- Utilization of electric arc steel making has allowed many smaller producers to compete with the large mills. An electric arc furnace (EAF) melts scrap metal to produce a variety of steel products. Using scrap as the metal source is less costly than refining from ores, but the metal is of a lower quality due to impurities in the scrap. Over the years, methods have been developed to improve EAF metal quality and reduce the cost of production. As a result, an increasing share of total steel production is shifting to EAFs. By recent estimates, EAF production is growing at a rate of about 10% per year, and currently accounts for nearly one half of all US steel production (US Department of Energy and Electric Power Research Institute Project 2787-2, 1987). The subject of this report is Scrap Preheating, a new method of preheating scrap metal before it is charged into an EAF. In scrap preheating, a portion of the energy is supplied in a separate vessel, causing the EAF to use less energy, which shortens the heating time. The general effect is that the arc furnace can produce more steel in a given time at a reduced cost per ton of molten metal.
