To utilize pisolite ores as raw materials of iron ore sinter, a commercial production trial was carried out by designing the structure of quasi-particles. Main results obtained from the trial are summarized as follows:<br>(1) The commercial production test using 40 mass% pisolite ores in raw materials showed that high quality sinter was produced by making quasi-particles having duplex structures; the inner core is granulated by raw materials containing the pisolite ores and the outer shell is coated with both coke fine and high grade magnetite ore fines. <br>(2) According to the reduction kinetic analysis of sinter products, high reducibility of the products produced from quasi-particles having the duplex structure results in the improved reduction rate parameters resulting from the product structures containing many micro-pores ranged from 10 to 100μm.<br> (3) Improved reduction degradation characteristics of the products depend on decreased hematite phase and increased magnetite phase in the sinter structures as well as micro-pore distributions.
