Abstract

Dissolution kinetics of alumina into a new type CaO-Al₂O₃ mold slag was investigated by employing the rotating cylinder method. The results shows that the alumina dissolution was controlled by the mass transfer in the molten slag; the diffusion coefficient D=4.2×10^-5mm²/s under 1400°C; the activation energy of dissolution process was 213.8 Kj/mo1, this energy was higher than that of traditional mold slag; the ability of the new mold slag to absorb Al₂O₃ was weaker than that of traditional mold slag.
