<p>Disclosed herein is an apparatus and method for forming a product having an asymmetric cross-section using a ring rolling process. The method of forming a product having an asymmetric cross-section uses a ring rolling process that uses a ring rolling apparatus, the ring rolling apparatus comprising: a main roll pressing a circumferential outer surface of a blank (8), a pressure roll (6)pressing a circumferential inner surface of the blank (8), and a pair of axial rolls pressing upper and lower surfaces of the blank (8), wherein a protrusion (6a) provided on the pressure roll (6) comes into contact with a depressed portion formed on the circumferential inner surface of the blank, and as a width of the blank varies, the pressure roll (6) moves in a vertical direction.</p> |
