Abstract:An improved mathematical model for the whole range moisture transfer process of iron ore sintering, based on the fundament of simultaneous heat and mass transfer in the moist zone, has been developed. On the basis of this model, the moisture transfer process during sintering was simulated numerically using computer.The model can serve as a predictive tool and operating guide for controlling the termperature in bed, determining suitable moisture level of raw mix and decreasing the harmful influence of  overmoistened zone.
