反向凝固不锈钢复合带平整轧制有限元解析

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.

FEM Analysis of inversely Casting Stainless Steel Strip in the Level Rolling by ANSYS Program

Deforming physical field of inversely casting austenitic stainless steel strip during level rolling process was analyzed by ANSYS program. Plastic strain and stress of all the nodes were gained, which shows:There exists uneven deformation in the strip. Strain of the mother sheet is larger than that of the growth layer. Strain of the growth layer becomes larger from surface to inside. In the deformational zone, the stress of the growth layer is larger than that of the mother sheet. The residual stress in the strip is about 19 MPa. The rolling force estimated with ANSYS program is corresponded to those measured.
