    Ironmaking and steelmaking

    • Carbothermic reduction of iron ore (Hametite) in blast furnace is a well known process. Overall process is written as: • Ironore oxide mineral + gangue + Reducer (C) + flux + hot blast oxygen enriched air = Pig iron (liquid) + Slag (liquid) + waste gas (CO,CO2,N2) • Iron ore contains Fe2O3, along with gangue materials such as SiO2, Al2O3. read more

  • Steel Production American Iron and Steel Institute

    Steel Production American Iron and Steel Institute

    How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved ... read more

    A Look at the Process of Pelletizing Iron Ore for Steel

    Iron ore is essential to meeting the demands of the steel industry that continues to build the world around us. Pelletizing, or balling, carried out through either a disc pelletizer or rotary drum, is a key part of efficiently and sustainably producing steel from iron ore fines of varying sources. read more

  • How steel is made a summary of a Blast Furnace

    How steel is made a summary of a Blast Furnace

    To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is iron alloyed with carbon, usually less than 1%. The following text is taken from the Structural Manual For Ironworkers Manual V-Volume I. read more
