Fe-C Composite Pellets for BOF (Basic Oxygen Furnace) are high-performance spherical alloy materials engineered through advanced composite technology. By precisely mixing iron powder and carbon powder, these pellets offer exceptional oxidation and corrosion resistance, coupled with superior elasticity and extensibility, making them an essential additive for modern steelmaking.
Specifically designed to optimize the steel-making process, Fe-C composite pellets significantly enhance production efficiency and steel quality. By shortening tap-to-tap time and reducing overall production costs, these pellets ensure a safer and more streamlined operation while maintaining the stringent purity levels required for high-grade steel production.
