Large ingots tend to have internal defects such as shrinkage cavities and porosities, which have to be closed during the cogging stage to ensure sound internal quality of forged parts. In this work, finite element methods were used to simulate open die forging passes, with varying parameters that affect the void closure behavior profoundly. Numerical models ware constructed in FORGE using practical forging parameters and material rheological data obtained from the Gleeble compression tests. Forging variables such as die overlap, reduction amount and die width were studied with intense attention paid on the special properties of H13 steel, so that this study can be applied to solve real world problem.
