| 摘 要： | 本文分析了喷吹煤粉对高炉风口的磨损机理，建立了预测风口磨损的数学模型，并对模型进行了求解，结果表明，风口因磨损而破损的寿命与喷吹量，风口材质，风口几何尺寸及热风速度等因素有关。

| Abstract: | The mechanisms of BF tuyere erosion due to pulverized coal injection (PCI) was analysed and a mathematical model was developed to predict the erosion. The calculated results of the model show that the service life of the tuyere due to PCI erosion has a very close relation with injection rate, characteristics of tuyere materials, geometrical shape of the tuyere and blast velocity etc. |

| Keywords: | blast furnace tuyere/erosion pulverized coal injection |
