17/8/2020· In the electric arc furnace (EAF), and the basic oxygen furnace (BOF) for producing steel, the major off gas is carbon monoxide (CO). If the CO can be cousted to CO{sub 2}, and the energy transferred to the metal, this reaction will reduce the energy consumed in the EAF and allow for more scrap melting in the BOF which would significantly lower the energy required to produce steel.

To produce steel, facilities use one of two processes: the …

Another steelmaking process widely used today is the electric furnace. The furnace charge is generally 100 percent scrap, and an electric arc is used as the heat source for the refining process. The electric furnace is generally not used for deep drawing steel or very light gauge steel because of its inability to reduce the residual element levels typically found in ferrous scrap to the low

Use of Metallized Raw Materials in Electric Furnace …

The paper discusses the use of a secondary smelting technology for reinforcing steel (rebar) production at Baku Steel Company, LLC, noting the feasibility of adding metallized pellets to the furnace charge consisting of scrap metal and other manufacturing waste products. The addition of such pellets enhances the process of melting the charge in an electric arc furnace (EAF). The process
