  2. Electric arc furnace - Wikipedia

    en.wikipedia.org/wiki/Electric_arc_furnace

    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 ...

  3. Arc flash - Wikipedia

    en.wikipedia.org/wiki/Arc_flash

    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.

    In September 2023 the UK Government agreed to pay Tata a £500 million subsidy in order for it to invest in an electric arc furnace. This was in a bid to cut emissions resulting from the carbon-intensity of the current blast furnaces. Trade unions worried that the increased autonomy of the electric arc furnace would lead to job losses.

  5. Exploding wire method - Wikipedia

    en.wikipedia.org/wiki/Exploding_Wire_Method

    The exploding wire method or EWM is a way to generate plasma that consists of sending a strong enough pulse of electric current through a thin wire of some electrically conductive material. The resistive heating vaporizes the wire, and an electric arc through that vapor creates an explosive shockwave .

    Recent major capital expenditures include a new, state-of-the-art Blast Furnace "C" that began operation in 2007 (followed shortly by an explosion and subsequent dismantling of Blast Furnace "B".) In 2011, Severstal Dearborn completed the construction of a continuous linked pickle line tandem cold mill (PLTCM) and a hot-dip galvanizing line (HDGL.)

  8. Electric arc - Wikipedia

    en.wikipedia.org/wiki/Electric_arc

    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 ...

  9. Submerged-arc furnace for phosphorus production - Wikipedia

    en.wikipedia.org/wiki/Submerged-arc_furnace_for...

    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.
