Ferro silicon alloy made by electric furnace smelting is an important alloy product, mainly used in the steel metallurgical industry. The main raw materials are high-purity silicon metal and iron ore (usually iron ore, iron concentrate, etc.).Using an electric arc furnace or electric furnace, metallic silicon and iron ore are reacted at high temperature to produce an FeSi alloy containing a certain silicon content.

Silicon content:

The silicon content of Ferro silicon alloys usually ranges from 15% to 90%, and Ferro silicon alloys with different silicon contents have different applications in industry.

Stability:

It has good chemical stability and thermal stability, is not easily oxidized or melted, and is suitable for use under high temperature conditions.
