As the core raw material of the sintering process，the effective identification of the quality difference between the two piles before and after the blending ore and the management for changing pile have a direct impact on the quality stability of the sinter. In order to solve the problems of quality fluctuation and low operation efficiency in the traditional blending ore and changing piles operation，an intelligent changing piles solution is proposed. By integrating the data communication between the raw material yard and the sintering process，an online transmission and processing system is established for matching the blending ore and changing piles ratio and quality test data，and on this basis，many intelligent control models are established，such as the preparation of changing piles plan，the changing piles operation，the changing piles quality adjustment and the daily quality adjustment，which greatly lower the difficulty of the changing piles operation and improves the accuracy of changing piles control. After the implementation of this scheme，the preparation time of the changing piles plan is shortened from more than 3 h to less than 0. 5 h，and the operator can automatically complete the entire changing piles process with a simple one-click operation. On the day of changing piles，the alkalinity stability rate is increased by 11. 3% on average，and the FeO stability rate is increased by 4. 4% on average.
