Use Of Ferro Silicon In Steel Industry
The silicon content reaches 95%-99%. Pure silicon is often used to manufacture monocrystalline silicon or prepare non-ferrous metal alloys.
Silicon Ferro is widely used in the steel industry, casting industry, and other industries.
Silicon iron is an essential deoxidizer in the steelmaking industry. In steelmaking, Fesi Ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to steel can significantly improve the strength, hardness, and elasticity of steel, increase the magnetic permeability of steel, and reduce the hysteresis loss of transformer steel.
Generally, steel contains 0.15%-0.35% silicon, structural steel contains 0.40% to 1.75% silicon, tool steel contains 0.30% to 1.80% silicon, spring steel contains 0.40% to 2.80% silicon, stainless acid-resistant steel contains 3.40% to 4.00% silicon, heat-resistant steel contains 1.00% to 3.00% silicon, and silicon steel contains 2% to 3% or more silicon. In the steelmaking industry, about 3 to 5 kg of 75% Fe Silicon is consumed per ton of steel.
