Abstract: As to solve the online monitoring of the inner temperature and freezing profile of the reaction shaft of flash smelting furnace, simulation of the wall in the reaction shaft in a flash smelting furnace was made through numerical computation. The computational results are very near the data got in site. The error of the moving boundary is approximately 3%, and that of the temperature is less than 5%. It is proved that the simulation software is applicable for practice tomonitor the temperature and moving boundary inside the hearth online. Based on a large number of the data computed, the relation between the change of the moving boundary and inner temperature is summarized, and the great influence of the cooling system on the forming and stability of the moving boundary inside the hearth is emphasized, which provide the theoretical bases for optimizing the flash smelting operation.
