Abstract

The rate of solution of A12O3 in CaF2 + 30 wt pct A12O3 (at 1518° and 1509°C) and CaF2 + 20 wt pct A12O3 (at 1500°C) liquids has been determined. The operative process is diffusion-controlled, with an interdiffusion coefficient,D for the process varying between 8.5 and 8.1 x 10-5 sq cms - 1 in the CaF2 + 30 wt pct A12O3 slags, and 4.0 × 10-5 sq cms - 1 in the CaF2 + 20 wt pct A12O3 slag. Estimations of the rate at which alumina inclusions would react with these slag during the electroslag processing of steels, indicate that electrode inclusions approaching 100 μ in diam will be dissolved.
