Infographic: the Iron and Steel Manufacturing Process

04/06/2015  Steel is made primarily in a two-step process. In the primary steelmaking step, liquid iron is converted into steel by the basic oxygen furnace (BOF) process, or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.

The Steel Manufacturing Process - How is Steel Made?

10/04/2020  Blast furnace: The blast furnace process, also known as the basic oxygen process (BOP), combines raw iron ore with small amounts of steel scrap metal into a furnace. Then, pure oxygen is blown into the furnace, raising its temperature. Not only does the scrap metal melt into a liquid at this temperature, but the iron’s impurities are also oxidized, evaporating completely. Additionally, the high temperature reduces the carbon content down to its ideal ratio, resulting in liquid steel.

How iron is made - material, manufacture, making, history ...

Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon content and adding other elements such as manganese and nickel to give the steel

23.3: Metallurgy of Iron and Steel - Chemistry LibreTexts

25/08/2020  Steel. Much of the iron produced is refined and converted into steel. Steel is made from iron by removing impurities and adding substances such as manganese, chromium, nickel, tungsten, molybdenum, and vanadium to produce alloys with properties that make the material suitable for specific uses. Most steels also contain small but definite percentages of carbon (0.04%–2.5%). However, a large part of the carbon contained in iron must be removed in the manufacture of steel
