改革开放以来,我国铝工业发展迅速,1998年电解铝产量达到240万吨,已占世界总产量的12％,彻底改变了电解铝长期供不应求的局面。电解铝是高电耗行业,吨铝综合电耗1.6万千瓦·时左右,1998年全行业用电量380亿千瓦·时,电费支出达到制造成本的40％,远高于国外铝厂的负担水平。为借鉴发达国家经验, Since the reform and opening up, China’s aluminum industry has developed rapidly. In 1998, the output of electrolytic aluminum reached 2.4 million tons, accounting for 12% of the world’s total output, completely changing the long-term shortage of electrolytic aluminum. Electrolytic aluminum is a high electricity-consuming industry. The comprehensive electricity consumption per tonne of aluminum is about 16,000 kilowatt-hours. In 1998, the electricity consumption of the whole industry was 38,000,000,000 kilowatts. The electricity bill would reach 40% of the manufacturing cost, which is much higher than that of foreign aluminum plants Level. To learn from the experience of developed countries,
