Common Classification Of Ferrosilicon

Ferrosilicon is commonly classified by its silicon content, with typical grades including 75#, 72#, 65#, and 45% silicon. It can also be categorized by carbon content, such as low-carbon and ultra-low-carbon ferrosilicon for specialty applications, or by other alloying elements like low-titanium (high-purity) ferrosilicon for electrical steels. Additionally, it can be classified by its physical form into block, granular, or powdered types.

1. Low-Silicon Ferrosilicon: Used primarily for rough deoxidation of plain carbon steel (e.g., initial oxygen reduction before tapping from a converter), composition adjustment in cast iron casting (replenishing the iron base while adding a small amount of silicon), or as a raw material for smelting other ferroalloys (such as silicomanganese alloys). Suitable for low-cost production scenarios with low deoxidation requirements.
2. Medium-Silicon Ferrosilicon: Offers moderate deoxidation capacity, balances cost and performance, and requires strict control over impurity content.
3. High-Silicon Ferrosilicon: Offers strong deoxidation capacity, precise silicon content (fluctuation ≤ ±0.5%), and low levels of harmful impurities. 4. Ultra-high silicon ferrosilicon: Mainly used for the preparation of high-purity polysilicon in the semiconductor and photovoltaic fields (as a silicon source), or as an alloying raw material for special alloys for aerospace (such as titanium silicon alloy). It has strict purity requirements, is used in small quantities, but has high added value.
