摘要
在对一台锅炉主蒸汽阀门的磁粉检测过程中,发现多处密级裂纹缺陷,文中通过微观下的理化检测对裂纹微观形成原因进行分析,并提出合理化建议。
During the magnetic particle testing process of a boiler,multiple dense cracks were found.In the main steam valve.This article analyzes the micro formation reasons of cracks through physical and chemical analysis.Drawing from this analysis,the study offers practical and reasonable recommendations for addressing these cracks and preventing future occurrences.
