摘要：
The dissolution behavior of complex inclusions in refining slag was studied using confocal laser scanning microscope. Based on the dissolution curve of complex inclusions, the main rate-limiting link of CaO–SiO2–Al2O3 complex inclusions was the diffusion in the molten slag. The dissolution rate of CaO–SiO2–Al2O3 complex inclusions was affected by the composition and size of inclusion. The functional relationship between the dimensionless inclusion capacity (Zh) and the dimensionless dissolution rate (Ry) of CaO–SiO2–Al2O3 complex inclusions was calculated as Ry=2.10×10-6Zh0.160\documentclass[12pt]{minimal}

\begin{document}$$Ry = 2.49 \times 10^{ - 6} Zh^{0.087}$$\end{document} for Al2O3–CaO complex inclusions. On this basis, the complete dissolution time and rate of the complex inclusions were calculated by using the function relation between the Zh and Ry numbers.
