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 required final rolling temperatures can hardly be maintained, especially in the case of thin hot strips, especially with higher coil weights, which complicates the fact that due to the high number of individual passes on the finishing stand required for a corresponding quality of the rolling stock, there is a further considerable temperature loss is to be expected.
  • the strips to be rolled can only be descaled with one or very few passes in order to avoid higher temperature losses. Impairment of the quality of the belt surface can therefore hardly be ruled out. Because of the unavoidable temperature losses, there is finally a lower limit of the strip thickness that can be achieved, because with strip thicknesses of about 2 mm the permissible strip end temperature is already reached.
  • 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 guaranteed for medium and high coil weights can.
  • the invention solves the problem in that the roughing stand and the finishing stand are arranged immediately 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 a rapid reduction in the thickness of the rolling stock, so that the rolling stock is still too thin at 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 finishing stand and the last stitch or the last pass can be carried out with the finishing stand alone.
  • the usual heads 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 increases 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 at corresponding locations.
  • the system shown differs from conventional hot rolling systems of a comparable type in that the roughing stand 3 and the finishing stand 4 lie directly one behind the other and can be switched from an optional individual operation to a tandem operation.
  • a very rapid reduction in the thickness of the rolling stock can consequently be achieved by the simultaneous use of both stands 3 and 4.
  • 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, whereby the work rolls have a comparatively long service life due to the possible division into individual stitches. It does not need to be explained in more detail that the arbitrary use of one of the two scaffolds or both scaffolds can meet a wide variety of requirements.
