Fe-Si is used to produce cast iron as a purifying agent. Fe-Si is used to remove carbon from the cast iron melt. If the Fe-Si were contaminated with high levels of carbon, then the carbon would render the cast iron out of spec.The final product produced by the customer of the smelter would be steel.
