摘　　要：热轧大型H型钢是典型的非线性塑性大变形过程,由于现场轧制条件的限制,轧件及轧辊的内部信息很难实现即时提取。本文基于有限元软件ABAQUS,以自定制应用程序的方式开发了大型H型钢热轧过程的仿真系统,通过参数化输入,实现了前处理建模、任务提交分析以及结果信息提取等整个分析流程的自动化,该系统可模拟轧制过程中弹性轧辊及轧件内部的应力、应变、温度场和金属流动等结果。以HN900×300型钢的轧制为例,验证了系统的正确性及可靠性。The hot rolling of large H-beam is a highly non-linear plastic deformation process, and the real-time detection of internal information for H-beam in rolled process can not be executed because of the hot environment. The finite ele- ment simulation system for large H-beam hot rolling was developed based on ABAQUS and coupled thermal elastic- plastic finite element method by customizing applications and embedding re-meshing algorithm and subroutines, which automatically achieved modeling in pre-processing and extracting simulation results in post-processing, improved the ef- ficiency of optimizing hot rolled parameters and shorten the development cycle of developing new H-beam. The simula- tion system was verified through comparing the temperature field in hot rolled process of HN900 X 300 between simula- tion results and field data collected by infrared thermometer.
