Document Type and Number:
WIPO Patent Application WO/2010/026779
Kind Code:
A1
Abstract:
Provided are a method for producing a wheel having an excellent and uniform mechanical strength, and a wheel. The method for producing a wheel comprises a preparation step (S1) for preparing a molten material by melting a light metal alloy, a casting step (S2) for producing a cast billet by casting the molten material, a preliminary forging step (S3) for producing a forged billet (2) by performing pressure compression of the cast billet (1) so that the forging ratio becomes 3.5 or more, a main forging step (S4) for producing pre-wheels (3a, 3b) by performing pressure forging of the forged billet (2) using a die, a heat treatment step (S5) for heat treating the pre-wheels, and a forming step (S6) for processing the pre-wheels (3a, 3b) mechanically.
