1 前言约在1960年以前,霍尔-埃鲁特铝电解槽的能耗因充足廉价的电能随处可得而没有引起高度的重视。然而,现在大多数国家的铝工业都面临非常高的能源价格和电能短缺的问题。因而能源节约在经济上巳更为重要。然而,在过去电解槽的操作与管理中,能耗没有像电流效率那样受到人们的关注,尽管以前在这方面有许多问题,最近的数据却比较 1 INTRODUCTION About 1960, the energy consumption of the Hall-Elute aluminum reduction cell was not given enough attention due to the availability of sufficient cheap electricity. However, the aluminum industry in most countries now faces very high energy prices and electricity shortages. Energy conservation is therefore economically more important. However, in the past the operation and management of electrolytic cells, energy consumption did not receive the same attention as current efficiency, and although there have been many problems in this respect, recent data have been compared
