Ferro Silicon 75% 72% 10-50mm
Ferrosilicon is a ferroalloy composed of iron and silicon. Ferrosilicon is an iron silicon alloy made from coke, steel chips,quartz by electric furnace smelting
Description
Description
Ferro Silicon is a universal “heat-blocker” used in the production of carbon and stainless steels. This additive is used with other ferro alloys in the deoxidising process of steel, as well as in the production of silicon itself. It is also used in the production of cast iron, as it can accelerate graphitisation. Ferro Silicon replaces the need for ferro manganese, spiegeleisen and calcium silicides in the manufacturing process.

Advantage
It is main used in foundries. As you know the cast iron contain C: 2-4%, Si: 1-3%, and Carbon and silicon are the main elements affecting the microstructure of cast iron.High Carbon Silicon has made carbon alloyed in it, so it can provide the two elements effectively. Lately it also be used in steel making, especially steel scraps melting. It serves as deoxidizer and efficient heating agent (Si&C: 6.58kcal/g, 1.24kcal/g each) and recarburizer. With Si&C at least 90%, the impurity is very less, so the input is easy to control.
