Steelmaking - Wikipedia

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: Fe2O3(s) + 3 CO(g) → 2 Fe(s) + 3 CO2(g)

Direct reduced iron - Wikipedia

Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).

How steel is produced from iron ore and carbon studied ...

Transcript. NARRATOR: An important use of iron ore is the production of steel. Iron alone is too soft to be of structural value, but, when combined with less than 2 percent carbon at a very high temperature, it creates the alloy steel. Steel is a strong, hard material with valuable mechanical properties. It is the most widely used structural ...

Production - voestalpine Stahl Donawitz GmbH

To make iron from the ore, it is reduced and melted in a blast furnace with coke at over 1300°C. The resulting pig iron contains more than 2% carbon and cannot be used for products in this form. It is only through the LD process that the pig iron is converted into steel by blowing it with pure oxygen.
