The basic technological process of hot ring forging is shown in the figure. Taking 42CrM0 material as an example, the cylindrical blank is heated to about 1150â?? for upsetting, punching and de-peeling to get the ring blank, and then the ring blank is put into the radial axial ring rolling machine for milking until the size requirements are met.
