利用通用有限元软件Marc/Mentat,采用二维弹塑性大变形有限元法,对粗轧过程中各道次温度场进行了数值模拟,分析了轧制过程中轧件温度场的分布和变化规律,并与实际结果进行比较,从而验证了计算结果的准确性.研究表明,轧件变形中,接触热传导和变形传热是影响温度变化的两个主要因素,二者的综合作用决定了轧件各点的温度变化规律,可以为指导实际工作提供相应的理论依据.图3,表1,参11. The common finite element software Marc / Mentat was used to simulate the temperature field during the rough rolling by using the two-dimensional elasto-plastic large deformation finite element method. The distribution and variation of the temperature field during the rolling process were analyzed , And compared with the actual results to verify the accuracy of the calculation results.Research shows that the rolling deformation, the contact heat transfer and deformation heat transfer are the two main factors that affect the temperature changes, the combined effect of the two determines the rolling The temperature variation of each point can provide the corresponding theoretical basis for guiding the actual work.Figure 3, Table 1, reference 11.
