摘　　要：文章介绍了500 kA级大型铝电解槽的设计思路。母线设计采用了新型抗扰动稳流母线配置技术,解决了生产过程中当台槽不稳定时对上下游电解槽的扰动问题,并大幅度提高了端头槽的稳定性;内衬设计采用双平衡电解槽技术,采用区域保温,优化内衬结构,使电解槽形成了良好炉帮形状;槽壳采用整体焊接直角槽壳技术,明显改善了应力集中,槽壳变形小。并与测试和生产数据作比较,生产与设计形成了一个闭环,支撑了设计。This paper introduces the design idea of 500 kA large-scale aluminum electrolytic cell.Busbar design adopts a new type of anti-disturbance and current-stabilized bus configuration technology,which solves the disturbance problem of the upstream and downstream cells when the cell is unstable in the production process and greatly improves the stability of the end cell.The lining design adopts double-balance electrolytic cell technology,adopts regional thermal insulation,optimizes the lining structure,and makes the cell form a good furnace wall shape.The cell shell adopts the integral welding technology of a right-angle shell,which improves the stress concentration obviously and reduces the deformation of the shell.Compared with the test and production data,the production and design form a closed loop,which supports the design.
