日本大阪钛、东邦钛、昭和电工三家钛冶炼公司已开始着手共同研究海绵钛的新冶炼法“连续气相冶炼法”。从1992年起由年产能力1000t的试验工厂进行试验,定于1994年完成新冶炼技术的试验。 新冶炼法的研究费总额为10.35亿日元,通产省工业技术院提供50％的援助。连续气相法是将金属钛粒作为粒核装入反应器中部,原料TiCl_4及还 Japan’s Osaka Titanium, Toho State, Showa Denko three titanium smelting company has started to jointly study the new smelting titanium sponge method “continuous gas smelting.” From 1992 onwards by the annual production capacity of 1000t pilot plant test is scheduled to be completed in 1994, the new smelting technology test. The total amount of research fees for the new smelting law is 1.035 billion yen, and MIIT provides 50% assistance. Continuous gas phase method is the titanium metal particles into the reactor core as the core, the raw material TiCl_4 and also
