Electric arc furnaces are a refractory brick-lined U-shaped vertical vessel in which scrap steel, hot metal and sponge iron are melted by an electric arc. Electric Arc Furnaces (EAF) are used to produce carbon steels and alloy steels by using high-power electric arcs formed between a cathode and one (for DC) or three (for AC) anodes. An electric current is passed through the electrodes to form an arc. The heat generated by this arc melts the scrap.
Nowadays, Scrap is by far the most important resource, accounting for about 80% of all electric arc furnace metal feedstock.
