Ferrosilicon is a gray color ferroalloy product which is made of iron and silicon. 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 . As we know that in the steelmaking industry, about 3-5 kg of 75% ferrosilicon is consumed for every 1 ton of steel produced.Calcium Silicon Cored Wire, Calcium Cored Wire, Ferro Silicon Cored Wire. It is made by wrapping alloy powder with steel strip. According to different inside alloy powders, it can be divided into: silicon calcium cored wire, silicon manganese calcium cored wire, silicon calcium barium cored wire, barium aluminum cored wire, aluminum calcium cored wire, calcium iron …Silicon calcium cored wire is a ferroalloy product made by grinding silicon calcium into powder as a core material and putting it into the cored wire.
