Title:
The continuation galvanization method for steel products
Document Type and Number:
Japanese Patent JP6133753
Kind Code:
B2
Abstract:
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 specific amounts of lead chloride and tin chloride in a flux composition comprising (a) more than 40 and less than 70 wt.% zinc chloride, (b) from 10 to 30 wt.% ammonium chloride, (c) more than 6 and less than 30 wt.% of a set of at least two alkali or alkaline earth metal chlorides.
