Synthesized all above, the heat and mass transfer of charge bed is discussed in detail. After choosing seriously the former study results in this field, a whole temperature range process model for firing iron ore pellets containing solid fuel is established as well as its software is edited. The main physical chemistry reaction process within pellets and the heat statement can be calculated exactly with the process as long as the physical and chemical parameters of raw material are obtained through basic experiments. After finding out the reason of"temperature hysteresis"and"heat inertia"of the experimental induration device, a new kind of experimental induration device is designed. The"temperature hysteresis"of hot gas flow in the new device is avoided.
