Abstract
A method of producing an Al plated steel wire comprises a first step of continuously immersing a material steel wire formed of a steel core into a molten Al plating bath and then withdrawing the material steel wire to a gas phase space. The material steel wire plated with a plating metal is brought into contact with a contact member at the plating bath rising portion to produce the Al plated steel wire, the Al plated steel wire having an average diameter DA (mm) and a minimum diameter DMIN (mm) in the longitudinal direction of the wire satisfying the following expression (1) (DA−DMIN)/DA≤0.10, (1). The Al plated steel wire is then wound.
