350KA双钢棒阴极电解槽技术研究与应用

电解铝企业生产中降低能耗、节约成本、提高生产效率,一直都是企业追求的目标,并以此为研究方向,开展各项生产工作。该文以科学的理论知识为基础结合生产中的实际经验,以350KA电解槽槽型结构和生产管理为研究重点,取得以下实验结果。依据350KA系列现生产中存在的问题,对槽型结构和母线实施改造,补偿电流的安装平衡槽周边磁场,稳定铝液的流动。槽型结构的改造使电解槽能量输入、支出达到动态平衡,槽温控制在适宜范围内,合理的槽型设计能有效抵消因内衬膨胀产生的推动力,减少槽体发生偏移和变形的机率。

It has always been the goal of electrolytic aluminum enterprises to reduce energy consumption,save costs and improve production efficiency,and take this as the research direction to carry out various production work.Based on scientific theoretical knowledge and practical experience in production,this paper focuses on the cell structure and production management of 350KA electrolytic cell,and obtains the following experimental results.According to the problems existing in the production of 350KA series,the groove structure and busbar are reformed,and the compensation current is installed to balance the magnetic field around the tank to stabilize the flow of molten aluminum.The transformation of the cell structure makes the energy input and expenditure of the electrolytic cell reach a dynamic balance,the cell temperature is controlled within a suitable range,and the reasonable design of the cell can effectively offset the driving force caused by the expansion of the lining and reduce the probability of deviation and deformation of the cell.
