| Abstract: |
| The cathode carbon blocks installed in the Hall-Heroult cell bottom are subject to the environment of temperature gradient and concentration gradient of electrolyte and metals. Deformations may arise from the action of various forces and thermal and chemical expansion. This will affect the cell life and normal operation in aluminium production. In this paper, the deformation of the cathode carbon blocks is calculated with considering sodium penetration by using the finite element method. The results show that the deformation of cathode carbon blocks in the upper surface is more serious than that in the bottom. When restricted at both ends, the cathode carbon blocks may curve upwards and exfoliations may occur. |
