800 MN模锻压机用大拉杆热处理调质研究

Study on Quenching and Tempering Heat Treatment of Large Pull Rod for 800 MN Die Forging Press

800 MN模锻压机用大拉杆的调质淬火超过了公司现有水槽和油槽的淬火能力。通过改变热处理淬火工艺,突破了淬火设备的限制,避免了大拉杆的淬裂风险,同时力学性能也一次性合格。

The quenching process for the large pull rod used in the 800 MN die forging press exceeds the quenching capacity of the existing water tank and oil tank of the company.By changing the heat treatment quenching process,the limitation of quenching equipment has been broken,and the risk of cracking of large rod has been avoided.Meanwhile,the mechanical properties have been qualified in one time.
