FIELD: metallurgy.
SUBSTANCE: invention relates to the cathode hearth, method of its manufacturing and use in electrolytic cell for aluminium manufacturing. The cathode hearth contains at least two cathode blocks and/or at least cathode block located at specified distance with creation of at least one clearance, material for blocks connection, being at least one pre-compacted plate out of expanded graphite, filling the clearance with possibility of connection to at least one cathode block. Method of manufacturing of the cathode hearth and its use in electrolytic cell for aluminium manufacturing are described.
EFFECT: increasing of the effective cathode surface of the aluminium electrolyser.
