Simulation on Agglomeration of Liquid Inclusion Particles in Steel Based on VOF Model

Abstract

The Micro agglomeration process of liquid inclusion particles in static steel was simulated based on VOF model of fluent software. The results were indicated that: two liquid inclusion particles, which are apart from a certain surface distance, can aggregate into a larger new inclusion particle; in order to promote liquid inclusion particles aggregate and accelerate inclusions flotation to be removed, the following measures can be taken: shortening the inclusion particle surface spacing, reducing the steel viscosity and controlling the composition of liquid inclusion in high interfacial tension area.
