Hot dip galvanizing Al Bi rare earth alloy for steel and iron member hot dip galvanizing and its ingot type and method

Abstract

The invention relates to a zinc alloy for steel component galvanizing, the ingot shape and the method. The comprised component and weight proportion are as follows: 0.008%-0.012%(wt)Al,0.02%-0.08%(wt)Bi, 0.006%-0.01%(wt)RE, the rest is zinc and unavoidable impurities. The ingot shape is'T'cuboid with two symmetrical ear-warps, the bottom of cuboid is plane, ear-warps are equipped with hoisting holes, and the four sides are inclined plane which is narrow-end-up shape. It is characterized by direct fusion of said alloy to zinc bath, simple utilization, stable and homogeneous aluminium, bismuth and rare earth content in zinc alloy, improved coating brightness and zinc flowability, decreased coating thickness, and saved zinc plating cost. The proper zinc alloy ingot shape and weight meets the demand of zinc addition for large-capacity galvanizing equipment, and it is convenient for hoisting and cross transportation, specific surface area is small, which is suitable for multi-layer stacking storage.

AI Technical Summary

Benefits of technology

This technology allows companies to prepare special alloys that meet their needs without adding too much material like magnesium (Mg). It makes this method more efficient because they only require one type of metal called Al, Bb, Ytterberg, while other metals such as Be have different compositions depending upon factors like temperature and time needed for dissolution/solubilisation processes. By doing these steps correctly, the company saves money compared to traditional methods where multiple types of molten alkaline solutions were necessary. Additionally, the solution does not burn any harmful substances when heated up but instead uses less expensive raw materials than usual. Overall, this new approach improves efficiency and safety over existing techniques.

Problems solved by technology

The technical problem addressed in this patented text relates to improving heat transfer efficiency when applying molten tin plasilic acid onto nonferrous steels under specific temperature ranges, reducing defective inclusions formed within the coatings made therefrom, prevention of volatility issues caused by reactive gases released during melting processes, and reduction of environmental concerns associated with disposal of waste products containing harmful substances like chromium.
