Foundry Grade Black Silicon Carbide 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.
Foundry Grade Black Silicon Carbide has made carbon alloyed in it, so it can provide the two elements effectively. Lately Foundry Grade Black Silicon Carbide also be used in steel making, especially steel scraps melting. Foundry Grade Black Silicon Carbide 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.
Foundry Grade Black Silicon Carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw marterials .Foundry Grade Black Silicon Carbide hardness is between fused alumina and synthetic diamond.Mechanical intensity of it is higher than fused alumina .Foundry Grade Black Silicon Carbide is brittle and sharp has electrical and heat conductivity in some degree.The abrasives made of it are suitable for working on cast iron,non-ferrous metal,rock, leather,rubber,etc.It is also broadly used as refractory material and metallurgical additive.
