Simulation and Technology Optimization for Large Backup Roll Forging Process
The mechanical and thermodynamic properties of 45Cr4NiMoV material for large forging backup roll were mensurated by Gleeble-1500D thermal simulation testing machine.At the same time,DEFORM-3D software was used to simulate the two main processes,upsetting and stretching,the temperature field,stress field and strain field under the conditions of different anvil width ratioes in the forging process were analyzed,so the forging technology program was optimized.
