Forging method for efficiently healing hole flaws inside blank with large height-diameter ratio

The invention belongs to the field of forging, and specifically relates to a forging method with a small screw-down rate, which is capable of efficiently healing hole flaws inside a blank with a height-diameter ratio. The forging method adopts a numerical simulation technique to research the distribution status of strain inside the blank in the conventional forging process, thus providing a radial wide anvil compaction process which comprises the following steps of: pressing down the blank by virtue of the radial wide anvil compaction process, wherein flat plates serve as upper and lower anvil; after radial the wide anvil compaction process, returning the blank to a furnace to be re-heated and be subjected to thermal insulation; and turning over the blank by 90 degrees and drawing out the blank by the upper and lower anvil. The forging method is suitable for a free forging process for various blanks (for example continuous-casting blanks) or steel ingots with a large height-diameter ratio and the like, and particularly has good effects on the blank with the large height-diameter ratio and serious centre looseness. Forged pieces produced by the forging method can ensure the healing of the hole flaws inside the blank with the large height-diameter ratio, so that the possibility of forged piece scrapping caused by the loosened and non-forged center of the forged piece is greatly reduced; and moreover, a forged piece with a larger size can be manufactured by virtue of a small screw-down rate.
