To explore the effect of refractory on the evolution of inclusions, laboratory experiments were conducted with MgO refractory utilizing electron probe X-ray microanalysis. Based on primary inclusions components, six types of inclusions were observed in the steel with MgO refractory: Al2O3, Al2O3-MgO, Al2O3-CaO, Al2O3-MgO-CaO, Al2O3-SiO2-CaO, and MgO inclusions. Al(2)O(3)and Al2O3-MgO inclusions were the primary inclusions and mainly attributed to deoxidization products, with liquidus temperature exceeding 1600 degrees C. Al2O3-MgO-CaO inclusions resulted from coalescence between MgO and Al2O3-CaO inclusions as well as reduction of Al2O3-CaO by dissolved Mg. Dual-phase Al2O3-MgO-CaO inclusions were characterized by pure MgO cores surrounded by liquidus Al2O3-CaO layer, which was related to the substitution of dissolved Ca and Al in molten steel for MgO in inclusions.
