Multiphysics Numerical Simulation Model and Hydraulic Model Experiments in the Argon-Stirred Ladle

The argon-stirred ladle is a standard piece of steelmaking refining equipment. molten steel quality will improve when good process applied. In this paper, Multiphysics model that contained fluid flow, bubble transport, alloy heat flux, melting, and an concentration species transport was established. were used to calculate the velocity verified by hydraulic combined with particle image velocimetry measurement results. numerical simulation results temperature fields steel–slag interface shape 25 t in plant. difference between decreased CL (integral time-scale constant) increased from 0 0.3; then, 0.3 0.45. showed approached experiment more. flux examined industrial practice, decrease rate 0.0144 K/s. initial decreased.
