摘　　要：为解决无缝钢管厂存在的Φ130,90mm自动轧管机组球形顶头(材质Cr35Ni4Si高铬镍铸钢)质量差、寿命低等问题,对其使用条件和影响因素进行了探讨。通过调整自动轧管机球形顶头的成分,增设热处理工序等措施实现优化自动轧管机球形顶头的生产工艺。实践证明,采用上述改进措施,尤其是增设热处理工序后,自动轧管机球形顶头的性能得到显著改善,使用寿命提高4倍以上。Addressing the problems concerning the spherical plug （material： Cr35Ni4Si cast steel） of the Ф 130, 90 mm plug mill of the seamless steel pipe plant, including poor quality and short service life, etc., relevant application conditions and influencing elements are discussed. The manufaturing process for the plug mill spherical plug is optimized by means of taking actions like rimming the chemical composition of the plug material and additional heat treatment process. Relevant operation practice shows that thanks to these actions as taken, particularly the heat treatment process, the properties of the said spherical plug is significantly improved, and its service life is four times longer than before.
