= Electric arc furnace
An <electric arc furnace> supplies <heat> through an <electric arc> between electrodes and the charge or molten bath. In <steelmaking>, it melts and refines material that can include recycled <steel> and <direct reduced iron>. It provides a different heating route from the internal oxidation heat central to <basic oxygen steelmaking>.<Steel Production by the American Iron and Steel Institute>[Electric-arc furnace route and feedstocks]{ref}
The electrical input does not by itself determine the product's <chemical composition>. The charge, additives, <slag> and refining reactions must also be controlled. Similarly, the route's <carbon dioxide> emissions depend on how its electricity and metallic feed were produced; melting scrap and reducing fresh <iron ore> are different system boundaries.
