摘　　要：主要研究了30Cr Mn Si活塞杆球头淬火工艺。为减少球头的淬硬层深度,设计了冷却筒实验工装,通过调整工艺参数,并结合硬度测量和金相组织分析方法,研究结果表明：830±10℃淬火,水冷,淬硬层深度为10 mm,硬度值HRC35~40,完全满足设计要求。Mainly studied the quenching process of the piston rod ball head in 30CrMnSi. In order to reduce the depth of the ball head hardened layer, the experiment equipment of the cooling cylinder was designed. By adjusting process parameters, and combined with the analytical method of hardness measurement and metallographic structure, results of the study showed that 830＋10℃ quenching, water cooling, depth of the hardening layer was 10 mm, and hardness value was HRC35-40, fully meeting the design requirements.
