  • the zinc coating ensures high corrosion resistance. This is the larger, the thicker the coating is.
  • the red test carried out on a bare, unpainted sample in accordance with DIN 50021 results in red rust already after 24 hours at a coating run of 25 g / m 2 , while red coating occurs at a coating application of 70 g / m 2 after 120 hours arises.
  • the thickness of the coating required in the prior art for sufficient corrosion resistance involves problems in weldability. This is especially true if by laser welding at high welding speeds through-welding in the lap joint is to be generated without minimum gap, such as it is particularly required in the field of the construction of automobile bodies or in the field of home appliances.
  • the seam produced by such a weld should be free of through holes, have a substantial crater freedom and have no open pores.
  • the zinc bath is surrounded by an enclosure.
  • An example of such an approach is in the US 4,369,211 described.
  • a housing for the melt bath is provided, in which a controlled atmosphere with an oxygen content of 10 ppm and more prevail, so that no metal vapor is formed or slag can form. It is emphasized that with gases that do not contain oxygen, slag formation can not be prevented.
  • the object of the invention was to provide a method that allows the production of a flat steel product with simple means, which has an optimum combination of high corrosion resistance and optimized weldability and which is particularly suitable for use as Material suitable for the automotive body construction or for the construction of household appliances.

  • a hot-dip-coated flat steel product according to the invention has surprisingly good corrosion resistance at a maximum coating weight of 25 g / m 2 per side, minimized in comparison with the prior art.
  • the low coating weight and the associated low thickness of the coating of a maximum of 3.5 microns each side in combination with the high corrosion resistance makes inventive sheet or strip particularly suitable for the production of components that are produced by welding individual sheet metal elements.
  • elements for automobile bodies or home appliance technology can be produced with sheet steel produced according to the invention by welding the individual sheet metal parts formed from sheet metal or strip according to the invention by laser welding at high welding speeds economically and with optimum results.
  • the corrosion resistance of a steel strip or sheet produced according to the invention is determined on the basis of a salt spray test according to DIN 50021-SS in a Korrosionskortzeitprüfclar on bare, unpainted steel sheet in which continuously a neutral 5% NaCl solution at a temperature of 35 ⁇ 2 ° C than attacking agent is sprayed in a chamber.
  • the steel sheet samples are doing in the chamber with a Inclined angle of 65 to 75 ° to the horizontal. In practical tests carried out in this way, it has been found that sheets and strips coated according to the invention regularly show first red rust formation only after a test duration of 300 hours.
  • the magnesium content contained in the melt intended for the coating is found essentially unchanged in the coating.
  • the Al content of the coating in the finished steel strip according to the invention is generally 1.8 to 3.2, in particular 2 to 3 times, higher than in the melt.
  • Optimum corrosion protection is achieved if the coating has a Mg content of 0.4-1.0% by weight, in particular at least 0.5% by weight.
  • the melt preferably contains less than 0.15% by weight of aluminum. Practical Al contents of the melt in this case are in the range of 0.12-0.14% by weight.
  • the Al content of the melt is preferably at least 0.15% by weight.
  • a full-scale coating comprising a 20 ⁇ m thick cathodic dip coating, a 32 ⁇ m thick surfacer coat layer applied thereto and a 40 ⁇ m thick basecoat film was applied to a steel sheet sample produced according to the invention after alkaline cleaning and phosphating.
  • the bending over the conical mandrel performed neither at room temperature nor at -20 ° C to a detachment of the paint layer.
  • a steel fine strip in a galvanizing plant which is traversed at a strip speed of typically 60 to 150 m / min, is subjected to a continuously running strip hot-dip galvanizing process.
  • the sheet or strip to be galvanized is first annealed in a furnace, for example a DFF furnace (Direct Fired Furnace) or, preferably, a RTF furnace (Radiant Type Furnace). Following the oven passes through the sheet or Tape the reduction furnace section, where it is kept under a protective gas atmosphere with 3.5 - 75% hydrogen.
  • the temperatures achieved during annealing are in the range of 720 - 850 ° C.
  • the thus annealed strip or sheet is then passed through a so-called proboscis under exclusion of air in the zinc bath, by a 0.05 to 0.30 wt .-% Al and 0.2 to 2.0 wt .-% Mg, in particular 0.4 to 1.0 wt .-% or 0.5 to 1.0 wt .-%, remainder zinc and unavoidable impurities containing melt is formed.
  • the thickness of the coating is limited in a conventional manner by means of stripping nozzles to a value of 3.5 microns maximum page, so that the resulting flat product according to the invention, the maximum coating weight to 25 g / m 2 per side is limited.
  • an inert gas stream is passed over the bath surface.
  • This inert gas stream may originate from the wiping nozzles used to adjust the coating thickness, or may be discharged from separate nozzles which disperse the inert gas over the bath surface. Nitrogen is particularly suitable as inert gas for this purpose.
  • Slag formation can also be reduced by raising the bath temperature to a range of 380-450 ° C is set.
  • the belt temperature during immersion can be limited to 360 - 500 ° C in order to minimize the tendency to oxidation, especially in the immersion area.
