摘要： A graphite electrode for an electrothermic reduction furnace is formed from anode grade coke and graphitized at a graphitization temperature below 2700° C. The resulting electrode is particularly suited for carbothermal reduction of alumina. It has an iron content of about 0.05% by weight, a specific electrical resistivity of above 5 μOhm·m, and a thermal conductivity of less than 150 W/m·K. The graphite electrode is manufactured by first mixing calcined anode coke with a coal-tar pitch binder, and a green electrode is formed from the mixture at a temperature close to the softening point of the pitch binder. The green electrode is then baked to carbonize the pitch binder to solid coke. The resultant carbonized electrode, after further optional processing is then graphitized at a temperature below 2700° C. for a time sufficient to cause the carbon atoms in the carbonized electrode to organize into the crystalline structure of graphite.

摘要： A graphite electrode for an electrothermic reduction furnace in which aluminum is produced by carbothermic reduction of alumina is rendered substantially gas-impermeable. The graphite electrode is consumed during furnace operation and electrode columns connected by graphite pins are fed continuously fed in from the top into the furnace. The coating of the electrode withstands a temperature of up to 300° C. and more over a period of several hours without oxidation. Since the coating enters the furnace compartment at least partially, it is configured so that it will not contaminate the hot melt. That is, the chemistry of the coating materials is similar to 1o the ingredients of the overall reaction or, at a minimum, the amount of foreign elements is very low. The coating is provided so that it does not increase the electrical contact resistance at the connection between the electrode columns and the electrode holding clamps. Where the electrode inlet area is cooled by water, the coating is insoluble in water.
