Foundry Grade Black Silicon Carbide
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.
