1989年日本由苏联进口海绵钛514t,比1988年的215t增加一倍多。此外还从苏联进口钛铁、钛硅铁1079t。苏联的钛冶炼方法与日本大阪钛公司、东邦钛公司相同,都是采用镁还原法,产品质量也与日本产品相近,而价格比日本稍低。质量相同的海绵钛,1989年12月由苏联购买的到岸价格为119万日元/t,日本产品则为130万日元/t。 日本进口海绵钛大部份用作生产高强度钢等材料的添加剂,钛材加工厂购入一部分海绵钛主要作为试验用料。新日铁(1989年用钛铁近3000t,预
In 1989, Japan imported 514 tons of sponge titanium from the Soviet Union, more than double the 215 tons in 1988. In addition, imports from the Soviet Union ilmenite, titanium ferrosilicon 1079t. The method of titanium smelting in the Soviet Union is the same as that of Japan Osaka Titanium Co., Ltd. and Toho Co., all using magnesium reduction method. The quality of products is also similar to that of Japanese products, while the price is slightly lower than that of Japan. Titanium sponge of the same quality, the CIF value purchased by the Soviet Union in December 1989 was ¥ 1,190,000 / t and that for Japanese products was ¥ 1,300,000 / t. Most of Japan’s imports of titanium sponge for the production of high strength steel and other additives, titanium processing plant purchased part of the main titanium sponge as a test material. Nippon Steel (1989 with nearly 3,000 tons of titanium, pre-order
