摘要
针对焦炉煤气鼓风机在使用过程中出现叶轮断裂的问题,通过采用改进制造工艺、对断裂的叶片和铆钉进行物理化学分析、对破坏断口进行宏观及微观研究等措施,得到焦炉煤气鼓风机叶轮断裂原因。研究表明:制作工艺和应力腐蚀是焦炉煤气鼓风机断裂的主要原因。
the use of coke oven gas blower impeller fracture problem arising in the process,through the adoption of improved production technology,on the broken blade and rivets for physical chemical analysis of the destruction of macro-and micro-fracture study,to be causes of coke oven gas blower impeller fracture.Studies have shown that:production processes and stress corrosion is the main reason for fracture of coke oven gas blower.
