摘要
鼓风机投入运行仅一年多因叶轮突然断裂而发生爆炸。对断裂的叶轮材质进行了化学成分及力学性能测定 ,并用光学显微镜及扫描电镜对材料的组织及断口进行了检验。检验结果表明 ,热处理工艺控制不当及叶轮材料中存在的锻造缺陷 ,是导致裂纹产生。
Wheel fracture caused blower explosion after one year's operation. Mechanical properties, microstructure and fractograph of the failed wheel were examined. It was concluded that forging defects and improper heat treatment of the wheel caused crack initiation, leading to brittle fracture.
