Steel Dynamics, Inc. - Steelmaking Process

Because it uses fewer natural resources and less energy, the mini-mill steelmaking process is more cost-effective and environmentally friendly than the traditional integrated steelmaking method. In the mini-mill process, high-grade steel scrap is coined with pig iron, hot briquetted iron (HBI), and other metals and melted at a temperature of approximately 3,000 degrees …

Steps in the Modern Steelmaking Process

21/8/2020· Primary steelmaking has two methods: BOS (Basic Oxygen Furnace) and the more modern EAF (Electric Arc Furnace) methods. The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%.

To produce steel, facilities use one of two processes: the basic oxygen furnace (BOF…

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 …
