摘　　要：采用MSC .Marc三维热力耦合弹塑性大变形有限元软件及其接触分析技术 ,在分析现场工艺设备参数建立相关边界条件的基础上 ,对Φ15 3mm合金钢 4道次热连轧过程中轧件变形进行了三维模拟仿真 ,计算了轧件的应力、应变、温度分布和轧制力、轧制力矩的分布。The four\|pass hot continuous rolling of Φ153 mm alloy mandrel steel has been simulated and analyzed by the three dimensional thermal mechanically coupled elastoplastic finite element method (FEM) software package - MSC.Marc based on the foundation of established relative boundary conditions by analyzed process and equipment parameters in situ. And the distribution of stress, strain and temperature of billet as well as the distribution of rolling force and torque are calculated.
