石墨电极

Graphite electrode, mainly petroleum coke, needle coke, coal tar pitch as binder, the calcined, ingredients, kneading, compression type, baking, graphite, machining and made the arc in electric arc furnace in the form of release energy for heating and melting of the charge of the conductor, according to its level of quality indicators can be divided into ordinary power, high power and high power.Graphite Electrode is mainly used for electric steelmaking and mining, and electric resistance heat furnace. Import current through the graphite electrodes in electric arc melting region, the melting temperature of about 2000 °C. In the graphite electrode products applicable to the common furnace and high-voltage high-power short-arc furnace.Specifications and indicators:General power graphite electrodes:1.
