 Mainly in the petroleum coke, needle coke as raw material, coal tar pitch as binder, the burning, ingredients, kneading, compression type, firing, graphite, machined and made in the form of electric arc furnace in order to release the energy of the charge arc for heating and melting of the conductor, according to its level of quality indicators can be divided into ordinary power, high power and high power. 
 Graphite Electrodes including: 
 (1) General power graphite electrodes. Allows the use of current density is lower than 17A / cm 2 graphite electrodes, primarily used in steelmaking, refining silicon, phosphorus and other common power refining furnace. 
 (2) anti-oxidation coating graphite electrode. Surface coated with anti-oxidant protection layer (graphite electrodes anti-oxidants) and graphite electrodes. The formation of both conductive and high temperature oxidation protection layer, when the electrode to reduce steel consumption (19% to 50%), to extend the life of the electrode (22% -60%), lower electrode of the power consumption. Promote the use of this technology can bring this economic and social effects: 
 ① graphite electrode unit consumption of less certain to reduce production costs. For example, a steel mill, according to the cut-off level did not occur throughout the year LF refining furnace graphite electrodes 35 or so a week, 165 Refined processing furnace consumed, the use of graphite electrode anti-oxidation technology, the annual savings of 373 (153 t) electrodes, each electrode per ton of high-power computing RMB 16,900, save 2.5857 million yuan. 
 ② graphite electrodes are less energy consumption, saving power consumption of steel-making unit, saving the cost of production, energy saving! 
 ③ As the graphite electrode for fewer, less the operation of the workers on the amount of labor and risk factors, improve production efficiency. 
 ④ graphite electrode is a high consumption and high pollution products, energy saving environmental protection advocates in a few days, has a very important social significance. 
 This technology in the country is still in the research and development stage, some domestic manufacturers have begun production. In Japan and other developed countries have been more widely used. At present, there have been specially imported this antioxidant protective coating company. 
 (3) high-power graphite electrodes. Allows the use of current density of 18 ~ 25A / cm 2 graphite electrodes, mainly for high-power electric arc furnace steelmaking. 
 (4) ultra-high power graphite electrodes. Allows the use of current density greater than 25A / cm 2 graphite electrode. Mainly used in ultra-high power electric arc furnace steelmaking.
