Electric arc furnace

An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc.Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundries for producing cast iron products) up to about 400-tonne units used for secondary steelmaking..

Crucibles, Refractories and Ceramics

INSURAL lining systems can be installed on site at the customer facility or off-site at a Foseco-approved furnace installation company. Furnace downtime during re-lining is minimal with installation of the INSURAL lining system typically completed within 3 days and with no refractory sintering or dry out process necessary.

Processes

Today, refractory materials are used in a wide variety of industrial sectors. These ceramic materials are products that are generally used under a high-temperature load of 1500 C [] for lining and delivery of thermotechnical facilities, such as blast furnaces or converters, as well as for transport devices in iron and steel, aluminum, cement and ceramic industries, incineration plants and

Electric arc furnace — Wikipedia Republished // WIKI 2

Electric arc furnace. Quite the same Wikipedia. Just better. In the 19th century, a number of men had employed an electric arc to melt iron.Sir Humphry Davy conducted an experimental demonstration in 1810; welding was investigated by Pepys in 1815; Pinchon attempted to create an electrothermic furnace in 1853; and, in 1878–79, Sir William Siemens took out patents for electric furnaces of the
