METHOD OF LINING CATHODE DEVICE OF ELECTROLYSIS CELL Russian patent published in 2017 - IPC C25C3/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of lining a cathode device of an electrolyser for production of primary aluminium by electrolysis. Method involves loading a heat-insulating layer, consisting of non-graphitised carbon, in casing of cathode device, formation of a refractory layer of filling powder of aluminosilicate composition and compaction thereof by vibration compaction, installation of hearth and on-board units with further sealing of joints between them with cold-ramming paste. Heat-insulating material, consisting of non-graphitised carbon, is placed in cluster modules and is placed in base of electrolysis cell in at least one layer, and seams between them are sprinkled with non-graphitised carbon.

EFFECT: reduced dust release during installation of cathode device, reduced power consumption during operation of electrolysis cell owing to optimisation of thermophysical properties of lining materials of base of electrolysis cell.
