采用热力耦合刚塑性有限元法对平板精轧机组的非稳态轧制过程进行了仿真,并将仿真结果与实际生产数据进行了比较,结果表明所采用的方法对非稳态轧制过程进行仿真是可行并且可靠的。在此基础上,分析了轧制温度、前后张力等工艺参数对非稳态轧制过程的影响规律,提出了缩短板带头部厚度不考核长度的措施。 The unsteady rolling process of the plate finisher was simulated by the method of thermo-coupled rigid-plastic finite element method, and the simulation results were compared with the actual production data. The results show that the method adopted for unsteady rolling process Simulation is feasible and reliable. On this basis, the influences of rolling temperature, ante-tension and other process parameters on the unsteady rolling process were analyzed, and measures to shorten the thickness of the head of the strip without checking the length were proposed.
