摘要： By first fluxing a steel long product with novel specific flux compositions, it is possible to continuously produce, more uniform, smoother and void-free galvanized coatings on such steel long products in a single hot dip galvanization step making use of zinc-aluminum alloys or zinc-aluminum-magnesium alloys with less than 95 wt. % zinc. This is achieved by providing potassium and sodium chlorides in a KCl/NaCl weight ratio of at least 2.0 in a flux composition comprising (a) more than 40 and less than 70 weight % zinc chloride, (b) from 10 to 30 weight % ammonium chloride, (c) more than 6 and less than 30 weight % of a set of at least two alkali metal chlorides.

摘要： A flux composition for treating a metal surface prior to batch hot galvanizing in molten zinc-based alloys is disclosed. The flux composition can include (a) 40 to 70 wt. % zinc chloride, (b) 10 to 30 wt. % ammonium chloride, (c) 6 to 30 wt. % of a set of at least two alkali or alkaline earth metal halides, (d) from 0.1 to 2 wt. % lead chloride, and (e) from 2 to 15 wt. % tin chloride, provided that the combined amounts of lead chloride and tin chloride represent at least 2.5 wt. % of the composition. A fluxing bath having this flux composition dissolved in water for use in galvanizing processes, as well as, a method for continuous or batch-wise treatment of metal articles in order to produce a protective coating layer with a thickness ranging from 5 to 30 μm is also disclosed.
