Abstract

The interfacial property is the key factor to determine the solubility and absorption of solid inclusions by mold flux in the continuous casting process. In this study, the interfacial interactions between slag droplet and TiO2, TiN substrates were investigated by sessile drop method. By processing the image of the experimental process, it could be found that the molten flux has a good wettability for both TiO2 and TiN substrates. A large number of bubbles were observed on the surface of the droplet during the reaction between the droplet and the TiN substrate, which indicated that TiN was oxidized by liquid mold flux. Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) were used to observe the reaction interface of the sample after the sessile drop test, and the results showed that the final products of interfacial interaction between the slag droplet and TiO2 substrate are perovskites and that for TiN substrate are also perovskites.
