Highly efficient dissolution of CaO into melt has an important role in reducing the amount of steelmaking slag produced in the hot-metal dephosphorization process because the existence of free-CaO in the melt prevents reuse of the slag. There are numerous studies related to the rate of CaO dissolution, however, in many cases the experimental conditions have been limited. The present work measured the dissolution rate of CaO into several kinds of slags: FetO-CaO-SiO2-X (X; CaF2, CaCl2, Al2O3 and B2O3) systems at hot-metal temperatures. To apply the results to practical operations, the efficiency of additives in dissolving CaO in the melts was compared using "the enhancement factor" based on the results.
