Heat transfer in the steelmaking process is important for controlling final product quality. Uncontrolled heat transfer leads to thermal stresses during cooling, subsequently producing stress fields and cracks. The research of thermal conductivity of mold flux can improve the surface quality during initial solidification. The effect of CaO/SiO2 and B2O3 on the thermal conductivity of the mold flux for high-carbon steel has been measured using the hot wire method to investigate the relationship between the thermal conductivity and structure. The network structure of molten mold flux was analyzed using FTIR and Raman spectroscopy. The optimal conditions for high-carbon steelmaking process could be reached from a combination of thermal conductivity data and structural analysis.
