Abstract (en)
[origin: WO2024002821A1] The invention relates to a device (150) for applying a layer (10) to a front and/or rear side of a flat steel product (100), comprising: a zinc-alloy melt pool (11) with an inlet side (E) and an outlet side (A); a stripping nozzle device (14) with at least one gas nozzle (15) for blowing off the front or rear side of the flat steel product (100) with gas (G), wherein the stripping nozzle device (14) is arranged in the region of the outlet side (A); a water vapour device (50) which is designed to output gaseous water vapour and to provide a controlled water vapour atmosphere in the proximity (NB) of the front and/or rear side of the flat steel product (100), wherein the controlled water vapour atmosphere has an absolute local humidity that is greater than 1 g/m³ and lower than 300 g/m³.
