Definitions

  • the invention relates to a method for producing rolled or cast metal strips, especially steel strips made of stainless steel and titanium alloys, with a descaled Surface, after which the metal strip in question is annealed, for mechanical pre-descaling and for chemical and / or electrolytic descaling is stained.
  • Such a treatment method is known, according to which the metal strip in question in the course of producing a descaled strip surface first annealed, then for mechanical Pre-descaling straightened and then is blasted and / or brushed, and then to chemical descaling to be pickled so that finally a metal or steel band with a clean one Belt surface is available.
  • the glow serves in the general for the elimination of work hardening. -
  • the Blasting and / or brushing the metal strips is proportional in terms of time and plant technology investment-intensive. The necessary ones Blasting systems and brush machines cause considerable Maintenance and operating costs.
  • EP 0 695 808 A1 discloses one of these Method or such a device, according to the preamble of claim 1 or 2.
  • the invention has for its object a method for Manufacture of rolled or cast metal strips, especially steel strips made of stainless steel and titanium alloys, the embodiment described above create what the descaling in cost-reducing Way is optimized. In addition, one should be carried out suitable band line can be created using this method.
  • the invention solves this problem with a generic one Procedure in that the stretch bending straightening immediately before annealing and pickling immediately after annealing be made. Immediately means within the scope of the invention without the interposition of further treatment measures. - Surprisingly, the mechanical pre-descaling significantly better if the stretch bending judging before the glow takes place. It has been found that the metal straps and especially stainless steel straps so well be pre-descaled that they are without blasting and / or brushing Driven at maximum speed in the belt line can and still the strip surface after pickling is perfectly clean. In this respect, according to the teaching of Invention optimized descaling throughout Descaling process rationalized in a cost-saving manner becomes.
  • the one for performing the invention Band treatment line particularly suitable for the process with at least one decoiler, one Stretch bending straightening device for mechanical pre-descaling, a glow, a chemical and / or electrolytic pickle Post-descaling and a take-up reel characterized in that the stretch bending straightening device in Direction of strip running immediately before the annealing and pickling is located immediately behind the glow. Right away means in this context without the interposition of others Belt processing units.
  • a belt treatment line according to the invention without a blasting system and brushing machines is also advantageous when except hot-rolled and also cold-rolled strips annealed and pickled Need to become. Because usually when switching the strip treatment line from hot strip to cold strip the otherwise necessary blasting system is cleaned, thus no blasting material the smooth surface of the cold strips can damage. This also applies to different roles.
  • the associated production downtimes are eliminated in the belt treatment line according to the invention.
  • a tape store can be provided on the inlet side in front of and / or behind the stretch bending straightening device be arranged. By using such tape storage standstill marks are avoided in the area The stretch bending rolls can occur if the one in question Metal band in the infeed area for the purpose of changing the waistband or welding a subsequent metal strip is stopped. Because the tape storage allows you continuous belt pass. The can before Straightening straightening device arranged inlet storage so be chosen small that the stretch bending straightening device during the belt standstill in the inlet only in crawl mode continues. Under this condition, tape running and marking problems are negligible.
  • the stain can be a skin pass mill and / or a stretch bending straightener may be subordinate to in relation for flatness, surface roughness and gloss each to be able to achieve the required properties.
  • the skin pass mill can be equipped with textured rollers if patterned or defined belt surfaces are desired. Otherwise there is the possibility of the metal strip in question after descaling by stretch bending straightening or to split and / or trim before winding.
  • the single figure shows a schematic representation a strip treatment line with a decoiler 1, one Welding machine 2, a bend straightening device 3, an annealing furnace 4, a pickling 5 and a take-up reel 6.
  • the stretch bending straightening device 3 is in the tape running direction immediately before the glow 4 and the Pickling 5 arranged immediately behind the glow 4.
  • Tape storage 7, 8 may be arranged, which is only indicated is.
  • a tape storage 9 is located regularly also behind the stain 5.
