Applications of Graphite Electrodes
Electric arc furnace steelmaking is a major consumer of graphite electrodes. In China, electric‑arc furnace steel accounts for approximately 18% of total crude steel production, and graphite electrodes used in steelmaking comprise 70% to 80% of the country’s total graphite electrode consumption. In this process, current is passed through graphite electrodes into the furnace, and the high‑temperature heat generated by the electric arc between the electrode tips and the charge is utilized for smelting.
Production Characteristics of Graphite Electrodes
(1) Long production cycle. The production cycle for standard‑power graphite electrodes is approximately 45 days, while that for ultra‑high‑power graphite electrodes exceeds 70 days; moreover, the production of graphite electrode joints requiring multiple impregnation processes takes even longer. (2) High energy consumption. Producing 1 ton of standard‑power graphite electrodes requires roughly 6,000 kWh of electricity, several thousand cubic meters of coal gas or natural gas, and about 1 ton of metallurgical coke pellets and metallurgical coke fines.
