Fesi 75 72 Ferrosilicion Alloy For Steel Making
Ferro silicon Description
Ferrosilicon is 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 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.
In addition, in the steelmaking industry, ferrosilicon powder is often used as a heating agent for steel ingot caps to improve the quality and recovery rate of steel ingots by taking advantage of the fact that ferrosilicon powder can release a large amount of heat when burned at high temperatures.
Ferro Silicon Application
1. Ferrosilicon is used as deoxidizer and alloy agent In the steelmaking industry.
2. Ferrosilicon is used as inoculant and spheroidizing agent in cast iron industry.
3. Ferrosilicon is used as reducing agent in alloy production.
