Particle Sizes Of Ferrosilicon

Ferrosilicon is a ferroalloy product composed mainly of the elements Si and Fe. Although it has a wide range of applications, steelmaking, and foundry industries are its primary users. The ferrosilicon used in steelmaking typically contains 72% to 75% Si, and low aluminum ferrosilicon and low titanium ferrosilicon are commonly used in the process.

Common Particle Sizes Of Ferrosilicon For Steelmaking

The typical particle size of ferrosilicon used in steelmaking is in block form, with a particle size requirement of 10mm to 60mm. Ferrosilicon larger than 50mm and smaller than 10mm should not exceed 5% of the total weight. Ton packages are required for packaging.

Common Particle Sizes Of Ferrosilicon For Casting

Ferrosilicon used in casting must have low sulfur and low nitrogen to reduce the tendency of white mouth and honeycomb holes in castings. The particle size of common ferrosilicon for casting is typically less than 100mm, with a silicon deviation of no more than 3% and a particle size of 30mm to 70mm. The quantity of less than 20mm x 20mm should not exceed 2% of the total quantity. The common 75% ferrosilicon grains for casting require Si to be between 74.5% and 80%, S < 0.02%, and P < 0.035.

Since the particle size requirements for ferrosilicon vary based on the process, each manufacturer needs to perform rigorous calculations to determine the required particle size when purchasing ferrosilicon. They must then inform the ferrosilicon manufacturer of the results to ensure the correct particle size of ferrosilicon products is purchased.
