A Mathematical Model to Predict the Erosion of BF Tuyere Due to the Pulverized Coal Injection
-
摘要: 本文分析了噴吹煤粉對高爐風口的磨損機理,建立了預測風口磨損的數學模型,并對模型進行了求解.結果表明,風口因磨損而破損的壽命與噴吹量、風口材質、風口幾何尺寸及熱風速度等因素有關.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.
