Test on 3N Aluminum Production by Molten Salt Electrolysis

在常规铝电解槽上,通过采用高品质的原材辅料、优化工艺技术条件和精细化操作管理,进行熔盐电解生产3N精铝试验,并对试验存在的问题进行了探讨。试验结果表明,铝液中各杂质元素含量都有不同程度的下降,铝液达到了3N精铝的标准,说明采用熔盐电解法生产3N精铝是可行的。采用熔盐电解法生产3N精铝,生产成本较常规方法大幅降低。

In the conventional aluminum electrolytic cell,the production of 3N refined aluminum by molten salt electrolysis was carried out by using high-quality raw material and auxiliary materials,optimizing technological conditions and fine operation management,and the problems existing in the experiment were discussed.and problems in the test were discussed.The results show that the content of impurity elements in the aluminum solution decreases in varied degrees,and the quality of the aluminum solution reaches the standard of 3N aluminum,which indicates that it is feasible to produce 3N refined aluminum by Molten Salt electrolysis.The cost of 3N Aluminum production by molten salt electrolysis is reduced substantially compared with conventional method.
