The fractal properties and floating features of agglomerated inclusions are investigated by the analysis of fractal theory and water simulation experiment. The results show that there is an obvious quantitative relationship between the aggregate floating velocity, the number of tiny inclusion granules and fractal dimension. Namely, for the aggregates which contain the same number of micro granules, the greater the fractal dimension, the larger the floating velocity; for the aggregates which have the same fractal dimension, the more the number of tiny inclusion granules contained by an aggregate, the larger the floating velocity. The mathematical model obtained by regression analysis can better reflect the relationship between the aggregate floating velocity, the number of tiny inclusion granules and fractal dimension. So in order to increase the floating velocity of aggregated inclusion with small fractal dimension, some appropriate measures of making it reconstruct to increase its fractal dimension can be taken.
