  • the invention relates to a method for producing steel strip for through Deep-drawn or ironing parts made using a hot strip multi-stage and cold formed with a cold rolling degree of at least 86% is, with at least one side of the strip material with a galvanic produced coating containing Ni, Co, Cu, Fe, Sn, In, Pd, Bi and / or their Alloys is provided.
  • Cold-rolled steel strip is used for the production of rotationally symmetrical cold formed parts such as B. battery sleeves used.
  • the at the The processes used for cold forming are deep drawing and on the other hand, ironing, the latter also as a DI process (drawing and ironing).
  • a steel sheet is also used to achieve an almost isotropic forming with small thickness tolerances in a texture-free and homogeneous rolled strip or sheet needed.
  • DE 20 19 494 A discloses a process for the production of corrosion-resistant coated steels.
  • hot-rolled Steel strip is a coating of at least one metal, which is made of Co, Cu, Ni and Ti composing group applied, and the hot rolled Steel strip is then with the coating on it on the desired Gauge block cold reduced. You can do this in one or more stages Cold reduction process Reduction levels of around 90% and more can be achieved.
  • the cold reduced steel strip is annealed for recrystallization, the annealing is preferably carried out in a continuous annealing process.
  • a box annealing process can be required just a single annealing step Find use, the annealing temperature in a range between 566 and 621 ° C for a period of between 1 and 5 hours. This happens to an alloying of the by vapor deposition on the hot strip applied coating with the metal of the hot strip in an excessive prevent strong measure.
  • the annealing temperature in a range between 566 and 621 ° C for a period of between 1 and 5 hours. This happens to an alloying of the by vapor deposition on the hot strip applied coating with the metal of the hot strip in an excessive prevent strong measure.

  • GB 2 101 156 A describes a method for producing a steel strip for deep drawing.
  • the method described in this document includes conventional hot rolling and cold rolling steps, which are based on an aluminum alloy Steel can be applied.

  • the steel strip is annealed in accordance with this Print only using the continuous annealing process.
  • JP-A-2 267 242 describes a method for producing a cold rolled one Steel strip made of aluminum-soothed steel with low carbon content.
  • the nitrogen contained in the steel in the form of Aluminum nitride binds after pickling and subsequent to the hot rolling Cold rolling steps are used to anneal the steel strip in a box annealing process.
  • the steel band does not have a coating, just as little contains the steel boron.
  • the object of the invention is therefore to develop a method of the generic type which, with regard to the anisotropy, comes very close to the material properties achieved by normalizing, but at the same time can be operated at relatively lower production costs and manages with as few process steps as possible. After annealing, a globular grain is to be achieved, and the steel strip produced by the process according to the invention should not have any disadvantages due to aging or higher mechanical-technological values at high rolling degrees.

  • the limit values for the yield strength between the edge and the center of the strip vary by less than 15 N / mm 2 .
  • the hot-rolled strip is then pickled and then one or two subjected to two-stage cold rolling.
  • the degree of cold rolling is 86% or more.
  • the starting material with a thickness of 1.2 to 8 mm can be in this way cold roll to a final thickness of 0.1 to 1.0 mm.
  • Cold rolling there is a recrystallization annealing in the coil i.e. an annealing of the strip in the wound state.
  • recrystallization annealing comes to you Normal annealing, as is usually the case in continuous furnaces with stretched strip is carried out in the effects very close. Closes after coil annealing re-rolling the strip to improve its surface and adjust the mechanical-technological values.
  • the steel strip is galvanized with at least one of its two surfaces manufactured cover provided.
  • This can be Ni, Co, Cu, Fe, Sn, In, Pd, Bi and / or their alloys contain.
  • As part of the whole Process flow can be the electrolytic finishing on the first or on connect the second stage of cold rolling, followed by another Steps, the annealing in the coil and the rolling of the strip are carried out. A an additional annealing stage between the two cold rolling stages is also possible.
  • electrolytically finished strip can also be used non-metallic or galvanic coatings, so to achieve special effects and properties.
  • the thickness of the entire electroplating on one or both sides of the Steel strip should be 0.1 ⁇ m to 8 ⁇ m.
  • the parameters are used to achieve a low lobedness of the steel strip set during the cold rolling so that following the simple Annealing in the coil an ansiotropy ⁇ r of max. +/- 0.12 gives what a relative Tip height of max. Corresponds to 2.5%. This also arises for the later Deep drawing or ironing advantageous round grain structure made of globular Grain a.
