METHOD OF ALUMINIUM ELECTROLYSER WITH SELF-BAKING ANODE START Russian patent published in 2017 - IPC C25C3/06 

FIELD: electricity.

SUBSTANCE: method includes the bottom firing, the molten electrolyte casting, the cell electrical connecting, voltage reducing in the cell to the operating voltage during the starting period, loading soda containing raw materials, fluoride salts and pouring of liquid aluminium. Reduced cell voltage to an operating one is carried out simultaneously with a decrease in the level of the electrolyte and increase in the aluminium level in the cell and the level of total aluminium and electrolyte in the electrolytic cell is maintained between 91 and 99% of the mine depth.

EFFECT: reduced duration and power consumption of the electrolyser start-up period.
