  • Electric arc furnace - Wikipedia

    An electric arc furnace ( EAF) is a furnace that heats charged material by means of an electric arc . Industrial arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking.

  • Electric Arc Furnace Design Operation and Working Principle

    The Second World War saw a steep increase in the use of these furnaces leading to the modern Electric Arc Furnace design operation and working principles. These improvements to the processing of scrap steel comprised of larger more efficient and higher capacity furnaces; a 100T furnace would process the scrap in about an hour, using a transformer of 60MVA capacity.
