Study on Extrusion Forming of Superalloy Tube under Different Dies

Abstract:

Extrusion die is a key factor in tube extrusion deformation. This paper, studying Inconel 690 alloy steel tube hot extrusion process by adopting Deform-2D software, analyses the influence of flat dies, cone die and flat-cone die on extrusion force, temperature rise, and metal flow rule during superalloy extrusion process and find that cone die is more helpful for superalloy tube extrusion. Based on it, the influence rule of cone die angle on extrusion force and temperature rise is studied, and the best die angle for superalloy tube extrusion is provided, which offer the evidence for the design of superalloy tube extrusion die
