Model experiments on the particle coagulation in NaCl-aqueous solutions were made in an agitated vessel to learn the coagulation rate of inclusion particles in liquid steel. Polystyrene-latex particles, silica particles and alumina particles were tested at various agitation speeds, and coagulation coefficients were obtained by comparing the observed coagulation rate with the predicted rate by the Saffman-Turner model on turbulent collision. The Higasnitani theory which considered the effect of van der Waals force and viscous resistance force on the coagulation coefficient was applied to obtain the Hamaker constant from the measured coefficients. Based on the measured Hamaker constants, the coagulation coefficients of inclusion particles in liquid steel were predicted for several steelmaking processes with different stirring intensities.
