The chemistry of steelmaking. The big picture.

Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as WebThe stages of blowing remove carbon by the combination of oxygen and carbon forming CO gas. 4 Cr (bath) + 3 O 2 → 2 Cr 2 O 3 (slag) Cr 2 O 3 (slag) + 3 C (bath) → 3 CO (gas) + 2 Cr (bath) To drive the reaction to the …
