Products Description
ZhenAn Ferro Silicon Manufacturer
Ferro silicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made from coke, steel scraps, quartz (orsilica) as raw materials and smelted in an electric furnace. Since silicon and oxygen easily combine to form silica, ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, since SiO2 releases a large amount of heat when it is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing.
At the same time, Ferro Alloy can also be used as an alloying element additive and is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is often used as a reducing agent in ferroalloy production and chemical industry.

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 Ferro Silicon 65 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, Ferro Silicon 70 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 Ferro Silicon 70 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.

FAQ
Q：What is the purpose of ferro silicon?
A: Ferrosilicon is also used for manufacture of silicon, corrosion-resistant and high-temperature-resistant ferrous silicon alloys, and silicon steel for electromotors and transformer cores. In the manufacture of cast iron, ferrosilicon is used for inoculation of the iron to accelerate graphitization.
Q: What are the characteristics of Ferro Silicon Aluminum?
A：Ferro Silicon Aluminum is an odorless, crystalline solid metal. It is flammable and can react explosively with oxidizing materials. In the presence of moisture or water it may emit toxic and explosive fumes. It is used in magnesium processing.
Q: Is ferro silicon magnetic?
A: Ferrosilicon is known to possess good resistance to abrasion, good resistance to corrosion, high specific gravity, and high magnetism, which allows easy magnetic recovery.
