Abstract
The invention relates to a special carbon and graphite composite structure cathode carbon block of an aluminum electrolytic cell. The cathode carbon block cancels the original cathode carbon block steel bar bank, the steel bar grooves on the bottom of the cathode carbon block along the length direction of the cathode carbon block and the cathode steel bars in the grooves; the end or angle place of the graphite electrode is provided with a conductive metal connection part; a voltage-regulating carbon layer using carbon and graphite material and TiB2/C material as main materials is constructed on the upper part and outer surface of the graphite electrode part; and the operating conditions of the aluminum electrolytic cell are combined with the Ohm's Law to perform function optimization and combination design to two parts with different resistance values so as to construct the special carbon and graphite composite structure cathode carbon block used in the cathode conductive structure of the aluminum electrolytic cell. The invention is characterized by high conduction efficiency, low resistance value, electrolytic corrosion resistance, low heat stress, less heat loss, easy realization of heat balance, low comprehensive cost and the like and lays the technical and economic foundation of the energy saving design of the electrolytic cell.
