Research on and Application of Forging Process for Special-shaped Forgings of Iron-Nickel-based Alloy
The special-shaped forgings of iron-nickel-based alloy involved in this paper have special shapes and complex structures,which make the forming process difficult.This paper aims to study the forging process of special-shaped parts by means of the existing production technology conditions in the workshop and adopting the free forging method.The DEFORM numerical simulation software is used to make the simulation calculation for the main forming process and simulate the forming effect of special-shaped parts with the free forging method.Through the analysis of material flow,stress and strain distribution,temperature variation and forming quality of forgings during the forging process,the forging process parameters are optimized and the forming quality of forgings is improved.Through actual production verification,the forming effect of special-shaped forgings is good,and the formed shape is highly consistent with the numerical simulation results,which verifies the correctness of the numerical simulation results and proves the rationality and feasibility of the free forging process for special-shaped forgings of iron-nickel-based alloy.
