Ferro silicon is a gray color ferroalloy product which is made of iron and silicon. Different content of Si, Fe, Al, etc in Ferro silicon, different grade of ferro silicon, the most widely used is 75% ferro silicon and 72% ferro silicon . As we know that in the steelmaking industry, about 3-5 kg of 75% ferro silicon is consumed for every 1 ton of steel produced. Common particle sizes of ferro silicon are 0-3mm, 10-60mm, 10-100mm, etc. We are manufacturers of ferro silicon and can be customized according to user requirements.
The raw materials of ferrosilicon are coke, steel scrap, silica. Smelted in an electric furnace. In the process of steelmaking, silicon reacts with oxidation to produce SiO2, so ferro silicon can be used as a deoxidizer. Meanwhile when SiO2 is formed, a large amount of heat is released, it is beneficial to increase the temperature of the molten steel.
