Definitions

  • the invention relates to a method of manufacture a scraping wire or brush wire according to the generic term of claim 1 (see e.g. JP-A-62238354).
  • wire brushes For the production of wire brushes, scrape tapes, Wire pins and the like are special wires Properties required.
  • the wire is said to be high Have strength and still be elastic.
  • Conventional Processes use unalloyed wire rods hardenable carbon steel using drawing tools are drawn to a predetermined diameter. In front the drawing process or between successive drawing steps there is a patenting, a heat treatment to restore the wire's drawability. After the wire is tempered when it is pulled to its final diameter, i.e. austenitized, printed and tempered to give him the to give necessary strength and straightness.
  • the wire has the smallest possible diameter before pulling having.
  • the raw wire is processed by rolling manufactured.
  • the diameter is therefore preferably included 6 mm or less.
  • the invention has for its object a method to specify for the manufacture of a scratch or brush wire, this without significant additional economic effort a wire that has a longer service life.
  • a wire rod alloyed with chromium is used used, the chromium content is less than 0.3%.
  • microalloyed steels Steels containing small amounts of alloy are also used referred to as microalloyed steels.
  • micro-alloyed prestressing steel with chrome and vanadium Provide steels to increase tensile strength.
  • prestressing steels have different properties as brush or scratch wire. Otherwise they are for steel alloys used for example prestressing steel not to the desired diameter with a drawable purely pearlitic / sorbitic structure.
  • vanadium through grain growth lose its effect.
  • the drawn Wire so tempered that the structure of the remuneration over the carbide precipitation shifted from the martensite to the bainite stage becomes.
  • the chromium content is preferably between 0.2 and 0.25%.
  • the starting steel wire used contains minor proportions of other alloy metals, such as manganese and / or silicon.
  • a scratching and Brush wire obtained with a pearlitic / sorbitic Structure is rollable, patentable and temperable, without the wear resistance due to the heat treatment is adversely affected.
  • wear resistance is the conventional scraping wire and brush wire clearly superior.
  • the deformability of the wire not less favorable. For example, for Manufacture of bristles for wire brushes or teeth for Scraper belts or the like require bending deformation, which with the manufactured according to the invention Allows wire to pass through easily.
  • the alloy element chrome finely dispersed as carbide in Steel is excreted and therefore significantly reduces wear works.
  • the production of a wire rod on the required small diameter for example by means of the so-called Stelmor process with pearlitic / sorbitic Structure, do not cause any difficulties.
  • Loosen the carbides rise and separate above the austenizing temperature finely dispersed on cooling. That is why crucial because the strength-increasing and wear-reducing Effect of those by the alloy elements carbides formed are not destroyed by particle growth may be.
  • the vanadium carbides would be caused by particle growth lose their strength-increasing properties.
  • a wire rod of 5.5 mm diameter used with a Carbon content of 0.68%, a silicon content of 0.25%, a manganese content of 0.75% and a chrome content from 0.2 to 0.25%.
  • the wire rod showed a pearlitic structure and could easily pulled to the patent size of 2.10 mm become. After patenting, the wire was on the Final dimension of 0.52 mm drawn.
  • the creep behavior of a brush wire can only in the brush to be judged. There were brushes with different Wires made as trimmings to the service life to test, using a brush on the market with Was rated 100%. Opposed to such a brush the attempt to extend the tool life by 40%.
