摘要
我国电解铝企业使用大量富含Li和K的氧化铝进行生产,Li、K富集显著地改变了电解质的某些理化性质,影响电解生产。本文论述了LiF、KF对电解质物相、初晶温度、电导率、密度、铝溶解损失、氧化铝溶解等理化性质以及对铝电解生产的影响,并针对Li、K富集对铝电解生产的影响,归纳了相关的生产技术措施。
Many electrolytic aluminum enterprises use a large number of alumina rich in Li and K for production.Li and K enrichment significantly change some physical and chemical properties of the electrolyte,affecting electrolysis production.This paper discussed the effects of LiF and KF on the physical and chemical properties of electrolyte phase,primary crystal temperature,conductivity,density,dissolution loss of aluminum and dissolution of alumina,as well as the influence on aluminum electrolysis production.In view of the influence of Li and K enrichment on aluminum electrolysis production,relevant production technical measures were summarized.
