Characteristic
The Ferro Silicon Alloy is using coke, steel chips and quartz (or silica) as raw materials, after high temperature reduction of 1500-1800 degrees, silicon melts in molten iron to form ferro silicon alloy.
Use
1. The Ferro Silicon Alloy is used as deoxidizer and alloying agents in the steel industry. In order to obtain qualified chemical composition and guarantee the quality of steel, in the last stage of steelmaking must be deoxidized. The chemical affinity between silicon and oxygen is very large, thus Ferro Silicon is strong deoxidizer used in sedimentation and diffusion deoxidation of steel-making. Add a certain amount of silicon in the steel, can significantly improve the strength, hardness and elasticity of steel.
2.The Ferro silicon Alloy can also be used as an alloying element additive, and ferro silicon is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferro silicon is often used as a reducing agent in the production of ferro alloys and the chemical industry.
