摘要

承制的某加氢反应器筒节锻件在调质后出现批量性能不合格质量问题,通过缺陷分析,查找原因,并在后续生产中制定了有效预防措施,保证了后续生产加氢筒节全部一次调质合格。
        After quenching and tempering,the performance of a certain hydrogenation reactor shell forging in batch has been found to be unqualified. The reasons have been found through defect analysis,and effective preventive measures have been formulated to ensure that all the hydrogenation reactor shell forging in the subsequent production have been qualified after the first quenching and tempering.
