摘　　要：本文采用铅作为模拟材料，对热带粗轧机组平辊立轧变形规律进行了实验研究，得到了表征立轧稳定轧制阶段时轧件断面特征的四个参量与侧压量、立辊直径、板坯来料厚度及宽度之间的关系。并首次提出用超薄单元近似处理奇异点的新方法，采用全三维刚塑性可压缩有限元法对立轧稳态过程进行了理论解析，所得结果和实验结果符合较好。In this paper,a model material,pb,was used to simulate edge rolling.Four parameters which characterized the cross-sectional profile of dog-bone during steady deformation were analyzed as a function of initial slab thickness and inital slab width,width reduction and edger roll diameter.An simulation to this process was developed with 3 D Rigid Plastic FEM,the results were in good agreement with the experimental ones.Moreover,a new approach that one very thin array of element was attached before the entry of roll to deal with singular point was present,in which the program was simplified.
