Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung von dünnem warmgewalzten Stahlband mit einer Enddicke < 1 mm aus bandförmig gegossenem Vormaterial in aufeinander folgenden Schritten, bei dem das

  • ≦ 90 mm dick gegossene Vormaterial nach dem Entzundern der Oberfläche auf der Tandem-Steckel-Gerüstgruppe in 6 Stichen gewalzt wird, wobei das Vormaterial nach dem ersten und zweiten Durchlauf in den den Steckel-Walzgerüsten nach- und vorgeordneten Steckelöfen aufgewickelt wird,
  • daß das Vorband nach dem dritten Durchlauf durch die Steckel-Walzgerüste in eine als Vorbandspeicher für das Vorband dienenden Wickeleinrichtung mit zwei übereinanderliegenden Öfen geführt und aufgehaspelt wird,
  • gleichzeitig mit dem Aufhaspeln des ersten Bundes ein zweites Bund aus dem Zwischenspeicher abgewickelt wird, dessen geschopftes vorderes Ende an das geschopfte hintere Ende des bereits abgewickelten Vorbandes angeschweißt wird,
  • das zu einem endlosen Band zusammengeschweißte Vorband durch einen zweiten Vorbandspeicher hindurch der Fertigstraße zugeführt wird, die das Vorband auf die gewünschte Fertigbanddicke reduziert.
Figure 00000001
The invention relates to a method for producing thin hot-rolled steel strip with a final thickness <1 mm from strip-shaped cast material in successive steps, in which the
  • ≦ After the descaling of the surface, the cast material, 90 mm thick, is rolled in 6 passes on the tandem-Steckel stand group, the feed material being wound up after the first and second pass in the Steckel furnaces downstream of the Steckel roll stands,
  • that after the third pass through the Steckel roll stands, the pre-strip is fed into a winding device serving as pre-strip storage for the pre-strip and has two superposed furnaces,
  • simultaneously with the reeling of the first bundle, a second bundle is unwound from the intermediate store, the cropped front end of which is welded to the cropped rear end of the pre-unwound strip,
  • the pre-strip welded together to form an endless strip is fed through a second pre-strip store to the finishing train, which reduces the pre-strip to the desired finished strip thickness.
