The ferro silicon granule is silver grey, grain, and it is mainly used in smelting, steelmaking and casting. It takes the coke, scrap steel, and silica as raw materials, which is made by the electrosmelting.
The ferro silicon granule is bright grey, and the density is small. The more silicon, the lower proportion. According to the content of the silicon, it can be divided into industrial ferrosilicon (Si > 97%, iron does not exceed 1.5 percent), and the ferrosilicon of different contents of silicon, 95%, 75%, 65% and 45%, etc.
Melting Point: 1080-1250 ° C
Weight proportion: 4.7-5.4
