Ferrosilicon powder is a versatile material with a wide range of industrial applications. It is commonly used as an alloying element in low-alloy structural and bearing steel, among other applications. In addition to being used as an alloying agent, ferrosilicon powder also serves as a reducing agent in various industrial processes. With a silicon content of more than 95%, it can also be used to produce single-crystal silicon or configure non-ferrous alloys.
The ferrosilicon powder used for rolling is heavier, and once added, it can quickly enter the molten steel for deposition and deoxidation, increasing the silicon content of the steel. The use of high-silicon iron powder for rolling is lighter, which is very conducive to diffusion and deoxidation. In addition, the deoxidation efficiency increases with the increase in silicon content, making ferrosilicon powder an ideal choice for production.
When ferrosilicon powder is first added to the molding sand, its effect on the heating time is minimal. However, it significantly affects the heating temperature and strength of the plastic mixture after solidification. With the increase in the amount of ferrosilicon powder, the heating temperature and strength also increase. It is also important to note that the finer the particle size of the ferrosilicon, the less the oxidation of the surface and the stronger its effect.
