Chemistry of Steelmaking by Basic Oxygen .

Chemistry of Steelmaking by Basic Oxygen Furnace. During the steelmaking process by basic oxygen furnace (BOF), impurities in hot metal such as carbon (C), Silicon (Si), manganese (Mn), phosphorus (P) etc. are removed by oxidation for the production of liquid steel. Oxidation is carried out with high purity oxygen gas which is blown in the BOF.

Ferro Silicon - Steelmaking Material | Wanhua Metal

Ferrosilicon is used frequently in steel making. This is because silicon reacts with oxidation to produce SiO2. Therefore, ferrosilicon can be used as a deoxidizer. At the same time, when SiO2 is formed, a large amount of heat is released. This is beneficial to increase the temperature of the molten steel. Ferro silicon specification
