【Abstract】 A brief introduction is given to the worldwide aluminum industry in the 1990s with the emphasis on the 300KA reduction cell technologies represented by French Pechiney "AP-30". These technologies are recognized as the most advanced in the world. It has good technical indexes with an average current efficiency of 94. 9% and energy consumption of about 13000 kwh per ton aluminum. Both investment and cost are reduced remarkably.更多还原
