配置在铝电解厂房中的大容量电解槽的缺点之一是小面不能经常加工,难于在阴极端壁形成保护性槽帮结壳。无侧部槽帮结壳,会导致阴极内衬加速破损,降低电解槽使用寿命,损失电流和使电解工艺技术经济指标变坏。长期以来,人们一直注意保护电解槽两个阴极端头的碳素内衬问题:即采用碳块高度高于槽膛深度的阴极结构(两个端头抬高),研制电解槽小面的加工机械,以及使用各种保护性材料提高电解槽侧部内衬稳定性的研究等。
One of the disadvantages of a large capacity cell configured in an aluminum electrolysis plant is that the facets can not be machined often and it is difficult to form a protective trough shell on the cathode end wall. Without the help of the side groove shell, will lead to accelerated degradation of the cathode lining, reducing the life of the cell, the loss of current and the economic and technical indicators of the deterioration of the electrolytic process. For a long time, people have been paying attention to the problem of protecting the carbon linings of the two cathode ends of the electrolytic cell. That is, the cathode structure (two ends raised) with a carbon block height higher than the depth of the groove is used to process the facets of the electrolytic cell Machinery, and the use of various protective materials to improve the stability of the lining of the side of the tank and so on.
