Definitions

  • the invention relates to a method for rolling strip-shaped rolling stock, wherein the metal strip first passes through a pickling line and then between two reversing a reversing mill, and wherein the end of a metal strip is welded before the pickling line with the beginning of a subsequent metal strip and before the coiling of finished Rolled metal strip is a separation of the welded metal bands.
  • Metal strip pickling lines and rolling mills are available as standalone or coupled systems.
  • Coupled systems are generally equipped with at least 3 rolling stands, whereby the maximum decrease in the rolling stock is limited.
  • the investment costs here are very high, which prove to be economical only by the high production volume.
  • the coils are rolled several times reversibly in single stands.
  • the strip beginning of the next coil is welded to the end of the strip, thus eliminating threading for the next coil.
  • Individual pickling lines usually have one or two rewinders with coil cars and coil shelves, as well as reversing systems and a stocking station with coil cars and coil shelves.
  • EP 1701808 BI is a method and a system for rolling strip-shaped rolling known, with a reversing mill and before and after arranged reel for winding the metal strip, a pre-switched pickling line and an upstream of this welding machine for welding together of tape end and beginning of tape.
  • the object of the invention is to make the process for rolling strip-shaped rolling stock, in particular metal strip, more economical.
  • the invention is thus based on the core idea of connecting the band ends of coil and a Reversierwalzgerüst, usually consisting of several consecutively arranged rolling stands, via a tape storage as a material storage for the period of finish rolling of the previous coil to supply.
  • a coupled, continuous pickling / rolling process is achieved.
  • the beginning of the strip is rolled with the end of the strip of the previous coil at the end of the first stitch for the length necessary to cover the length of anvil to train.
  • this beginning of the tape is also reversed until the previous coil is cut off in order to feed it to the reversing reel 2.
  • this band start of the current coil remains in the band memory until the previous coil is completely reversed.
  • the tape storage is made large in order to bridge the time for finish-rolling the previous coil.
  • the pickle is again designed in its process speed so that the production quantity is equal to the maximum production quantity of the reversing plant.
  • Another advantage is the savings of the federal warehouse and the coil transport facilities in the outlet part of the pickling and the coil preparation of the reversing plant. This also eliminates the damage to coil that occur during transport.
  • the tape A emerging from the pickling plant passes through the two rolling stands 3, 4 and is then rewound on the reversing reel 1. ( Fig. 1 )
  • Fig. 2 In the Fig. 2 is the band B shown in phantom. It is clear from this Fig. 2 and the other Fig. 3 in that the strip beginning of the strip B also runs onto the reversing reel 1. During the subsequent reversing, the band B is separated from the band A by the scissors 6, so that the already rolled-in beginning of the band B remains on the still unrolled remaining band B. ( Fig. 4 )
  • Fig. 6 shows again the beginning of a new pickling / rolling sequence with the bands B and C.
  • the nip may be open, so that the rollers are active only when the incoming to the rolled strip beginning non-rolled strip part.
  • the subsequent metal strip can be stored in a strip accumulator 7.

Claims (3)

  1. Procédé pour le laminage d'un feuillard, dans lequel on fait passer le feuillard d'abord par une ligne de décapage (5) et ensuite à travers un laminoir réversible entre deux bobineuses réversibles (1, 2), et dans lequel on soude la fin d'un feuillard avant la ligne de décapage (5) à l'amorce d'un feuillard suivant et, avant le bobinage du feuillard laminé prêt à l'emploi, on procède à une séparation des feuillards soudés l'un à l'autre, caractérisé par le scénario suivant :
    - le feuillard A qui quitte la ligne de décapage (5) passe par les deux cages de laminoir (3, 4) du laminoir réversible et vient ensuite s'enrouler sur la bobineuse réversible (1) montée à la suite du laminoir réversible ;
    - dans lequel, à la fin du feuillard A avant son entrée dans la ligne de décapage (5), l'amorce d'un feuillard suivant B a déjà été soudée ;
    - cette amorce du feuillard B est alors laminée de manière conjointe et, en fait, sur une longueur qui correspond à la longueur d'amorçage du bobinage jusqu'à l'obtention d'une traction sur la bobineuse et qui s'étend également sur la bobineuse réversible (1) ;
    - lors de la réversion qui s'ensuit, le feuillard B est séparé du feuillard A par une lame de coupe (6) de telle sorte que l'amorce du feuillard B déjà laminée subsiste contre le reste du feuillard B qui n'a pas encore été laminé ;
    - on procède ensuite au laminage réversible du feuillard complet A, celui-ci, après sa sortie du laminoir réversible, venant s'enrouler sur la bobineuse réversible (2) montée en amont de la cage réversible ;
    - dès que le feuillard A se trouve complètement sur la bobineuse réversible (2), le feuillard B est acheminé au laminoir réversible et les scénarios indiqués ci-dessus se répètent avec ce feuillard B et un feuillard suivant C.
  2. Procédé selon la revendication 1, caractérisé en ce que lors de l'enfilage de l'amorce déjà laminée du feuillard B ou par après C, la fente de laminage du laminoir réversible reste ouverte, si bien que le laminage ne devient actif qu'à l'entrée de la partie de feuillard non laminé qui fait suite à l'amorce laminée.
  3. Procédé selon l'une quelconque des revendications précédentes, caractérisé en ce que, au cours du laminage réversible d'un feuillard entre la ligne de décapage et la lame de coupe pour la séparation des feuillards, on procède à un stockage du feuillard suivant dans un dispositif de stockage pour feuillard.
