| 摘要 |
The invention relates to an electrolytic cell for obtaining aluminium, including a pot shell, at least one cathode block arranged at least partially in the pot shell, at least one anode suspended above the cell and dipping into the upper portion of the electrolytic cell, and an insulation at least partially covering the internal surface of the pot shell and located between the cathode block and the pot shell, the pot shell and the elements that it contains delimiting a crucible intended to receive an electrolytic bath in contact with the cathode block, characterised in that the insulation is at least partially made of carbon-based blocks having a heat conductivity lower than 1 W/m/K.
