Fe-C Composite Pellets for BOF (Basic Oxygen Furnace) are high-performance spherical alloy materials engineered using advanced composite technology. By precisely blending iron powder and carbon powder, these pellets offer superior oxidation and corrosion resistance, along with excellent elasticity and extensibility, making them an essential additive for modern steel-making processes.
Designed to optimize the efficiency of steel production, Fe-C composite pellets significantly reduce tap-to-tap time and production costs while enhancing the overall safety and quality of the final steel products. Their low trace element profile ensures the production of clean, high-grade steel tailored to rigorous industrial standards.
