Ferro Silicon is an alloy made of iron and silicon, typically containing about 15% to 90% silicon, and is widely used in the steel and foundry industries. Its main function is as a deoxidizer, meaning it helps remove oxygen from molten steel, improving the strength and quality of the final product. It is also used as an inoculant in cast iron to control the microstructure and enhance mechanical properties. Ferro silicon plays an important role in improving hardness, durability, and resistance to corrosion in metals. Additionally, it is used in the production of silicon and as a reducing agent in various metallurgical processes. Due to its efficiency, cost-effectiveness, and strong performance in high-temperature applications, ferro silicon is considered an essential material in modern metal manufacturing.
