FIELD: metallurgy.
SUBSTANCE: invention relates to the method of cathode pack manufacturing for the aluminium electrolyser. Method includes manufacturing of initial materials containing two grades of coke with different characteristics of volume change, formation of the cathode pack, carbonization, graphitization and cooling, during which in the same temperature range the first grade of coke has more higher shrinkage and/or expansion then the second grade of the coke. Cathode pack of the aluminium electrolyser is described.
EFFECT: increased service life of the cathode packs.
