Different forging methods have different processes, among which the hot die forging process is the longest, the general order is: forging blank blanking;  Forging billet heating;  Roll forging billet preparation;  Die forging;  Trimming;  Punching;  Correction;  Intermediate inspection, inspection forgings size and surface defects;  Heat treatment of forgings to eliminate forging stress and improve metal cutting performance;  Cleaning, mainly to remove the surface oxide skin;  Correction;  Inspection, general forgings to go through the appearance and hardness inspection, important forgings also through chemical composition analysis, mechanical properties, residual stress and other tests and non-destructive testing.
