The Steel industry uses two primary processes in the production of steel. The traditional integrated mill melting iron ore in a BOF (Basic Oxygen Furnace) and EAF (electric arc furnace) using recycled steel & iron scrap as raw materials. Silicon Carbide is an important additive contributing to oxidation and reduction reactions enhancing the mechanical properties of steel.
