Electric Arc Furnace

Electric Arc Furnace Electric Arc Furnace means an extremely hot enclosed space, where heat is produced by means of electrical arcing for melting certain metals such as scrap steel without changing electro-chemical properties of the metal. Here, an electric arc is produced between the electrodes. This electric arc is used for melting the metal. The…
