电解铝厂的能源消耗以电能为主,一般占能源构成的90％以上,这就要求有一个较科学的电耗计算办法。目前各铝厂电能消耗的主要考核指标是直流电耗。诚然,直流电耗是铝电解生产过程中的一项重要技术经济指标,但它只能反映铝电解槽本身的平均电能利用情况,而不能全面反映一个铝厂(或一个车间)的电能利用情况(如:生产布局及生产组织是否合 Energy consumption of electrolytic aluminum plant to electricity-based, generally accounting for more than 90% of energy composition, which requires a more scientific method of calculating power consumption. At present, the main assessment indicators of each aluminum plant power consumption is DC power consumption. It is true that DC power consumption is an important technical and economic indicator in the production of aluminum electrolysis but it can only reflect the average power utilization of the aluminum reduction cell itself and can not fully reflect the power utilization of an aluminum plant (or a workshop) Such as: production layout and production organization is the same
