As the lining of metallurgical vessels, refractory material is in direct contact with moving molten steel during the entire refining process. The dynamic interaction between molten steel and refractory material will seriously affect the service life of refractory lining and restrict the smelting safety and efficiency of steelmaking. In this paper, experiments on the interaction between aluminamagnesia castable and molten steels under dynamic smelting conditions were performed. The corrosion behaviour of molten steel on the alumina-magnesia refractory and the effect on the steel cleanliness was analysed and discussed. The corrosion mechanism of the alumina-magnesia refractory was revealed. The modified capillary number (Ca) can be used to compare the refractory wear by estimating the critical velocity of the emulsification. Furthermore, the empirical formulas for the emulsion droplet size were established, the formation and evolution mechanism of the inclusions was illustrated, which provides guidance for the application of refractory materials in the smelting of high quality steel
