The invention relates to an inner lining structure of a
cathode molten pool for an aluminum
electrolytic cell, which eliminates a
steel bar groove at the bottom of a
cathode carbon block, a
cathode steel bar and ramming paste of a
steel bar and reduces the
voltage drop at the groove bottom; a cathode conductive line is arranged in a heat-preservation and anti-leakage layer at the bottom of the cathode carbon block, the cathode carbon block adopts a sectional
mesh point type connection conductive method, so that the vertical
current distribution of the aluminum
electrolytic cell is more uniform, and the horizontal current is reduced; cathode inner lining conductive carbon blocks are arranged in the furnace walls at the two opposite sides in a multidirectional and sectional arrangement manner, therefore, not only the conditions are created for the widening design of the aluminum
electrolytic cell and the diversification of the cathode structure, but also a possibility for implementing the diversified structure of the cross section of the cathode carbon block is provided, and the constructive cost of the electrolytic
cell is favorable for reduction; and the upper surface of the cathode inner lining adopts concave-convex design, or an aluminum liquid magnetic
cyclone adjusting block is constructed, therefore, the horizontal fluctuation between the aluminum liquid and the
electrolyte interface surface can be reduced, the effects of reducing the electrolytic polar distance and setting the
low voltage are achieved, and the purpose of reducing the
power consumption for electrolyticaluminum production is achieved.
