| Abstract: |
| Existing form and reaction process of lithium salts were calculated by thermodynamic data. The influence of high lithium electrolyte on liquidus temperature and solubility of alumina was analyzed. Operation of 400 kA high lithium aluminum electrolytic cell was summarized from observingbaking start-up process, startup management, management in different stages of normal production. Stage reduction scheme of lithium was developed, and good effect was achieved. |
