To reduce refractory damage during steelmaking, precise control of slag composition is important. Usually, the formation and decomposition rates of interfacial layer are considered to be rate‐controlling steps. The influence of the interfacial layer on the dissolution rate was investigated. The reagents were mixed and sintered to make an oxide that simulated the interfacial layer. The sample was added to molten slag stirred by Ar gas, and the dissolution rate was determined from the change in slag composition. The results revealed the importance of the effects of the density and composition of the interfacial layer on the dissolution rate.
