随着镁合金材料的不断发展以及汽车用铝镁合金材料的扩大使用,国内外市场对镁的需求日益增加。据统计,1985～1995年的10年间,世界市场镁的消费从23.1万吨上升到30.4万吨,我国镁的消费亦从0.8万吨增加到1.5万吨。 与国内外镁消费量急剧增长相对应的是,我国镁工业的发展也从80年代中期开始进入快车道,至80年代末,镁产量年平均增长率为13.5％。90年代以来,我国镁产量连年翻番,不但扭转了长期依赖进口的局面,而且成为重要的
With the continuous development of magnesium alloy materials and the expanded use of aluminum-magnesium alloy materials for automobiles, the demand for magnesium in domestic and overseas markets is increasing day by day. According to statistics, during the 10 years from 1985 to 1995, the consumption of magnesium in the world market increased from 231,000 tons to 304,000 tons. The consumption of magnesium in China also increased from 0.8 million tons to 15,000 tons. Corresponding to the rapid growth of magnesium consumption at home and abroad, the development of magnesium industry in our country started to enter the fast lane from the mid-1980s. By the late 1980s, the average annual growth rate of magnesium production was 13.5%. Since the 1990s, China’s magnesium production has doubled every year, not only reversed the situation of long-term dependence on imports, but also became important
