Numerical simulation for canning extrusion process of FGH96

The configuration and dimension of the die are critical for canning extrusion of FGH96 P/M superalloy. In this paper, the influence of die angle, band length and entrance fillet of the dies on the canning integrality, extrusion ratio of the core, and extrusion force were analyzed comprehensively by using FEM and orthogonal method. The results of FEM numerical simulation and orthogonal analysis indicate that the integrality of canning and extrusion ratio of the core were improved with the decrease in die angle, band length and increase in entrance fillet of the die. The optimal combination of the structural parameters of the extrusion die was obtained.
