    Electric arc furnace (EAF) steel making technology is more than hundred years old. Though De Laval had patented an electric furnace for the melting and refining of iron in 1892 and Heroult had demonstrated electric arc melting of ferro alloys between 1888 and 1892, the first industrial EAF for steel making only came into operation in 1900.

    1. Charging with a mixture of metal and lime.. 2. Melting the metal and scrap using electric arcs from the graphite electrodes. After this some more lime is added to clear out the oxides in the next step.. 3. Blowing with oxygen to oxidise elements such as carbon, silicon and manganese in the scrap metal. As in the BOS furnace, carbon monoxide escapes as a gas.

    The use of EAFs has expanded and now accounts for nearly 2/3 of steel production in the United States. The EAF is different from the blast furnace as it produces steel by using an electrical current to melt scrap steel and/or direct reduced iron. The EAF uses scrap steel and electricity to produce molten steel.

  • AISI | Electric Arc Furnace Steelmaking

    The number of charge buckets of scrap required to produce a heat of steel is dependent primarily on the volume of the furnace and the scrap density. Most modern furnaces are designed to operate with a minimum of back-charges. This is advantageous because charging is a dead-time where the furnace does not have power on and therefore is not melting.
