Learn about the history, construction and operation of electric arc furnaces, which heat material by means of an electric arc. Find out how they are used for steelmaking, calcium carbide production and other applications.
Sep 29, 2023 · An electric arc furnace (EAF) uses electricity to generate a high-intensity electric arc. The arc forms between two electrodes, typically made of carbon or graphite. When high voltage is applied, it ionises the air between the electrodes, creating a conductive path. The electric arc produces extreme heat, reaching temperatures up to 3500°C.
