The tiny non-metallic inclusion in a molten steel could be removed effectively when they collide and coalesce under the electromagnetic vibration. The viscosity resistance enforced on the particle is related to particles structure, surface status, size and movement velocity when inclusions are moving in the liquid. In order to study the collision and coalescence mechanism a water model experiment was conducted by using the porous particles made by glass fibers, which are simulated to dendritic inclusions. The falling process of the particles that was enforced by the gravity and the behavior when two particles that have the same diameter but difference solid fractions are approaching were observed by a high-speed camera, and then the velocity of the particles are calculated. According to the experiment results, the motion equation of the porous particles is derived. Moreover, the equation is examined by the model experiment. The approaching behavior of two particles is analyzed in the plane of the moving velocity and relative distance. The velocity change of the particles is very large when the large solid fractions are approaching, which means that strong liquid repelling resistance exists between the particles. The liquid repelling resistance is weak between the small solid fractions, which predicts that the particles are easy to collide and coalesce.
