为精明的温度变化的 A coupled thermo 机械的模型包含金属流动和温度地被开发了在上十四通行证用 3D 的为 Inconel 718 合金的圆杆的热连续滚动有弹性塑料的有限元素方法(女性) 。在细工品的中间的剖面图的典型分析点的温度在起始的温度变化被模仿了在圆柱的热压缩实验的 nite 元素分析和微结构观察,适当热连续滚动技术与不同直径为杆产品被设计了。为一个真实滚动惯例,模仿的表面温度被检验并且在对测量的那的好同意。
A coupled thermo-mechanical model containing metal flow and temperature field for calculating temperature variation has been developed on fourteen-pass hot continuous rolling of round rod for Inconel 718 alloy using 3D elastic-plastic finite element method (FEM). The temperature of characteristic analysis points in the intermediate cross-section of the workpiece has been simulated at initial temperature ranging from 960 to 1000 ℃ and initial velocity in range of 0.15-0.55 m·s^-1. Based on finite element analysis and microstructural observation in cylindrical hot compression experiments, the appropriate hot continuous rolling technologies have been designed for rod products with different diameters. For a real rolling practice, the simulated surface temperature was examined and is in good agreement with the measured one.
