Fe-C Composite Pellets for BOF (Basic Oxygen Furnace) are high-performance spherical alloy materials engineered using advanced composite technology. By precisely mixing iron powder and carbon powder, these pellets provide a superior solution for recarburization in steel-making, offering exceptional oxidation resistance, corrosion resistance, and structural stability during the smelting process.
Specifically designed to optimize the steel-making cycle, these composite pellets play a critical role in improving the overall efficiency of production. By implementing Fe-C pellets, manufacturers can achieve higher steel quality, significantly shorten tap-to-tap time, and reduce operational costs while enhancing the safety standards of the entire production environment.
