The permeability index is a very important parameter of the Imperial Smelting Furnace(ISF) ,which reflects the production status of the furnace. The accurate prediction of the permeability in the Imperial Smelting Furnace is meaningful for increasing the output of ISF. In this Paper, the grey system theory is introduced. With the help of this theory, a predicting permeability model of ISF is established, which based on grey theory has overcame the difficulty for the lack of data and the disadvantage of the neural network抯 slow collecting speed. According to this model, the practical data of ISF are simulated and the simulating result is close to actual data. It proves the model has some degree of accuracy. This method is practical, effective and has important referenced value for technician to adjust the status of the furnace.
