3mm Ferro Silicon 65 Granules As Industrial Spheroidizing agent
Ferrosilicon Description
Ferrosilicon, often abbreviated as FeSi, is an alloy of iron and silicon that also contains small amounts of other elements. The most popular ferrosilicon grade contains 75 wt% silicon ("FeSi75"), but levels range from 15-90 wt%, depending on the application.
The highest quality ferrosilicon is made in an electric arc furnace by reducig silica with coke in the presence of iron (usually from scrap steel or iron ore). Ferrosilicon usually comes in shiny metallic gray blocks but is also available in pre-formed blocks.

Ferrosilicon Application
1) Used as deoxidizer and alloying agents in the steel industry.
(2) Used as nucleating agent and spheroid zing agent in the iron industry. Adding a certain amount of ferrosilicon in iron cast can reduce the carbide of the iron and Promote the precipitation and nodulizing ofgraphite.
(3) Fesi 75% alloy is the main raw materials of producing metal magnesium, tons of consumption is at about 1.1 tons.
Packing & Delivery
