There are multi-interphase phenomena occurring in the continuous casting mold, such as shell versus molten flux, inclusions versus molten steel, molten steel versus gas bubbles, etc., which makes the interfacial phenomena very complex. The interfacial property between liquid mold flux and steel has significant impact on the quality of casting slab. The slag entrapment in mold tends to cause severe defects on slab surface, especially for casting steels containing active alloy elements like Al, Ti, Mn, etc. Therefore, the wetting behaviors of mold flux on steel substrate were in situ observed and investigated using the sessile drop method. The microstructure and element distribution across the slag-metal interface were analyzed by SEM and EDS for further investigation of the relationship between the wetting behavior and chemical reaction at mold flux/steel interface. The results obtained in this study can provide a new sight to design mold flux and improve slab quality.
