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°C quenching, water cooling, depth of the hardening layer was 10 mm, and hardness value was HRC35~40, fully meeting the design requirements.
