摘要
采用低倍检验、化学成分分析、扫描电镜及能谱分析、金相检验等方法对50 t加氢锻件筒体超标缺陷进行了分析。结果表明:该加氢锻件筒体缺陷为夹渣,夹渣的主要成分为Ca O、Al2O3等。
By means of macroscopic： examination, chemical composition analysis, SEM and EDS, melallographic examination etc, the defect beyond tolerance of 50t hydrogenation cylinder forging has been analyzed. It turned out that this kind of defect was slag inclusion whose major composition was CaO anti Al2O3 etc.
