摘要

In order to evaluate quantitatively the distribution of coke breeze in the quasi-particles, the granulation experiment was carried out by using limonite iron ores and coke breeze, and the effects of particle size of iron ore and coke breeze on granulation properties were examined. Moreover, quantitative analysis of coke breeze in a quasi-particle was carried out. The results obtained are follows:(1) Regardless of the brand of iron ores and existence of nuclei, the quasi-particle diameter became smaller when coke breeze was added and it became smaller when the particle size of coke breeze became larger. It is thought that the adhesion force by the liquid bridge became smaller because the contact angle between coke and water is larger than that between iron oxide and water.(2) The coke contents of P-type quasi-particles without nuclei are almost constant regardless of its diameter because they are equally growing by adhering of the fine iron ore and coke breeze uniformly.(3) In case of C-type quasi-particles containing nuclei, the adhering fines layer of C-type quasi-particles is growing by adhering of the fine iron ore and coke breeze uniformly until about 5 mm diameter of it. Consequently, the coke contents in the adhesion fines layer of C-type quasi-particle are almost constant regardless of its diameter. Moreover, it is thought that the peak of carbon content at over 5 mm diameter exists by coalescing of each granule.
