ZhenAn's ferrosilicon specifications are 3-8mm. Ferrosilicon particles are referred to as silicon particles, that is, ferrosilicon inoculant, which is an inoculant used in steelmaking, ironmaking, and casting. Huijin ferrosilicon has uniform particle size, no fine powder, stronger inoculation effect than ordinary ferrosilicon, and less tendency to produce slag. It reduces pinholes, improves the surface quality of cast pipes, and improves the pass rate of one-time delivery inspection.

Used as deoxidizer and alloying agent in steelmaking industry. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out in the final 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 the steel. Therefore, it is widely used in smelting structural steel (containing 0.40-1.75% silicon), tool steel (containing SiO.30-1.8%), and spring steel. (Containing SiO.40-2.8%) and silicon steel for transformers (containing 2.81-4.8% silicon), ferrosilicon is also used as an alloying agent.

At the same time, improving the shape of inclusions and reducing the content of gas elements in molten steel is an effective new technology to improve steel quality, reduce costs, and save iron. It is especially suitable for the deoxidation requirements of continuous casting molten steel. Practice has proved that ferrosilicon not only meets the deoxidation requirements of steelmaking, but also has desulfurization performance and has the advantages of large specific gravity and strong penetrating power.

Used as inoculant and spheroidizing agent in the cast iron industry. Cast iron is an important metal material in modern industry. It is cheaper than steel, easy to melt and smelt, has excellent casting properties and is much better than steel in earthquake resistance. In particular, the mechanical properties of ductile iron reach or are close to those of steel.

Adding a certain amount of ferrosilicon 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 is an important inoculant (helping to precipitate graphite) and spheroidizing agent. 

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