冰晶石—氧化铝熔体电解炼铝法沿用至今已92年,始终未被其它炼铝法所取代,而且尽管资本主义国家受能源危机影响,但是铝的生产一直保持着高速度增长,年平均增长率超过9％。为了继续保持“竞争”能力,必须解决能量效率低、成本高的问题。近年来,国际 Cryolite - alumina melt electrolytic aluminum has been used for 92 years so far, and has never been replaced by other aluminum smelting methods, and although the capitalist countries are affected by the energy crisis, the production of aluminum has maintained a high growth rate. The annual average The growth rate is over 9%. In order to continue to maintain a “competitive” capacity, we must address the issue of low energy efficiency and high costs. In recent years, international
