What are the characteristics of ferrosilicon powder?

Ferrosilicon powder is widely used as an alloying element in low-alloy structural steel, bearing steel, etc. At the same time, ferrosilicon powder is also used as a reducing agent. When the content of silicon element reaches more than 95%, it can also be used to manufacture single crystal silicon or configure non-ferrous silicon. Metal alloys.
The ferrosilicon powder rolled by ferrosilicon is heavier. After adding it, it can quickly enter the molten steel and undergo precipitation and deoxidation to increase the silicon content of the molten steel. The ferrosilicon powder rolled with high ferrosilicon is lighter, which is very conducive to diffusion deoxidation. Moreover, the higher the silicon content, the stronger the deoxidation effect. Therefore, ferrosilicon powder is generally rolled from high-grade ferrosilicon.
When ferrosilicon powder is first added, it has little effect on the heating time of the molding sand, but it has a significant impact on the heating temperature and the strength of the plastic sand after hardening. As the amount of ferrosilicon powder added increases, the heating temperature and intensity increase. The higher the silicon content in ferrosilicon, the finer the particle size, the less surface oxidation, and the greater its effect.
