摘要
2Cr13活塞杆经过亚温淬火、回火调质后,采用580℃保温3～4h空冷或炉冷的稳定化工艺,基本上可以消除应力,并且没有明显的第二类回火脆性的产生,从而保证了2Cr13活塞杆高频淬火时减小弯曲量,避免感应器放电现象熔化活塞杆。
After the 2Cr13 piston rod passes through subcritical quenching and quenching tempering,the stabilization process of adopting air cooling or furnace cooling of 3~4h under 580 ℃ can basically eliminate the stress,and there is no obvious second tempering Brittle production.Thus it can ensure the amount of bending decreased when the 2Cr13 piston rod with high-frequency quenching and avoid the discharge phenomenon of sensor from melting piston rod.
