摘　　要：电解质中微量元素的含量不同,导致电解质的性质发生很大变化,针对兰州分公司高Ca F2、Li F、KF含量的复杂电解质体系,通过调整技术条件、添加适合的保温料,重点控制好过热度,使电解质的溶解度和导电度基本趋于合理,确保了电解生产稳定进行,从而探索出了复杂电解质体系下低电压稳定生产的途径。The content of trace elements in the electrolyte is different,which leads to a great change in the properties of electrolytes. In this paper,the complex electrolyte system with high Ca F2,Li F and KF content in Lanzhou branch is controlled by adjusting the technical conditions and adding suitable heat preservation material,and the solubility and conductivity base of the electrolyte are controlled. This tends to be reasonable and ensures the stable production of electrolytic production,thus exploring the way of low voltage and stable production under complex electrolyte system.
