摘　　要：槽电压降低的同时伴有电流效率损失是铝电解工艺调整中较常出现的情况,本文以铝电解企业的实际经济效益为考察对象,定量分析了直流电耗和电流效率的经济关系,建立了不强化电流和强化电流情况下与电流效率降低值相对应的节电费阈值、节能阈值和降槽电压阈值的计算方法,为企业选择最经济适宜的工艺技术条件提供支撑。In the process adjustment of aluminum reduction, the loss of current efficiency usually is accompanied by a reduced cell voltage. In this paper, the economic relationship between the DC power consumption and current efficiency was quantitatively analyzed based on the investigation of actual economic benefits of aluminum reduction enterprises. The methods for calculating the thresholds of saving electricity, saving power and decreasing cell volt- age, corresponding to the CE reduction value, were provided on the conditions of strengthening current or not. It provided support for the aluminum com- panies to choose the most appropriate technology economic conditions.
