温度变化是影响环件轧制过程的重要因素。本文考虑变形区和变形区以外两部分的不同传热特点,构造了环件连续轧制过程的温度变化有限元分析模型。该模型可用于实际生产中的工艺分析,不仅适用于环件轧制,亦适用于板带连轧等其它轧制过程。

Temperature variation is an important factor affecting ring rolling process. In the present paper, a thermal finite element model is proposed to analyze the temperature distribution in continuous multi-pass ring rolling process, while considering the different characteristics of heat transfer in deformation and non-deformation zones. The model is very useful in practical ring rolling production analysis and can find application in other rolling processes like strip and plate rolling etc.
