Ferro silicon is a kind of ferro alloys which is integrated of silicon and iron. The ratio of the two chemical substances are combined different, with the proportion of silicon ranging anywhere between 15% and 90% . Ferro Silicon 65 is using coke, steel chips and quartz (or silica) as raw materials, after high temperature reduction of 1500-1800 degrees, silicon melts in molten iron to form ferro silicon.
Ferro silicon from the Zhenan ferroalloy factory is a ferrosilicon alloy composed of silicon and iron in a certain proportion and is mainly used for steel smelting and metal magnesium smelting.
