In the current study, the fluid flow and desulfurization in a 160 t KR ladle was simulated using FLUENT combined with user-developed subroutines. The velocity distribution of the hot metal, the motion and distribution of CaO particles, and the desulfurization rate of the hot metal were calculated. With the increase of the rotation speed of the impeller, the velocity of the hot metal was increased, and the fraction of the dead zone was decreased. The velocity of the CaO particles increased as well, which increased the desulfurization efficiency. The desulfurization rate varied at different positions of the ladle, with a higher rate in the higher speed zone and slower in the dead zone. The desulfurization rate increased slightly with increasing rotation speed of the impeller. When the particle diameter increased from 1.3 mm to 2 mm, the desulfurization rate decreased approximately 3 or 4 times.
