Product Introduction
Used as a deoxidizer and alloying agent in the steelmaking industry. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out in the later stage of steelmaking. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer for steelmaking for precipitation and diffusion. deoxidation. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel. In the steelmaking industry, ferrosilicon is used to emit a lot of heat at high temperatures and is often used as a heat generating agent for steel ingot caps. To improve the quality and recovery rate of steel ingots. Used as inoculant and spheroidizing agent in the cast iron industry. Used as a reducing agent in the production of ferroalloys in other aspects. The ground or atomized ferrosilicon powder can be used as the suspended phase in the mineral processing industry. It can be used as a coating for welding rods in welding rod manufacturing. High-silicon ferrosilicon can be used to make products such as silicone in the chemical industry.
Product Usage
Wholesale ferrosilicon can be used in the following situations:
    1. Used as a deoxidizer and alloying agent in the steelmaking industry.
    2. Used as an inoculant and spheroidizing agent in the cast iron industry.
    3. Used as a reducing agent in the production of ferroalloys.
