Abstract
The volume of fluid (VOF) method coupled with an overset mesh is used to simulate the dynamic motion of particles passing through the steel–slag interface. The results show that the solid inclusion particles with a diameter of 10 μm will sink first and then rise in a short time with a wide range of interface deformation when they approach the interface, and the motion state is extremely unstable. The liquid inclusions under the same conditions are also accompanied by unstable motion, but the raised meniscus will play a role in accelerating the upward movement. Increasing the terminal velocity of particles, improving the wettability of particles in molten steel, and modifying solid inclusions into liquid inclusions can reduce the oscillation amplitude during particle movement, which is conducive to the stability of particles at the liquid–liquid interface. The viscosity of slag has little effect on the detachment motion of small particles.
