Finite Element Analysis of Rolling Process for Pilger Mill

For the simulation of cold rolled 20Cr steel pipe rolling process the DEFORM-3D being used, the simulation results include the equivalent stress, equivalent strain and rolling force distribution in deformation zone. The stress state of the pipe reducer section is analyzed, analysis shows that the simulation result is approximate the theoretical calculation. The simulation result shows the roll pass and openning effect on the rolling pipe. A view put forward is to compare the simulation results with the actual production and find out their differences. A proposal is made to establish a corresponding database based on simulation and production data.
