Properties and uses of Ferrosilicon
Ferrosilicon is a widely used ferroalloy variety. It is silicon and iron in a certain proportion of ferrosilicon alloy, is an indispensable material for steelmaking. Ferrosilicon is the deoxygenation agent of steelmaking, is the alloy agent of silicon Steel, smelting spring steel, heat-resistant steels, but also to add a certain number of ferrosilicon as alloying agent. Production practice has proved that the oxygen in steel can significantly worsen the properties of steel and reduce the mechanical properties of steel. Therefore, deoxygenation must be necessary in the steelmaking process. Oxygen is present in steel in the ﹙FeO﹚ state of ferrous oxide. Silicon is an element with a strong ability to bind to oxygen. When Ferrosilicon is added to the steelmaking process, the following deoxygenation reaction occurs: 2FeO+Si=2Fe+SiO2 Silica ﹙SiO2﹚ is a product of deoxygenation, it is lighter than steel, floating steel liquid surface into the slag, thu...
