  • Developments in Electric Arc Furnace Steelmaking

    2016-11-21 · Electric Arc Furnace (EAF) Steelmaking technology became 100 hundred years old in the year 2000. Though De Laval had patented an electric fumace for melting and refining iron in 1892 and Heroult had demonstrated electric arc melting of ferro-alloys betvleen 1888 and 1892, the first industrial EAr steelmaking operations only came into

  • Types of Furnaces Melting process in a foundry

    When the furnace is sufficiently hot, pig and scrap iron are added. This melting process adds carbon and other elements producing different grades of iron and steel. Electric arc and induction methods are more efficient and have replaced cupola furnaces for most applications.

  • Electric Arc Furnace (EAF) [SubsTech]

    2012-5-31 · Dr. Dmitri Kopeliovich Electric Arc Furnace (EAF) is a steel making furnace, in which steel scrap is heated and melted by heat of electric arcs striking between the furnace electrodes and the metal bath. Two kinds of electric current may be used in Electric Arc Furnaces: direct (DC) and alternating (AC). Three-phase AC Electric Arc Furnaces with graphite electrodes are commonly used in steel

  • Steelmaking Process an overview ScienceDirect

    During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).

  • Steel Production American Iron and Steel Institute

    The first electric arc furnaces (EAFs) appeared in the late 19th Century. 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.
