In order to clarify the hydration characteristics of free CaO phase, the contents of divalent metal oxides in crystallized CaO phase in BOF, remelted BOF and synthetic slags were determined as functions of slag composition and cooling rate. The contents of divalent metal oxides increased by slow cooling to 1474 K, followed by rapid cooling so as not to precipitate the calcium ferrite phase in crystallized CaO phase. As a result, free CaO with the divalent metal oxides of more than 20 mass% was not corroded with ethylene glycol.
