Electric arc furnace is use of electrode arc generated by high-temperature melting ore and metal, gas discharge arcing when the energy is concentrated, the arc temperature is 3000 degrees or more. For the melting metal, compared with other steel-making furnaces, EAF process is most flexibility, can effectively remove the sulfur, phosphorus and other impurities, temperature easy to control, small footprint, suitable for high-quality alloy steel smelting.

Electric arc furnace according to arc forms can be divided into " three-phase electric arc furnace", "consumable electrode arc furnace", "single-phase electric arc furnace" and "the resistance of electric arc furnace" and other types.
