Definitions

  • the invention relates to a system for flexible and economical pickling and Cold rolling of metal strips, according to the preamble of claim 1 and a working method according to the preamble of claim 4.
  • the reversing rolling mill can be designed as a conventional reversing stand or as a 2- to 3-stand tandem stand group with reversing reels arranged on both sides of the tandem stand group. As soon as the reversing reel of the reversing stand has taken over the strip, the reel dome of the reversible reel is free for a new coil coming from the metal pickling line.
  • the Cold rolling takes place on a reversing rolling mill, in which after the work steps a, b or d is produced and rolled out in several reversing stitches is, the band after one or more reversing stitches to at least one of the reversing reels arranged on both sides of the reversing rolling mill is wound up.
  • a system designed according to the invention for carrying out the working method is extremely variable, needs a minimum of operating personnel, needed little space, has low investment costs and shows its greatest economy Use of thin hot strip, as is increasingly being the case Thin slab plants or strip casting plants is produced.
  • the tape B unwound from a decoiler 1 is prepared in the usual way via the driving roller set 2 of the metal pickling 3 designed as thrust pickling Processing forwarded.
  • the metal stain 3 is on the output side behind the conventional finishing devices 4 such as scrubbers, scrap shears and partial shears equipped with a horizontal reel 5 on which the stain leaving band B is wound up.
  • the reversible reel 5 has one Take-up reel dome 6 and an unwind reel dome 7 with separate drives, i.e., each reel dome has its own drive unit, which is preferred when turning is uncoupled.
  • Decoiler and decoiler are axial in the housing slidably arranged so that each of the metal pickle 3 facing away Decoiler 7 the coils 8 wound behind the metal pickle 3 in the middle of the subsequent reversing mill 9 can handle regulated again.
  • the reversing mill 9 consists of a traditional reversing stand, which the coil 8 takes over the reversing reel 10 after the first reducing stitch.
  • the Unwinding reel dome 7 of the reversible reel 5 is then free for exchange with the Winding reel dome 6 and the metal pickle 3 is available again.
  • the reversing frame 9 can, as shown in the lower half of the drawing a 2 to 3-stand tandem mill with stands 9a and 9b. These are preferably in 6-high construction (the relatively small work rolls are over Intermediate rolls and back-up rolls supported) for high reductions (over 50% in first scaffold) designed so that part of the pickled strips B in one Let the passage roll. In this case, as shown, the vehicle is "run over" Reversible reel 5 possible in so-called endless operation.
  • the metal pickle 3 in the resulting breaks, so-called non-cold-rolled P.0. coils create.
  • the band B is in this case behind the metal pickle 3 on the Wind-up reel dome 6 of the reversible reel 5 and wound as a finished product submit.
  • coils can also be used during longer breaks Reversing roll mill 9, for example when changing the backup roll, are pickled.
  • the flexibility of the system also makes it possible to plan planned shutdowns in the Roll out metal pickling 3 coils 8 previously pickled in the reversing mill 9. These coils 8 are fed to the decoiler 7 of the turning reel 5 and handled there, fed to the reversing mill 9.
