FeSi is a kind of alloy which can be used as deoxidizer ,Inoculant and Nodulizer. It contains about 1% to 2% of Ca and Al.It makes improvement in the metallic structure and granulation in the molding of alloy and non-alloy cast irons, restoration of other Ferro alloys, and especially in the structure of nouvelle alloy steel. We make different grades ferro silicons .
Chemical Physical Composition
Application and Features
1. Silicon and oxygen are easy to react , ferrosilicon is often used as a deoxidizer in steel making, at the same time, a large amount of heat is released during the formation of SiO2, which can increase the temperature of molten steel while deoxidizing.
2. Adding a certain amount of silicon to the molten steel ,can significantly improve the strength, hardness and elasticity of the steel, ferrosilicon is also used as alloying agent.
3. Ferrosilicon can be used as an inoculant for ductile iron in iron casting, can preventing carbide formation , promoting the precipitation and spheroidization of graphite, improveing the performance of iron.
4. In other areas, The finely or atomized treated ferrosilicon powder can be used as a suspension phase in the beneficiation industry. It can be used as a coating for welding rods in the electrode manufacturing industry. High silicon ferrosilicon can be used in the chemical industry such as making silicone.
