中国钛的研究和发展

R & D of Titanium in China

介绍了中国钛工业发展的历史、钛的资源和钛的应用情况以及钛合金发展所取得的进展。中国钛工业经历了４０余年的研究和发展，目前产能已达到年产３６５０ｔ海绵钛和２８００ｔ钛加工材的生产能力，并建立了一个从海绵钛生产到钛锭熔炼、铸造、加工及钛设备制造的完整的钛工业体系。钛材已被广泛用於化学、宇航、航空等各个工业部门。中国已成长为世界上一个重要的钛工业国。同时还总结了中国钛工业发展的经验和教训；展望了中国钛工业的发展前途。

The history of China's Ti industry is described. Also discussed are China's Ti resource, progresses in the development and application of Ti alloys. After nearly 40 years of R & D experience, China's Ti industry has reached the production capacity of 3 650 tons of Ti sponge and 2 800 tons of Ti mill products. An integrated Ti industry system has been established in China, from Ti sponge production to Ti ingot melting, casting processing and equipment fabrication. The Ti materials have been widely used in chemical and aerospace industries as well as many other industrial sectors in China. Some of the experiences and lessons learned in the dovelopment of China's Ti industry are summarized in the paper. With the rapidly growing Chinese economy, the market for Ti is very attractive in the near term. The future outlook for China's Ti industry is also discussed.
