An electric arc furnace (EAF) is a furnace that heats 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. Arc furnaces used in research laboratories and by ...
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.
An electric arc between two nails. An arc flash is the light and heat produced as part of an arc fault (sometimes referred to as an electrical flashover), a type of electrical explosion or discharge that results from a connection through air to ground or another voltage phase in an electrical system.

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 ...
The explosion is under investigation by the Holliston Police and Fire departments, as well as Eversource. Norman Miller can be reached at 508-626-3823 or nmiller@wickedlocal.com.
A submerge-arc furnace's shell or casing is fabricated from steel. The lower part is lined with hard blocks of strongly calcined carbon, and the upper part with firebrick. The floor and lower section of the furnace are water-cooled. Three electrodes are placed at the angles of an equilateral triangle with rounded corners.
An electron-beam furnace (EB furnace) is a type of vacuum furnace employing high-energy electron beam in vacuum as the means for delivery of heat to the material being melted. It is one of the electron-beam technologies .
