摘要
对穿孔无缝钢管热穿孔顶头的失效机制和使用状况进行了分析研究，认为穿孔顶头的失效形式主要表现为顶头塌鼻、粘钢、开裂，提出了利用稀土铝合金化提高顶头使用寿命的措施，并对该措施的可行性进行了论证。
The failure mechanism and service status quo of hot piercer point in seamless steel tube were analyzed and its failure was mainly caused by piercer point col- lapsing nose ,sticking steel and cracking. One way to enhance the service life of piercer point by means of Re-Al alloying was offered and its feasibility was proved in this pa- per.
