Definitions

  • the invention relates to a method for inscribing hot steel blocks, onto which a metallic material which prevents the desired steel properties from being impaired is applied in a punctiform or linear manner by flame spraying.
  • the invention is therefore based on the object to avoid these deficiencies and to improve a method of the type described with simple means so that the steel blocks can be labeled permanently and legibly even with comparatively high surface temperatures.
  • the invention solves the problem in that a nickel or iron powder having a maximum grain size of at most 0.075 mm is used as the metallic material, which at the same time with a maximum of 10% by weight of the metal powder constituting zirconium oxide or aluminum oxide powder with a maximum grain size of at most 0.075 mm is applied by flame spraying.
  • the advantage is initially achieved that the materials used do not have to form a deformable alloy, as is the case with wires, so that oxides also have a color different from iron oxide can be used.
  • the point or line sprayed-on metallic material can be permanently colored, so that otherwise unsuitable nickel or iron can be used for this purpose Melting point is significantly above the average surface temperature of the steel blocks.
  • it must be ensured that there is a sufficient adhesive bond between the sprayed-on metallic material and the zirconium or aluminum oxide, which requires special measures.
  • zirconium oxide or aluminum oxide into the matrix of the sprayed-on metal powder limits what must be taken into account by restricting the proportion of zirconium oxide or aluminum oxide powder that can be sprayed with the metal powder.
  • nickel powder with a pure nickel content of at least 98% by weight is used as the nickel powder.
  • Commercial iron powders have a pure iron content of, for example, 95% by weight.
  • Commercial zirconium oxide powders have a weight fraction of at least 65% ZrO2, the remainder CaO, while with commercially available aluminum oxide powders a weight fraction of 95% of Al2O3 can be expected.
  • These commercially available powders can be used advantageously in the specified weight ratio for marking steel blocks by blowing them through an acetylene flame with the help of oxygen in a spray gun.
  • the oxygen is fed to the spray gun at a pressure of usually 1.5 bar.
  • the acetylene gas fed to the spray gun has a pressure of approximately 0.5 bar.
  • the distance between the mouth of the spray gun and the surface of the steel blocks to be labeled must be selected at least in accordance with the length of the acetylene oxygen flame emerging from the spray gun, which is increased by a distance of 10 mm.
  • the distance that extends beyond the flame length is likely to be necessary to take into account the time course of the melting of the particle surfaces. If this distance between the end of the flame and the steel block surface is kept between 10 and 20 mm, advantageous conditions are ensured not only with regard to the adhesive effect but also with regard to the line width of the lettering.
  • the proportion of the powder of zirconium oxide or aluminum oxide which is simultaneously sprayed on with the metal powder should not exceed 5% by weight of the metal powder.
  • a weight fraction of 97% of commercially available nickel powder and 3% of commercially available zirconium oxide powder has proven to be a favorable ratio for most applications.
  • An amount of at most 2% by weight of an aluminum powder can additionally be mixed with the nickel or iron powder in order to improve the adhesion of the lettering to the surface of the steel block.
  • the low-melting aluminum powder has an adhesion-promoting effect. In this context, it should also be taken into account that part of the aluminum burns at surface temperatures of approx. 800 ° C and the resulting heat supports an advantageous sintering of the high-melting metal powder on the surface of the steel block.
