Summary:Based on the careful analysis of the heat transfer mechanism of the cooling process of high temperature sinter, a one-dimensional unsteady state mathematical model for the gas-solid heat transfer process of high temperature sinter was established according to the energy conservation. The mathematical model was verified by the use of industrial practical data, and the results showed that it was correct and reliable. Lastly, the model was used to investigate the effect of operation parameters (such as the trolley moving speed and the cooling air velocity) on the cooling process of the annular cooler, and the proposals were put forward for optimising operations of the annular cooler.
