From ore processing to alloy design, the journey of iron through blast furnaces, direct reduction plants, electric arc furnaces, and continuous casting molds shapes the steel industry's strength, versatility, and sustainability.
The first step in the iron manufacturing process is the extraction of iron ore from the earth. This is done through open pit mines or underground mines, depending on the location and quality of the deposit. Iron ore is found in the form of oxides, mainly in the form of hematite (Fe2O3) and magnetite (Fe3O4).
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.
