Electric Arc Furnace (EAF): Industrial furnaces that use metal or non-metal electrodes to generate arc heating are called electric arc furnaces.
It‘s a furnace that smelts ores and metals using the high temperatures generated by electrode arcs.
When the gas discharge forms an arc, the energy is very concentrated, and the arc temperature is above 3000 °C.
Electric arc furnaces are more flexible for metal smelting than other steelmaking furnaces. It can effectively remove impurities such as sulfur and phosphorus.
The furnace temperature is easy to control, and the equipment occupies a small area. It is suitable for smelting high-quality alloy steel.
The electric arc furnace body is composed of a furnace cover, furnace door, tapping groove, and furnace body. The furnace bottom and furnace walls are constructed with basic or acid refractory materials.
The ton furnace capacity transformer can be divided into ordinary, high-power, and ultra-high-power electric arc furnaces.
EAF steelmaking uses graphite electrodes to feed electrical energy into the electric arc furnaces. The arc between the electrode tip and the charge is used as a heat source for steelmaking.
Electricity is the heat source of the electric furnace, which can adjust the atmosphere in the electric furnace, which is very beneficial to the smelting of steel with more easily oxidized elements.
Using the high-temperature flue gas of the electric furnace, the raw materials can be preheated through technology and equipment to achieve high efficiency, energy saving, environmental protection and high yield.
