Ferrosilicon is used in the steel industry as a deoxidizer and alloying agent. Ferrosilicon is used as an inoculant and spheroidizing agent in the foundry industry. Since steel making and foundry are fundamental heavy industries, it is necessary to understand the raw material additives used in heavy industries.
Introduction to ferrosilicon: Ferrosilicon is an iron alloy.
Ferrosilicon is an iron alloy consisting of silicon and iron. It is made by refining coke, iron scrap, and quartz (or silica) in an electric furnace and widely used in steel industry, foundry industry and other industrial production.
The common ones are 75 ferrosilicon, 72 ferrosilicon, 70 ferrosilicon and 65 ferrosilicon. Commonly used state of ferrosilicon lump: 0-3mm,1-3mm,3-10mm,10-50mm, 50-100mm. If customers need low aluminum ferrosilicon, we can also provide ferrosilicon with aluminum content of 0.5%max, 1.0%max, 1.5%max and 2.0%max.
Applications of ferrosilicon:
Used as a deoxidizer and alloying agent in the steel industry. To obtain steel with the appropriate chemical composition and ensure steel quality, deoxidation must be performed at the final stage of steelmaking. Silicon has a very high chemical affinity for oxygen. Therefore, ferrosilicon is a strong deoxidizer and can be used for precipitation and diffusion deoxidation in steelmaking processes. Adding a certain amount of silicon to steel can significantly improve the strength, hardness, and elasticity of the steel. Therefore, it is used in the smelting of structural steel, tool steel, spring steel, silicon steel for transformers, and is also used as an alloying agent. At the same time, improving the shape of inclusions and reducing the gas element content in molten steel are new technologies that are effective in improving steel quality, reducing costs, and saving hot metal. Particularly suitable for the deoxidation requirements of continuously cast liquid steel. It has been proven in practice that ferrosilicon not only meets the deoxidation requirements of steel manufacturing, but also has desulfurization performance.
