compared to hot rolling mills with separate roughing and finishing stands.
  • the rolling stock is brought to the desired rolling temperature in an oven 1.
  • the heated rolling stock is then descaled in a scale washer 2, before it is fed to the roughing stand 3 and the finishing stand 4 directly adjoining the roughing stand 3.
  • furnaces 5 are arranged upstream and downstream of these two stands 3 and 4 in order to avoid excessive temperature losses.
  • the hot rolled strip is wound on a reel 6, which is preceded by a pair of scissors 7.
  • Drivers 9 are provided on appropriate stands for driving the rolling stock on a roller table 8.
  • the system shown differs from conventional hot rolling mills of a comparable type in that the roughing stand 3 and the finishing stand 4 lie directly one behind the other and can be converted from an optional individual operation to a tandem operation.
  • the simultaneous use of both stands 3 and 4 can result in a very rapid reduction in the thickness of the rolling stock. This significantly improves the temperature balance, which leads to better descaling and an increase in surface quality.
  • the rolling capacity is increased and the length of the rolling mill is reduced by about 1/3, which is associated with a considerable reduction in investment costs.
  • the surface quality is further improved by separating pre-stitches and finished stitches, with the work rolls having a comparatively long service life due to the possible division into individual stitches. The fact that the most varied requirements can be taken into account by the arbitrary use of one of the two scaffolds or both scaffolds need not be explained in more detail.
