Research status and prospects of the iron ore’s high temperature behaviors in the sintering process

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.
