Abstract

The invention discloses a Ba-Ca-Mn zinc alloy for top slag type corrosion-resistant hot-dip galvanizing as well as a processing process of the. The Ba-Ca-Mn zinc alloy comprises the following components in percentage by weight: 0.2-0.3 wt.% of Ba, 0.2-0.4 wt.% of Ca, 1.2-1.8 wt.% of Ge, 0.2-0.4 wt.% of Ni, 1.4-1.6 wt.% of Mn, 0.1-0.2 wt.% of V and the balance of zinc. The material can be applied to hot-dip galvanizing of a steel plate at 320 to 340 DEG C; furthermore, zinc slag formed in the hot-dip galvanizing process has low density, floats above zinc liquid and is convenient to fish. Through the alloy industrialization, great economic and social benefits can be obtained. Along with the development of more engineering application fields, the novel alloy will be certainly and widely applied to more hot-dip galvanizing.
