OverviewCarbon dioxide emissionsHistoryModern processesSee alsoExternal links

Steelmaking is estimated to be responsible for 7 to 9% of the global emissions of carbon dioxide. Making 1 ton of steel produces about 1.8 tons of carbon dioxide. The bulk of these emissions results from the industrial process in which coal is used as the source of carbon that removes oxygen from iron ore in the following chemical reaction, which occurs in a blast furnace

Manufacture of Steel Steel Manufacturing Process and Steps

Jun 06, · The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace.

BloomeryThe Role of Carbon in Iron and Steel ProductionBlast FurnacePuddling FurnaceBessemer ConverterThe oldest form of smelting iron from iron ore is through the use of a bloomery. A bloomery is a small structure typically made out of clay or a similar material in which iron ore is refined into iron. Iron ore and charcoal are added to the bloomery and heated up. Over time, the carbon from the charcoal will combine with the oxygen in the iron ore to create carbon monoxide.
