EAF by means of arc melting scrap. Alternating current AC electric arc furnace has three moving graphite electrodes. Heating and melting of metal is enabled by radiant energy of the arc burning between the electrodes and metal, and the temperature in the arc zone reaches 4000 °C. The uniform burning of arc is regulated by means of moving of current-carrying electrodes transversely to the surface of the melt. It is possible to regulate the radiant energy by stretching and contracting the arc with two moving electrodes.
