Hot Slag Modification with Mechanical Stirring: Motion and Dispersion Characteristic of Modifier Particle

To improve the modification efficiency and effect of hot slag with mechanical stirring, motion dispersion characteristic modifier particles stirring time are investigated by numerical simulation, entrainment mechanism particle was discussed. In addition, a quantitative index suitable for discrete simulation is proposed effects speed impeller structure on were also elucidated. The results show that four circulation streams each side cross-shaped which beneficial to complete mixing between slag. depends axial velocity turbulent kinetic energy surface. A dynamic steady state in region can be obtained within 8 s stirring. 60 rpm more conducive modification.
