The manufacture of steel by electric arc furnaces (EAF) is continuing to increase in usage in the United States with current production estimated to be over 63 million tons per year. The reduction of emissions from steel producers has been slow for two main reasons: the need to maintain or increase current production levels and the lack of
What are the Benefits of Using Electric Arc Furnace
May 21, 2015· The electrodes are lowered into the furnace and come into contact with the materials resulting in an electric arc between them. The materials are then melted by the arc causing a liquid bath. Electric arc furnace temperatures can be considerably high around 1800-2500°C, based on the melting point of the fused materials.
Arc Furnace Electrodes | Coidan Graphite
Why use graphite arc furnace electrodes? Graphite electrodes are primarily used in electric arc furnaces for the steel production process. Large electrical currents are passed through the low conductivity electrodes, the power causes electric arcs between the tips of the electrodes and across the liquid steel, the arc is white hot circa 5000ºC.
Electric Arc Furnace - High Temperature Furnace Camera
An Electric Arc Furnace (EAF) is used in steelmaking to heat charged material (scrap metal) by means of an electric arc. Furnace temperatures can reach 3200°F (1760°C). Electric Arc Furnaces consist of a water-cooled refractory lined vessel covered with a retractable lid, through which one or more graphite electrodes enter the furnace to

Characteristics of Electric Arc Furnace Steelmaking – Hani
Electric arc furnace steelmaking mainly uses arc heat, and the temperature in the arc action zone is as high as 4000 °C. The smelting process is generally divided into a melting period, an oxidation period and a reduction period. In the furnace, not only an oxidizing atmosphere but also a reducing atmosphere can be caused, so the efficiency of dephosphorization and desulfurization is high.
Electrical Arc Furnace : 7 Steps (with Pictures
An electric arc furnace is a type of furnace that heats up materials using a very high current. The rods (which are made of graphite for its semi-conductive properties) heat up and create a plasma that can be directed to melt metals. Although electrical arc furnaces (EAFs) are reliant on large amounts of electricity, it is fairly cheap and in
The Advantages And Disadvantages of Electric Furnaces
Jan 08, 2016· 4. In industry, electric arc furnaces are used in steel making from scrap metal. The energy used is much less than from primary steel making from ores. While blast furnaces must remain in operation for up to years at a time, electric arc furnaces can be turned on an off according to demand. The Disadvantages of Buying an Electric Furnace. 1.
