Workers in smelters attempt to reach the optimal cell conditions during this period with minimal detrimental impact on the properties of the various materials [4] as soon as possible.
In some smelters LiF and MgF2 can be added to the electrolyte to modify the physico-chemical properties and improve the cell performance [24].
So, the temperature and AlF3 concentration of electrolyte [26] are very important factors for aluminum reduction cells.
The increase in the electrolyte temperature during the first days of cell operation is related to the lower content of the AlF3 in the electrolyte, and these parameters are considered very important factors in the cell current efficiency.
