The invention relates to a method for improving the flaw detection qualification rate of an aluminum alloy ring piece finished product, which comprises the following steps: flaw detection is carried out after the surface of a forged ring blank is exposed to light to obtain a first threshold value and a second threshold value of a flaw detection unqualified area; obtaining a first outer diameter, a first inner diameter and a first height dimension; if the first inner diameter is larger than the first threshold value, it is judged that flaw detection of the ring piece finished product is qualified; if the first inner diameter is smaller than or equal to the first threshold value, it is judged that flaw detection of the ring piece finished product is unqualified, and a flaw detection unqualified area is reversely deduced and checked; and the forging process parameters are adjusted again, new forging process parameters are obtained, and the third threshold value of the adjusted flaw detection ...

The invention claims a triple-double method forging new process of 6-meter level aluminum alloy forged ring hydraulic press, the preparing process comprising steps of: (1) blanking aluminum alloy ringon a 6000T hydraulic press first and chambering radially by using a trestle; (2) then processing axial deformation on a 30000T hydraulic press so that the ring extends radially, diameter of which reaches 6 meters finally. The process of the invention is not limited by headway of the hydraulic press and width of worktable and can produce aluminum alloy forged ring with outer diameter 6 meters by using prior 6000T and 300000T hydraulic presses combined; the process is simple and convenient to operate, high in efficiency, work procedure reduced by 30% than that of rolling procedure. The two blanks deform together, which does not only maintain balance of the hydraulic press, but also improve production efficiency; deformation of one time is huge, which reduces folding and has good performanceof ...
