The application of metallurgy low carbon ferro siliconferrosilicon fesi powder

1. Adding a certain amount of silicon to steel can effectively improve the strength, hardness and elasticity of steel. Therefore, when smelting structural steel, tool steel, spring steel, and silicon steel for transformers, ferrosilicon powder is also used as an alloying agent. . It is used as an inoculant and a nodularizing agent in the cast iron industry.

2. Adding a certain amount of ferrosilicon powder and metallurgical materials to cast iron can prevent the formation of carbides in iron and promote the precipitation and spheroidization of graphite. Therefore, in the production of ductile iron, ferrosilicon powder is an important inoculant (helping Precipitated graphite) and nodularizing agent.

3. Used as a reducing agent in the production of ferroalloys. Not only the chemical affinity between silicon and oxygen is very large, but also the carbon content of high-silicon ferrosilicon powder is very low. Therefore, high-silicon ferrosilicon powder (or siliceous alloy) is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry.

4. Use in other aspects. The ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry.

5. It can be used as a coating for welding rods in the welding rod manufacturing industry. High-silicon ferrosilicon powder can be used in the chemical industry to manufacture products such as silicone.

Unexpectedly, we often see that the welding rods used by the masters of electric welding doors and windows are also smelted by ferrosilicon powder. Many people have to sigh that ferrosilicon powder has many uses and wide applications!
