s 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 alumina-
magnesia 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
