| Abstract: | he rolling deformation characteristics for ring with stepped hole are analysed and the ring diameter in rolling is derived. The axial volume flow occured in rolling process of ring with stepped hole is demonstrated, the calculation formula of the volume flow amount is derived and the feed condition matched to the volume now is pointed out. The blank design principle and method for rolling ring with stepped hole is developed based on the volume flow law and the comparison to the ring rolling experiment is done. |
