Market price of ferrosilicons 

Info of Ferro Silicon

Ferrosilicon is produced by reduction of silica or sand with coke in presence of iron. Typical sources of iron are scrap iron,millscale. Ferrosilicons with silicon content up to about 15% are made in blast furnaces lined with acid fire bricks. Ferrosilicons with higher silicon content are made in electric arc furnaces.

The usual formulations on the market are ferrosilicons with 15%, 45%, 75%, and 90% silicon. The remainder is iron, with about 2% consisting of other elements like aluminium and calcium. An overabundance of silica is used to prevent formation of silicon carbide. 

A mineral perryite is similar to ferrosilicon, with its composition Fe₅Si₂. In contact with water, ferrosilicon may slowly producehydrogen. The reaction, which is accelerated in the presence of base, is used for hydrogen production. The melting point and densityof ferrosilicon depends on its silicon content.

In the steelmaking 

As we all konw , Ferro Silicon can be used as deoxidizer and desulfurizer in the steelmaking. Usually , in order to improve the toughness and elasticity of steel, fesi used as additives is put into the liquid steel. 

Ferro Silicon uses coke, quartz (or silica) as raw materials and is made by electric furnace. 

Various sizes of ferro silicon

In the casting iron

Fesi can be used as inoculant in the foundry. Because it can promote the  graphitization of pig iron.

Fesi powder is used easily and facility as inoculant. And its inoculation effect is not bad. 

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