Definitions

  • the invention relates to an improved process for the preoxidation of oxidation-sensitive steel strip in a reaction chamber arranged in a furnace chamber, in order to thereby set suitable surface properties of the strip steel to be coated for a directly following hot-dip coating.
  • the surface, formed by the selective oxidation manganese, silicon, and / or aluminum oxides affect the wettability of the strip surface with a molten coating metal (for example, zinc), with the result of defects (so-called bare spots) or a poor the coating with the tape surface.
  • the alloy composition is decisive for the coating problems on high-strength steel, in particular the tendency to form non-reducible oxides at the surface. This applies, for example, to the following steel grades:
  • DE 102 004 059 566 describes a process in which the strip is pre-oxidized.
  • the method described in this document can be summarized as follows:
  • the reaction chamber with a strongly oxidizing atmosphere inside, is located in the furnace chamber of a continuous furnace with a hydrogen-containing, reducing atmosphere.
  • the belt inlet and belt outlet into the reaction chamber must be sealed to the greatest possible extent against gas exchange.
  • On Gas transfer from the furnace into the reaction chamber causes the penetrating hydrogen at least partially consumes the oxygen required for the oxidation and impairs the nature of the desired oxide layer on the strip surface. This problem is exacerbated by the lower the oxygen content in the reaction chamber.
  • a gas transfer from the reaction chamber into the furnace causes a higher water content (dew point) in the furnace and thus an increased oxidation potential. This is particularly disadvantageous for very high-strength steels with a higher content of oxygen-affine alloying elements.
  • the strip temperature is the decisive parameter for process control. This is preferably between 650 and 750 ° C. As long as the oxygen content is> 1% and the treatment time> 1 s, their influence on the thickness of the oxide layer formed is negligibly small. With oxygen contents in the range 2 to 5%, an insensitive process can be assumed.
  • this object is achieved by the features specified in claim 1, in particular by sealing the reaction chamber at a belt inlet and a belt outlet against gas exchange between the furnace chamber and the reaction chamber and a gas which oxidizes Atmosphere in the reaction chamber is formed, introduced and the gas within the reaction chamber in a closed circuit is permanently circulated, the composition of which is regulated and losses compensated by leakage and consumption.
  • the reaction chamber is in principle sealed towards the furnace chamber and in particular at the belt inlet and belt outlet against gas exchange.
  • the atmosphere is constantly being circulated.
  • the gas is sucked out of the reaction chamber, cooled, fed to a fan, enriched with fresh air and fed back into the chamber. This achieves good atmospheric homogeneity.
  • nozzle systems at least one nozzle system
  • evenly supplied gas with high kinetic energy density with the aid of nitrogen as the carrier gas of the strip surface This is necessary in order to avoid laminar boundary layer effects.
  • the oxygen content of the atmosphere in the reaction chamber is a minimum of 1.5 to a maximum of 5% by volume.
  • the reaction chamber has a trigger.
  • this trigger is controlled so that the internal pressure of the reaction chamber corresponds to the pressure of the surrounding furnace atmosphere and so the gas exchange over the unavoidable leaks is minimal.
  • the oxidation-sensitive steel may contain at least a selection of fol gender alloying components: Mn> 0.5%, Al> 0.2%, Si> 0.1%, Cr> 0.3%.

Abstract

L'invention concerne un procédé pour l'oxydation préalable de feuillard d'acier hautement résistant. L'invention concerne un procédé amélioré pour l'oxydation préalable de feuillard d'acier hautement résistant dans une chambre de réaction disposée dans un espace de four. La chambre de réaction est fermée au niveau d'une entrée de feuillard et d'une sortie de feuillard contre un échange gazeux entre l'espace de four et la chambre de réaction et un gaz, qui forme une atmosphère oxydante dans la chambre de réaction, est introduit et le gaz est mis en circulation en permanence à l'intérieur de la chambre de réaction.
