摘要
借助Marc商用软件 ,采用弹塑性大变形热力耦合有限元法 ,对薄板坯CSP生产线Q2 35钢 15 0 4mm× 4 2mm轧件第 2道次的热轧过程进行轧件温度场分布以及轧制力能参数变化的模拟和分析。结果表明 ,从轧件入口到轧件出口 ,沿轧制方向等效应变逐渐增大 ,最大值为 0 5 7;模拟得到的轧制力为 2 3380kN ,现场轧机记录轧制力为 2 35 37kN ,预测误差为 0 6 7% ,所采用的有限元模拟方法能较好地反映金属的实际变形。
The simulation and analysis of temperature field distribution and rolling force parameters of steel Q235 1 504 mm×42 mm rolling slab in secondary pass hot rolling process in compact strip production (CSP) line have been carried out using thermo-mechanical coupling elastoplastic finite element method (FEM) by Marc commercial software. The results showed that from slab at rolling inlet to slab at rolling outlet the equivalent strain of rolling slab increased gradually along rolling direction and the maximum value was 0.57; as the rolling force obtained by simulation was 23 380 kN and the rolling force measured at mill situ was 23 537 kN, therefore the predict error was 0.67%. It is clear that the used FEM can better reflect real deformation of metal.
