The pressure to reduce NOx emissions in iron ore sintering process is enlarging increasingly. The paper proposed a sintering granulation method to reduce NOx emissions. The main character of the method was to wrap all fuel on the surface of the pellet, and also increased the contact between iron ore and fluxes. The sinter-pot test results showed that NOx emissions of the method reduced by 19.9% and sinter quality improved, while SO2 emissions increased by 17.7% compared with that of the conventional method. The increase in the reducing atmosphere of the sinter bed and the development of calcium ferrite in sinter were the main causes of NOx emissions reduction and the improvement of the sinter quality. In addition, the promotion of the combustion of fuel resulted in the increase in SO2 emissions. The improvement of the sinter quality and the control of the sintering flue gas pollutants can also be realized through adjusting the distribution of fuel, fluxes and iron ore in the pellet reasonably.

The research status of the iron ore’s high temperature behaviors in the sintering process was reviewed in this paper. The influencing factors of the high temperature behaviors and their effects on the sinter performances were discussed, and the prospects of the optimization of ore proportioning based on the iron ores’ basic characteristics were also proposed. It is suggested that the melting behavior and infiltration behavior of the sintering liquid should be further investigated. Moreover, the limiting links of the sinter quality for different iron ores sintering should be analyzed by combining the basic characteristics and the production technology of the industrial sintering processes. Given priority to the low fuel ratio and the sinter quality, the complementary principles of the iron ores basic characteristics and mathematical models should be used in the optimization of ore proportioning.
