当使用电解法精炼铝时,阴极金属的质量则是评定生产工艺水平和经济效益的最重要标志之一。精铝电解槽多年运行的实践证实,阴极金属中主要杂质(铁、硅、铜)的含量与电解质和阳极合金的成分与水平、熔体温度、原铝的质量、电解槽的使用期限和结构、及其管理等因素有关。 When electrolysis is used to refine aluminum, the quality of the cathode metal is one of the most important criteria for assessing the level of the production process and the economic benefits. The practice of fine-pitch electrolytic cells for many years has confirmed that the content of major impurities (iron, silicon, copper) in the cathode metals is related to the composition and level of electrolytes and anode alloys, melt temperature, the quality of primary aluminum, pot life and structure , And its management and other factors.
