摘要
对汽车连杆滚锻模表层的工作温度进行了理论分析，并采用金相硬度法进行了估算，两种结果均表明滚锻模工作时表面温度在400-600℃范围内。
The theoretic analysis for surface working temperature of roll forging die for automotive connecting rod is conducted.Estimation is performed by using metallographic hardness method, both results indicate that the surface working temperature of roll forging die is within 400-60℃
