DESCRIPTION
FerroSilicon Alloy 72 is a type of ferroalloy that is made up of approximately 72% silicon and 28% iron, with trace amounts of other elements such as aluminum, calcium, and carbon. It is a widely used additive in the steelmaking industry and is commonly used as a deoxidizer and alloying agent.
In steelmaking, FerroSilicon Alloy 72 is added to molten steel to improve its properties, such as strength, hardness, and resistance to corrosion. It can also help to reduce the amount of impurities in the steel, such as sulfur and oxygen, which can have negative effects on the final product.
FerroSilicon Alloy 72 can also be used in the production of other ferroalloys, such as ferromanganese and ferrochrome, as a reducing agent. It is also used in the manufacturing of cast iron, as an inoculant and nodularizer, to improve the mechanical properties of the final product.
The exact composition of FerroSilicon Alloy 72 can vary depending on the specific application, but it is typically produced by reducing quartz (silicon dioxide) with coke or coal in a submerged arc furnace. The resulting silicon and iron are then mixed in specific ratios to produce the desired grade of FerroSilicon Alloy.
