Theory and Experimental Research on Inclusions Aggregation in Molten Steel

A mechanism of particles aggregation in liquid media is analyzed by applying the theory of aggregation which was developed in the field of colloid engineering. Hydrophobic particles are liable to aggregate in collision. Inclusions aggregation by using solid plastics particles in various solvent is observed in the course of floatation. Aggregation rate and size distribution of particles in turbulent dispersions has been studied. The aggregation contributed by plastic particles based on surface energy density and the droplet surface oscillation is considered. Hydrophobic particles, generally having a tendency to aggregate in water, disperse well in ethanol, particles in the mixture of water and ethanol are much better disperse than separately in water. The solvent properties, temperature and simulation particles are influence to the aggregation from the experiment that we can discover. The aggregation rate and size distribution were determined by wettabiliy.
