摘要: 采用三维大变形热力耦合弹塑性有限元法,借助商业有限元软件MSC.Marc,建立了辽宁特钢 304不锈钢棒线材18道次连轧过程的三维数学模型。采用3组连续模型模拟了该过程,道次出口处采用刚性 面控制轧件前进,各模型之间的数据通过插值方式传递,得出304不锈钢轧件同一截面上心部、中部和表面点 从出炉到18道次轧制过程的温降曲线。计算结果与实测值吻合,误差为5~50℃.

Abstract: The three dimensional mathematic models of 18- pass continuous hot rolling for 304 stainless steel tod and wire have been established using three dimensional thermomechanical coupled elastic- plastic finite element method (FEM) by commercial finite element software MSC.Marc. The process is simulated using three continuous models, a rigid surface at end of each rolling pass is employed to make the workpiece run, and the data between each two model are transferred by interpolation to get temperature fall curves at center, medium and surface of same section of 304 stainless steel workpiece during the process from outlet of heating furnace to end of 18th pass rolling.The results showed that the calculated value coincides with measured value with error 5~50℃.
