An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc. Arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking. Arc furnaces used in research laboratories and by dentists m...
An electric furnace used to melt steel scrap or direct reduced iron.
(EAF or EF) An economical method of steelmaking that is energized by an electric arc flowing between two bottom electrodes. Furnace charges consist of purchased scrap.
Since the second World War, this has been the standard furnace for melting steel in large quantities. Typical Capacities are 80 to 120 Tonnes. They were generally used as direct replacements for Siemens Open Hearth Furnaces.
A furnace used normally for both scrap and DRI-based steel making. Once the furnace is Charged and covered, graphite electrodes are lowered through holes in the roof. The electric arc traveling between the electrodes and the metallic Charge creates intense heat, which melts the Scrap and DRI. Alloying elements can be added during this process, or l...
An economical method of steelmaking that is energized by an electric arc flowing between two bottom electrodes. Furnace charges consist of purchased scrap.
A stainless steel producing furnace where scrap generally makes up a high percentage of the charge. Heat is supplied from electricity that arcs from the electrodes to the metal bath. These furnaces may operate on AC or DC.
A steel furnace that uses an electric arc to generate heat. After melting the steel is commonly cast into blooms, slabs or billets.
A furnace that melts steel scrap using the heat generated by a high power electric arc. During the melting process, elements are added to achieve the correct chemistry and oxygen is blown into the furnace to purify the steel.
