  • the temperature control according to the invention in step a) prevents that during the heating essential alloying constituents diffuse to the surface of the flat steel product.
  • the diffusion of alloy constituents to the surface is particularly effectively suppressed so that an effective iron oxide layer can be formed in the following step , This prevents further alloying constituents from diffusing to the surface during the subsequently increased annealing temperature.
  • a pure iron layer can be formed which is suitable for a full-surface and firmly adhering coating of zinc and / or aluminum is very suitable.
  • the work result can be optimized by completely reducing the iron oxide layer produced in the oxidizing atmosphere to pure iron. In this state, the coating also has optimum properties with regard to its deformability and strength.

  • the thickness of this iron oxide layer can be detected optically, the result of the measurement being used to set the respective oxygen content of the zone 5b.
  • the chamber volume is correspondingly small. Therefore, the reaction time for a change in the composition of the atmosphere is small, so that on a Changing the belt speed or to a different thickness of the target thickness of the oxide layer by a corresponding adjustment of the oxygen content of the prevailing atmosphere in the zone 5b can be reacted quickly.
