    Abstract
  • The dissolution kinetics of Al2O3 in CaO–Al2O3–SiO2 slags was studied using a high-temperature confocal scanning laser microscope at 1773 to 1873 K. The results show that the controlling step during the Al2O3 dissolution was the diffusion in molten slag. It was found that the dissolution curves of Al2O3 particles were hardly agreed with the traditional boundary layer diffusion model with the increase of the CaO/Al2O3 ratio of slag. A modified diffusion equation considering slag viscosity was developed to study the dissolution mechanism of Al2O3 in slag. Diffusion coefficients of Al2O3 in slag were calculated as 2.8 × 10−10 to 4.1 × 10−10 m2/s at the temperature of 1773–1873 K. The dissolution rate of Al2O3 increased with higher temperature, CaO/Al2O3, and particle size. A new model was shown to be ${v}_{{\mathrm{A}\mathrm{l}}_{2}{\mathrm{O}}_{3}}=0.16\times {r}_{0}^{1.58}\times $$ {x}^{3.52}\times {\left(T-{T}_{\mathrm{m}\mathrm{p}}\right)}^{1.11} $ to predict the dissolution rate and the total dissolution time of Al2O3 inclusions with various sizes, where $ {v}_{{\mathrm{A}\mathrm{l}}_{2}{\mathrm{O}}_{3}} $ is the dissolution rate of Al2O3 in volume, μm3/s; x is the value of CaO/Al2O3 mass ratio; R0 is the initial radius of Al2O3, μm; T is the temperature, K; Tmp is the melting point of slag, K.
