From ore to steel – ArcelorMittalA mixture of iron ore and coal is then heated in a blast furnace to produce molten iron, or pig iron, from which steel is made. ArcelorMittal has a diversified fleet of production facilities to make steel, both basic oxygen furnaces and electric arc furnaces.
A guide to the language of steel – ArcelorMittalA type of steel that generally has only a small quantity of elements other than carbon, silicon, manganese, sulphur and phosphorus, so it has no significant alloying element. Coal The primary fuel used by integrated iron and steel producers.
Coal Geology | Geoscience AustraliaMetallurgical (coking) coal is black coal that is suitable for making coke, which is used in the production of pig iron. These coals must also have low sulphur and phosphorus contents, and are relatively scarce and attract a higher price than thermal coals.
FACT SHEET Energy use in the steel industryThe BFBOF route produces steel predominantly using raw materials such as iron ore, coal, limestone and recycled steel. About 75% of steel is produced using the BFBOF route. First, iron ores are reduced to iron, also called hot metal or pig iron. Then the iron is converted to steel in the BOF.

Metallurgical Coal, Kentucky Geological Survey, University ...Because the ideal coal for making coke rarely occurs in a single bed, it is common practice to blend several coals together to achieve the quality parameters needed to make coke for steel. Coals from western Kentucky are typically not used for steel production (, met coal.
Coke: Carbonized coal used primarily in steel production.When burned, coke generated an intense amount of heat but produced very little smoke, qualities that made it an ideal fuel for use in producing iron and steal. During the 1880's, coke began to replace charcoal in the making of steel at foundries in the United States.
Air Pollution Aspects of the Iron and Steel IndustryTo supply its heat requirements, the steel industry depends upon three major natural fuels: coal, oil, and natural gas. Of these, coal is the most important, since it supplies more than 80 percent of the iron and steel industry's total annual heat and power requirements.
