Rendering of a ladle furnace, a variation of the electric arc furnace used for keeping molten steel hot. For steelmaking, direct current (DC) arc furnaces are used, with a single electrode in the roof and the current return through a conductive bottom lining or conductive pins in the base. The advantage of DC is lower electrode consumption per ...
Birlec Ltd. was an English manufacturer of industrial electric furnaces. Birlec was founded in 1927, as the Birmingham Electric Furnace Company, establishing a factory at Tyburn Road, Erdington, Birmingham. In 1954, Birlec's owner the Mond Nickel Company sold the company to Associated Electrical Industries. [1]
The Submerged-arc furnace for phosphorus production is a particular sub-type of electric arc furnace used to produce phosphorus and other products. Submerged arc furnaces are mainly used for the production of ferroalloys. The nomenclature submerged means that the furnace's electrodes are buried deep in the furnace burden.
The indirect arc electric furnace of the Stassano type, in its final configuration, is made from a cast iron cylindrical structure lined internally with refractory bricks. The structure is divided in two separate sections: an upper section where the electrodes are placed, and a lower crucible where the burden is loaded and fused into steel.
Paul (Louis-Toussaint) Héroult (10 April 1863 – 9 May 1914) was a French scientist. He was one of the inventors of the Hall-Héroult process for smelting aluminium, and developed the first successful commercial electric arc furnace. [1] He lived in Thury-Harcourt, Normandy.
An electric arc between two nails. An electric arc (or arc discharge) is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma, which may produce visible light. An arc discharge is initiated either by thermionic emission or by field ...

Electron-beam furnaces are used for production and refining of high-purity metals (especially titanium, vanadium, tantalum, niobium, hafnium, etc.) and some exotic alloys. [1] The EB furnaces use a hot cathode for production of electrons and high voltage for accelerating them towards the target to be melted.
