结构用热镀锌钢带的生产实践

Production Practice of Hot-dip Galvanizing Steels Used for Structure

采用LF精炼、ASP连铸连轧、可逆式冷轧、美钢联法连续热浸镀锌的工艺路线,通过合理设计钢的成分以及合理的轧制、热镀锌工艺,开发了结构用热镀锌钢带。实物质量检验表明,产品的力学性能、锌层组织及锌层附着性都达到标准要求,得到用户的认可,为更高强度结构镀锌板的开发提供了参考。

Using LF refinement, ASP continuous casting and rolling, tandem rolling and U.S. steel continuous galvanizing process route, through reasonable component design, rolling and hot-dip galvanizing processes, the hot-dip galvanized steel strips used for structure were developed. The physical quality inspection showed that the mechanical properties of the products and the structure and adhesivity of the zinc coated layer all met the needs of the Standard and the consumer’s approval, providing references to the development of the higher strength structure hot-dip galvanizing steels.
