Simulation Model for Temperature of Iron Ore Sinter Bed

Based on the physical chemical processes such as coke combustion,carbonate decomposition,drying and condensation of water and fusion and solidification of mixtures,a model for simulating the temperature of iron ore sinter bed has been set up on the basis of sintering theory by describing the process of heat and mass transfer between the material bed and exhausted air.Moreover,a simulation system for the sinter bed temperature has been designed and developed.Through this system,the temperatures of the material bed and air at any time and at any height can be calculated.The calculated results of the model are consistent with the practical results of sintering pot test,with the accuracy up to 90%.
