利用ＡＮＳＹＳ有限元分析软件对反向凝固不锈钢复合带的平整轧制过程进行了变形 物理场分析，得出了复合带平整轧制时内部各点的塑性应变和应力分布：轧件内存在不均匀变 形，母带的应变大于凝固层，凝固层应变从表面向内部逐渐增大；在轧制变形区内，凝固层的应 力大于母带；轧件的残余应力约为 １９ ＭＰａ．轧制力的解析结果与实测的轧制力基本相符．
The finite element analysis software ANSYS was used to analyze the deformation physical field of the flattening process of the reverse solidified stainless steel composite strip. The plastic strain and stress distribution at each point during the smooth rolling of the composite strip were obtained: In the deformation zone, the strain of the masterbatch is larger than that of the solidified layer, and the strain of the solidified layer gradually increases from the surface to the inside. In the deformed area of rolling, the stress of the solidified layer is larger than that of the masterbatch. The residual stress of the rolled material is about 19 MPa. Analysis of the rolling force results and measured the rolling force is basically consistent.
