The mechanical model of ring blank rolling finite element analysis was established according to the actual deformation conditions. The rolling deformation of the ring blank was numerically calculated by combining various technological factors. The law of metal flow during ring blank rolling deformation was obtained And the main process factors on the deformation characteristics of the law
