DESCRIPTION
Ferrosilicon is an essential deoxidizer in steelmaking industry. In torch steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel, improve the permeability of steel, and reduce the hysteresis loss of transformer steel. The content of silicon is 0.15%-0.35% in general steel, 0.40%-1.75% in structural steel, 0.30%-1.80% in tool steel, 0.40%-2.80% in spring steel, 3.40%-4.00% in stainless acid-resistant steel, 1.00%-3.00% in heat-resistant steel. Silicon steel contains 2% ~ 3% silicon or higher.
