arc furnaceType of electric furnace in which heat is generated by an arc between carbon electrodes above the surface of the material (commonly a metal) being heated. William Siemens first demonstrated the arc furnace in 1879 at the Paris Exposition by melting iron in crucibles; horizontally placed carbon electrodes produced an electric arc above the container of metal. The first commercial arc furnace in the U.S. (1906) had a capacity of four tons (3.6 metric tons) and was equipped with two electrodes. Modern furnaces range in heat size from a few tons up to 400 tons (360 metric tons), and the arcs strike directly into the metal bath from vertically positioned, graphite electrodes to remelt scrap steel or refine briquettes of direct-reduced iron ore. arc furnace [′ärk ′fər·nəs] (metallurgy) A furnace used to heat materials by the energy from an electric arc.

| Each of the six ladles of steel was melted in a single, 95-ton electric arc furnace and then subsequently treated and kept hot in rotation in either the vacuum arc degassing unit or the similar vacuum oxygen decarburization unit," Marston said. SDK) has decided to increase its production of 30-inch- and 32-inch-diameter graphite electrodes from around 15,000 tons/year at present, to 25,000 tons/year by 2010, to meet growing demand from electric arc furnace (EAF) steelmakers. Electric Arc Furnace (EAF)--A steel-making furnace in which ferrous scrap can make up to 100 percent of the material melted. |
