Graphite electrodes in accordance with its specifications and the level of quality indicators, can be used in electric arc furnaces, furnace, the furnace resistance. Graphite electrodes used mainly for electric furnace steelmaking, and can also be used for industrial silicon, phosphorus, quartz glass, corundum and other industrial production. EAF is used to the graphite electrode into the heater current, a powerful current of the bottom electrode gas produced by arc discharge, Meanwhile emit a large amount of heat for smelting. Now I plant the graphite electrode production specifications are : Φ500, Φ450, Φ400, Φ350. Φ300 Φ250, Φ200 other varieties, but also according to the user's specifications require production of different products. Graphite electrode - ordinary functional graphite electrodes, graphite electrode impregnation, high-power graphite electrodes, UHP graphite electrodes. Physical and chemical indicators
