Summary:The invention discloses a closed forging method for improving the structure uniformity of disc forgings. The closed forging method comprises the steps that according to the specification requirements of finished forgings, a forgings blank size diagram is designed, forging equipment is selected, bars are selected as raw materials, and a closed blank manufacturing process route is designed; preparing a closed blank making mold group; according to the closed type blank making process route, a rough blank is forged and formed in the closed type blank making die set through forging equipment; and carrying out die forging on the rough blank, and carrying out die forging one-time heating to form a disc forging finished product. By means of the closed forging method, forging forming of the disc type forge piece blank is carried out in the closed die, dies of different structural shapes are selected according to the height/diameter ratio of the blank, the flaw detection level and the grain size grade of the forge piec
