改革开放以来,我国电解铝工业取得了飞速的发展。特别是20世纪的最后10年,我国铝产量从1990年的80多万吨增加到1999年的270多万吨,提高了约2.5倍。装备和技术水平也随着产量的增长获得了同步的发展。预焙电解槽从无到有,从小到大;大型预焙槽的操作和控制系统以及一系列 Since the reform and opening up, China’s electrolytic aluminum industry has achieved rapid development. In the last 10 years of the 20th century in particular, China’s aluminum production increased from about 800,000 tons in 1990 to about 2.7 million tons in 1999, an increase of about 2.5 times. The level of equipment and technology has also been synchronized with the growth of output. Prebaked cells from scratch, from small to large; large pre-baked cell operation and control system and a series of
