- 1-Wettability between Molten Slag and Dolomitic Refractory

In the current study, the wettability between molten slag and dolomitic refractory materials used in the ladle during steel refining was investigated. The contact angle between molten slag and dolomitic substrate decreased with increasing temperature. The slag with lower basicity spread on the substrate more easily and penetrated deeper into the substrate. The penetration depth of slag into the refractory increased with the extension of holding time. The CaO in the refractory dissolved into slag which was then saturated with CaO. The reaction between slag and substrate resulted in the formation of solid Ca3SiO5, which slowed down the further penetration of slag into the refractory.
