FLUX AND PRODUCTION METHOD OF STEEL FORMED PRODUCT WITH HOT-DIP ZN-AL-MG COATING USING SAID FLUX
Provided is a technique that can produce a hot dip Zn-Al-Mg-based alloy coated steel product with a good plating appearance, without the need for heating of a steel product prior to immersion in a hot dip plating bath. Flux (11) for hot dip Zn-Al-Mg-based alloy plating contains: ZnCl2; and a low-rea...

Summary: | Provided is a technique that can produce a hot dip Zn-Al-Mg-based alloy coated steel product with a good plating appearance, without the need for heating of a steel product prior to immersion in a hot dip plating bath. Flux (11) for hot dip Zn-Al-Mg-based alloy plating contains: ZnCl2; and a low-reactive chloride which has low reactivity with respect to Mg in a plating bath and contains at least two chlorides selected from the compound group consisting of alkali metal chlorides and alkaline-earth metal chlorides, and a composition of the ZnCl2 and the low-reactive chloride is adjusted so that a liquidus temperature of the flux is 450°C or lower. |
