Ferro Silicon

Ferrosilicon is produced by reduction of silica or sand with coke in the presence of iron.

Ferro silicon. Typical sources of iron are scrap iron or 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. It contains a high proportion of iron silicides. In commercial terminology it is defined as a ferro alloy containing 4 or more of fe more than 8 but not more than 96 of si 3 or less phosphorus p 30 or less of manganese mn less than 3 of magnesium mg and. Ferrosilicon is a gray color ferroalloy product which is made of iron and silicon.

Its melting point is about 1200 c to 1250 c with a boiling point of 2355 c. Ferrosilicon ferro silicon iranian ferrosilicon is a kind of ferroalloys which is integrated of silicon and iron. Ferrosilicon or ferrosilicium is a ferroalloy an alloy of iron and silicon with between 15 and 90 silicon. This alloy is also known by the name of ferrosilicium.

Different content of si fe al etc in ferro silicon different grade of ferro silicon the most widely used is 75 ferrosilicon and 72 ferro silicon. The ratio of the two chemical substances are combined different with the proportion of silicon ranging anywhere between 15 and 90. Ferrosilicon is also important as an additive to cast irons for controlling the initial content of silicon.
