Definitions

  • the invention relates to a system for hot rolling strip or sheet-shaped rolling stock with two reversing stands arranged directly behind one another between a front and a rear reversing reel.
  • the invention is based on the prior art according to FR-A-1 132 772.
  • a roughing stand and a finishing stand are used separately.
  • the roller roughness and the roller diameter can thus be adapted to the particular requirements of the shaping process.
  • the disadvantage must be accepted that the capacity of the roughing stand is poorly utilized and that on the one hand a large temperature loss is unavoidable due to the conveyance of the rolling stock from the roughing stand to the finishing stand and on the other hand because of the high number of individual passes required in the finishing stand, even if before and Holding furnaces are provided behind the finishing stand.
  • the consequence of this is that, particularly in the case of thin hot strips, the required final rolling temperatures can hardly be maintained, especially with higher coil weights.
  • the strips to be rolled can only be descaled in one or very few passes in order to avoid higher temperature losses. Impairment of the quality of the belt surface can therefore hardly be prevented.
  • a limitation of the strip thickness which can be achieved must be accepted downwards, because, due to the high temperature losses, the strip temperature which is still permissible is already reached with strip thicknesses of up to approximately 2 mm. It does not need to be explained in more detail that there is also a limited capacity of up to a maximum of 450,000 t / year.
  • 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 is guaranteed even for medium and high coil weights and the capacity can be increased significantly.
  • the invention solves this problem in that a roughing stand is provided directly in front of the front reversing reel and in that the stands can be converted from an optional individual operation to a joint operation, the rolling gaps of the reversing stands being able to be opened for free passage of the rolling stock during individual operation of the roughing stand.
  • a roughing stand makes it possible to adapt the work rolls advantageously in terms of their diameter and surface roughness to the respective deformation requirements.
  • the roughing stand is provided directly in front of the front reversing reel, the roller table between the roughing stand and the finishing stands, which receives the tape for the preliminary stitches, is omitted.
  • this measure helps to avoid the loss of temperature of the hot strip during the conveyance from the roughing stand to the finishing stands, and on the other hand it allows all the stands to be used together.
  • the connection of the roughing stand to the finishing stands means that when the roughing stand is operated individually, the hot strip must run through the open roll gaps of the 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 passed to the rolling stands, a roughing stand 3 and two reversing stands 4 serving as finishing stands is forwarded.
  • Two reversing reels 5 and 6 are arranged upstream and downstream of these reversing stands 4, and in order to avoid higher temperature losses, the reversing reels 5 and 6 can either be equipped with a heatable mandrel or with a heating hood.
  • the rolled hot strip is then wound on a reel 7.
  • a cropping shear 8 is provided between the rear reversing stand 4 and the rear reversing reel 6 for trimming the beginning and ends of the tape.
  • the selected arrangement of the cropping shears 8 offers the considerable advantage that both the beginning and the end of the band can be additionally trimmed after the finished stitches.
  • the rolling stock is transported in the usual way on roller tables 9, the driven reels 10 of a driver 11 being arranged upstream of the reels 5, 6 and 7.
  • the system shown for hot rolling strip or sheet-shaped rolling stock differs from conventional hot rolling systems of a comparable type primarily in that the roughing stand 3 is arranged in front of the two reversing stands 4 serving as finishing stands with the smallest possible distance, so that between the roughing stand 3 and the front reversing stand 4 the reversing reel 5 just finds space.
  • This not only makes the usual roller table for receiving the tape for the preliminary stitches unnecessary, but also gives the advantage that all scaffolding can be switched from an individual operation to a joint operation or a tandem operation.
