Description
Ferro Silicon used coke quartz(or silica)as raw material is made by electric furnace, because silicon and oxygen are easily compound into SiO2, the Ferro Silicon is often used as deoxidizer in steeling. It also can be used as a suspended phase in the mineral processing industry and coating for welding electrodes in the electrode manufacturing. According to the content of Silicon, this product can be divided into FeSi with the Si content: 75%、72%、70%、65%、60%、45%.
