Quality Metal Product Ferro Silicon Chinese Supplier

Ferro Silicon is a kind of ferroalloy which is composed of ferrum and silicon. Ferro Silicon uses coke(or silica) 

as raw materials and is made by electric furnace. Because silicon and oxygen are easily composition into 
SiO2,  the ferrosilicon is often used as deoxidizer in steelmaking. 


1. Ferrosilicon is often used as deoxidizer in steel- making.   

2. Ferrosilicon also can be used as alloy elements join agent,  which is widely used in low alloy steel,  non-       ferrous metal,  bearing steel,  heat-resistant steels and electrician silicon-steel. 

3. It can be used as a reductant in ferroalloy production and chemical industry. 

4. In iron industry it can be used as inoculant and nodulizer.

Our Service and Quality Promise:      
1.Reply your inquiry in 24 working hours.
2.Try our best to meet different customer's needs.   
3.Test the goods before leaving our factory
4.Welcome to visit our factory at any time
5.The content packing particle size may be based on customer demand.
6.We are aimed at doing the best alloy in China.   

Ferro Silicon(FeSi) is a co-product of Brown Fused Alumina during fusion,so also called Brown Fused Alumina Slag. During fusion of aluminum oxide based bauxite, heavy elements in the electric arc furnace goes down to bottom of the furnace. After cooling down, they become silver/grey ores which contain Ferro and Silicon. In our industry, we call them Brown Fused Alumina Slag.

After crushing and sizing, it's made into different grits suitable for steel making industry as media separation or sink float process to remove oxygen from high quality steel or cast iron. Main users of FeSi are producers of alloyed, carbon or stainless steel.

According to content of Ferro, we make mainly 2 quality: 72% Ferro FeSi and 80% Ferro FeSi.
