摘　　要：本文设计了厚壁钢管的半浸式淬火工艺试验。结果表明,与传统的外淋内喷式淬火工艺相比,半浸式淬火后钢管的全壁厚淬火硬度值及其均匀性、头尾两端性能稳定性及全长的屈服强度和抗拉强度极差稳定性均有改善。The semi-immersion quenching process test of thick walled steel pipe was designed.The results showed that compared with the traditional external spraying and internal spraying quenching process,the quenching hardness value and its uniformity,the performance stability of the head and tail ends,the yield strength and tensile strength extreme difference stability of the whole length of the steel pipe produced by the semi-immersion quenching process were improved.
