Abstract (en)
[origin: WO2011061444A2] The method for manufacturing the metal part (10) from a hollow ingot (10A) includes: axially stretching (100) the hollow ingot (10A) by means of forging; horning (120) the stretched ingot (10B) on the forging press (12) in order to form a generally tubular intermediate preform (10C); rolling (130) the intermediate preform (10C) on a circular rolling mill (16), thus enabling formation of a blank (10D); and machining (140) the blank (10D) so as to provide it with the size and shape of the finished metal part (10).
