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.
