Casting Iron Steel Casting Use FeSi Ferro Silicon 75% 72%

Ferrosilicon is an alloy material whose main components are silicon and iron, with small amounts of carbon, manganese, phosphorus and sulfur, and whose functions are as follows:

 

1.Improve the hardness and wear resistance of steel: the element silicon in ferrosilicon can significantly improve the hardness and wear resistance of steel, while also being able to reduce the elastic modulus of steel, making it softer.

2. Deoxidizer: The carbon and silicon elements in ferrosilicon can react with the oxides in the steel and reduce to gases such as CO and SiO2, thus acting as a deoxidizer and reducing the generation of oxides in the steel.

3. Alloying elements: silicon in ferrosilicon is a common alloying element that can significantly improve the physical and chemical properties of steel, such as improving strength, toughness, corrosion resistance, etc.

4. Increase furnace temperature: The high heat generated by the combustion of ferrosilicon can increase the furnace temperature, which is conducive to the steelmaking process.

In short, ferrosilicon has a variety of roles in steel production and can effectively improve the properties and quality of steel, while contributing to the efficiency of steel production.

Ferrosilicon, as an important alloying material, has the following advantages in steel production:

1. Improving the properties of steel: Silicon in ferrosilicon is a common alloying element that can significantly improve the physical and chemical properties of steel, such as improving strength, toughness, and corrosion resistance.

2. Reduce the cost of raw materials: ferrosilicon can replace some iron and pure silicon, reducing the cost of raw materials.

3. Increase furnace temperature: The high heat generated by the combustion of ferrosilicon can increase the furnace temperature, which is conducive to the steelmaking process.

4. Deoxidizer: the carbon and silicon elements in ferrosilicon can be used with the oxygen in the steel
