ISO approval ferro silicon 75 72 65 best price
Description :
1.Ferro Silicon is a kind of ferroalloy which is composed of ferrum and silicon.
2.Ferro Silicon uses coke, quartz (or silica) as raw materials and is made by electric furnace. Becausesilicon and oxygen are easily compound into SiO2, the ferrosilicon is often used as deoxidizer in steelmaking.
Application :
1). Iimprove the hardness, strength, elasticity and permeability of steel
2). Lower the hysteresis loss of the transformer.
3). To prevent the formation of carbides.
4). Promote the precipitation and nodulization of graphite.
5). Perfect the performance and nature of casting iron
