Manufacture And Use

When making steel, ferrosilicon needs to be quickly redundant in the molten steel to carry out chemical reactions. Some ferrosilicon blocks are difficult to solve. Due to the shape of the ferrosilicon blocks, they cannot quickly dissolve in the molten steel and react quickly. Therefore, at this time, it is necessary to reduce the shape of ferrosilicon, and ferrosilicon powder is a very ideal shape.

The production process of ferrosilicon powder is not complicated. It comes from the natural blocks of ferrosilicon that are ground into powder by high-precision grinding equipment. The ferrosilicon powder can be quickly dissolved in molten steel to achieve rapid deoxidation and rapid reaction. Features of the small occupied area.

Applications

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

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

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

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

Use in other ways. Ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry.

In the welding rod manufacturing industry, it can be used as a coating for welding rods. High silicon ferrosilicon powder can be used in the chemical industry to manufacture silicone and other products.
