深入论述了铝电解工艺优化问题,认为中间下料预焙槽使用物理性能优良的砂状氧化铝,为铝电解工艺优化提供了优越条件。介绍了点式上料和线式下料的特性和装置,提出了上插槽点式下料的新方案。论述了铝电解过程的优化控制,特别是介绍了国内铝电解槽自适应控制技术的新进展。文中还介绍了铝电解槽阴极结构的优化和延长电解槽寿命等问题,认为槽壳为船形结构更为合理。
The aluminum electrolysis process optimization problem is discussed in depth. The use of sand-like alumina with excellent physical properties in the intermediate prebake prebake bath provides superior conditions for aluminum electrolysis process optimization. The characteristics and devices of point feeding and linear feeding were introduced, and a new scheme of point feeding on the slot was put forward. The optimal control of aluminum electrolysis process is discussed, especially the new progress of adaptive control technology of aluminum electrolytic cell in China. The paper also introduced the optimization of the cathode structure of the aluminum reduction cell and the problem of prolonging the life of the cell. It is more reasonable to think that the cell shell is a boat-shaped structure.
