Definitions

  • the invention relates to a method for rolling strip-shaped rolling stock, in particular metal strip,
  • the metal strip passes first through a pickling line and then through a reversing mill between two reels, and wherein the end of a metal strip is welded to the beginning of a subsequent metal strip before the pickling line and a separation of the welded to each other before the finish rolled metal strip Metal bands done.
  • 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 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.
  • the object of the invention is to make the process for rolling strip-shaped rolling stock, in particular metal strip, more economical.
  • metal strip passes first through a pickling line and then through a reversing mill between two reels, and wherein the end of a metal strip is welded to the beginning of a subsequent metal strip before the pickling line and a separation of the welded to each other before the finish rolled metal strip
  • Metal straps are made by the following procedure:
  • the metal strip A emerging from the pickling line passes through the two rolling stands of the reversing rolling stand and is then reeled on the reversing reel following the reversing rolling mill,
  • Metal strip B remains on the still unrolled remaining metal strip B, - Then followed by the reversing rolling of the complete metal strip A, which runs after exiting the reversing on the Reversiergerüst upstream Reversierhaspel, - as soon as the metal strip A is completely on the Reversierhaspel (2), the metal strip B is fed to the reversing mill and it the above procedures are repeated with this metal band B and a subsequent metal band C.
  • the invention is thus based on the core idea of connecting the band ends of coil
  • Reversierwalzgerüst usually consisting of several rolling mills arranged one behind the other, via a strip storage as a material storage for the period of finish rolling of the previous coil to supply.
  • the tape storage is made large in order to bridge the time for finish-rolling the previous coil.
  • the pickle is again designed so that the production quantity equals the maximum production quantity of the reversing system. Advantages here are shortest string follow-up times, and less dimensional length, since the beginning of the tape is already reduced by two rolling in the strip thickness.
  • Another advantage is the saving of the bundle bearing as well as the coil transport facilities in the outlet part of the pickling line and the coil preparation of the reeving plant. This also eliminates the damage to coil that occur during transport.
  • 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 beginning of a band C had been welded, so that the pickling / rolling process can again run continuously for these two bands.
  • the nip When threading the already rolled strip beginning of the strip B or later then C, the nip may be open, so that the rollers are active only when the incoming to the rolled strip beginning non-rolled strip portion.

Abstract

L'invention concerne un procédé de laminage d'un produit à laminer en forme de bande, notamment d'une bande métallique. Ce procédé est caractérisé en ce qu'il se déroule sensiblement de la manière suivante : la bande métallique A sortant de la ligne de décapage pénètre dans deux laminoirs (3,4) de la cage réversible, l'amorce d'une bande métallique B suivante ayant déjà, avant même son introduction dans la ligne de décapage (5), été soudée à l'extrémité de la bande métallique A, cette amorce de la bande métallique B étant alors co-laminée, à savoir sur une longueur qui correspond à la longueur d'enroulement jusqu'au montage de traction sur le tourniquet, et défilant également sur le tourniquet réversible (1). Lors du renversement consécutif de la marche, la bande métallique B est séparée de la bande métallique A de telle façon que l'amorce déjà laminée de la bande métallique B demeure sur le reste non encore laminé de la bande métallique B; enfin, se produit le laminage réversible de la bande métallique A complète.
