摘要

The motion and dissolution of Al2O3 inclusions in a 260-ton argon-stirred steel ladle were numerically simulated using the DPM model. Inclusion dissolution by slag was realized by dynamically modifying the inclusion diameter, and removal was determined by comparing the diameter with a critical value. The average removal time rose slightly from 134.1 to 150.9 seconds as the diameter increased from 1 to 10 μm, and sharply to 729.8 seconds at 100 μm.
