Finite-Element Analysis on the Rolling Process of Semi-solid Steel in Different Roll Shapes

  • 摘要: 采用多孔材料的几何模型,利用MARC有限元软件对弹簧钢60Si2Mn半固态轧制过程进行了三维有限元模拟,分析了在平辊和孔型轧制条件下的应力、应变场.在孔型中轧制,轧件变形区横截面上应力、应变场分布均匀.模拟结果与实验结果相吻合,说明半固态材料适合在孔型中轧制.

     

    Abstract: With a geometrical model of porous materials, 3D finite-element analysis on the rolling process of 60Si2Mn in the semi-solid state was carried out using the software MARC. In terms of flat and groove rolling conditions, the stress field and strain field were studied. During groove rolling, the distributions of stress and strain on the cross-section of the deformation zone was more uniform than those during flat rolling. Simulation results were good agreement with experiment data, and showed that semi-solid material was suitable for groove rolling.
