What is the difference between ferrosilicon 75A and ferrosilicon 75B?
- Silicon content: Ferrosilicon 75A requires a higher silicon content and is more stable, suitable for occasions with higher product quality requirements.
- Carbon content: The carbon content of ferrosilicon 75A is significantly lower than that of ferrosilicon 75B, which makes it more suitable for smelting processes sensitive to carbon content.
- Impurity content: 75A more strict control of sulfur, phosphorus, manganese and other impurities.
- Density: The density of ferrosilicon 75A is slightly higher, the physical structure is denser, and the reaction performance is more stable.
- Appearance: 75A appearance is more uniform, less impurities inside the block material; 75B May be partially caked due to higher carbon content.
- Particle size: The particle size standard of ferrosilicon 75A is more stringent, suitable for special smelting needs.
3. Difference of use (What is the difference between ferrosilicon 75A and ferrosilicon 75B?)
- With its low carbon and low impurity content, ferrosilicon 75A is suitable for high-end smelting processes with strict requirements on steel quality, such as special steel, stainless steel, alloy steel production.
- Ferrosilicon 75B is suitable for general steel and cast iron production with a high carbon content, and the refining requirements are not high.
