Ferrosilicon alloy is a deoxidizer used in steelmaking production. It improves the shape of inclusions and reduces the content of gas elements in molten steel. It is an effective new technology to improve steel quality, reduce costs, and save aluminum. It is especially suitable for the deoxidation requirements of continuous casting molten steel. Practice has proved that it 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. The production of silicon-aluminum ferroalloy can be divided into the following three stages 1. Generation of silicon carbide At lower temperatures, SiO2 reacts with carbon to produce silicon carbide, 2. Generation of aluminum oxide carbides and carbides In the temperature range of 1600~2000�ºC, carbon reacts with aluminum oxide to form aluminum oxide and silicon carbide; 3. Intermediate compounds such as carbides decompose silicon-aluminum-iron to form. At a higher temperature, aluminum oxide, silicon carbide, aluminum carbide and silicon dioxide react to obtain silicon-aluminum; only high-quality silicon-aluminum ferroalloy can produce high-quality silicon-aluminum iron blocks. When purchasing silicon-aluminum iron balls, you need to pay attention to Its quality, the quality of silicon aluminum iron ball has a direct impact on its application.
