Analysis of the Thermal State of a Semifinished Product During Hot Die Forging

Resumo

Results are presented from the use of numerical modeling to perform an empirical assessment of the effect of the initial process parameters in hot die forging (the temperatures to which the deforming tools and semifinished product are heated) on the temperature field in the semifinished product during deformation. A series of numerical experiments is performed on the basis of the finite-elements method, the resulting data are analyzed, and relationships between the parameters are established and explained.
