Different forging methods have different processes, wherein the hot forging process has the longest process, and the general sequence is: forging blanking; forging billet heating; roll forging stock; die forging; trimming; punching; Intermediate inspection, inspection of the dimensions and surface defects of forgings; forging heat treatment, to eliminate forging stress, improve metal cutting performance; cleaning, mainly to remove surface oxide scale; correction; inspection, general forgings to pass the appearance and hardness inspection, important forgings It is subject to chemical composition analysis, mechanical properties, residual stress and other tests and non-destructive testing.
