high carbon silicon

H.C Silicon High carbon silicon metal comes from leftover material of silicon metal producing, a caking at bottom of the furnace. Elemental silicon content is usually between 40-70% and carbon content is 10-25%. High carbon silicon is normally used as a low cost substitute of ferrosilicon, silicon carbide and recarburizer which effectively reduce the cost of steelmaking. High Carbon Silicon has made carbon alloyed 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.   si: 65%min C: 15%min Si: 68%min C: 18%min
