Aluminum electrolytic cell lining structure

The utility model relates to the field of nonferrous metallurgy, and discloses an aluminum electrolytic cell lining structure. A bottom heat-insulation layer, a bottom seepage-proofing layer (3) consisting of dry-type seepage-proofing materials and a cathode block (2) are sequentially arranged at a lining bottom, a side heat-insulation layer is arranged at a lining side, a bottom side seepage-proofing layer (6) consisting of dry-type seepage-proofing materials is arranged between the lining bottom and the lining side on two sides of an aluminum reduction cell, a cathode seepage-proofing layer (10) is disposed between the lining side and the cathode block, and the side heat-insulation layer consists of a carbon block layer (1) and a ceramic fiber board layer (7) from inside to outside. The aluminum electrolytic cell lining structure can be applicable to heat balance conditions of low-voltage electrolytic aluminum production, meets the requirement of controlling heat balance on the condition of low-voltage adju
