The Latest Progress and Prospect of Special Metallurgical Products,Technology and Equipment in China
The high-end equipment industries in the fields of aerospace,energy,petrochemical,shipbuilding,rail trans-portation,new energy vehicles,energy conservation and environmental protection,and electronic information have devel-oped strongly,putting forward higher requirements for the quality and performance of special steel and special alloy materi-als,and the demand has surged.Therefore,in recent ten years,China's special metallurgy industry has been rapidly de-velopment.This paper first analyzes and summarizes the new requirements of ultra-high strength steel,supper alloy,cor-rosion resistant alloy,heat resistant steel,special stainless steel,high performance bearing steel,tool and die steel and precision alloy for the above-mentioned high-end equipment manufacturing.Secondly,the development status and trend of traditional special metallurgical processes and several new special metallurgical processes are analyzed.It is emphasized that the combination with basic oxygen furnace/electric arc furnace steelmaking process can provide high clean consumable electrode for electroslag remelting and vacuum arc remelting,and can also provide pure raw material for vacuum induction furnace.The short process of the electroslag remelting with continuous casting billet as the consumable electrode can sig-nificantly improve the production efficiency and reduce the production cost.At the same time,the duplex process of high nitrogen stainless steel smelting and the process flow of powder metallurgy and spray forming of tool and die steel are also briefly introduced.Third,China's special metallurgical industry development status,as well as the progress of new tech-nology and new equipment have been summarized.Finally,suggestions and prospects for the technical development of spe-cial metallurgy in China in the next ten years are put forward.
