Abstract (en)

[origin: EP3438318A1] Provided is a method for producing a molten aluminum-plated steel wire in which a steel wire (2) is immersed in a molten aluminum plating bath (1), the resulting molten aluminum-plated steel wire (3) is subsequently pulled up from the molten aluminum plating bath (1) and a stabilizing member (11) is brought into contact with the bath surface (10) of the molten aluminum plating bath (1) and the molten aluminum-plated steel wire (3) at the boundary between the molten aluminum-plated steel wire (3) and the bath surface (10) of the molten aluminum plating bath (1), a nozzle (12) for blowing an inert gas is arranged in a position facing the stabilizing member (11) with the molten aluminum-plated steel wire (3) therebetween, and an inert gas is blown from the tip (12a) of the nozzle (12) toward the boundary at a pressure of 0.1-20 kPa.
