An electric arc furnace (EAF) is a metallurgical furnace that uses an electric arc to heat materials, mainly metallic ore or scrap metal from steel production. Metallurgical furnaces can be heated with different heat sources, but in an EAF, unlike an induction steel furnace, the charged metal is hea

Electric arc furnace is an electric furnace that uses the high temperature produced by electrode arc to melt ores and metals. The energy is very concentrated when the gas discharge forms the arc, and the temperature of the arc area is above 3000 ℃. For metal smelting, the electric arc furnace is more flexible than other steelmaking furnaces, which can effectively remove sulfur, phosphorus and other impurities. The furnace temperature is easy to control, and the equipment occupies a small area, which is suitable for smelting high-quality alloy steel.
