According to the requirements of “shape control” and “property control” in the rolling production of titanium alloy and superalloy ring forgings for aero engine, and a simplified rolling geometry model suitable for the engineering application was established, and the function relationship between ring outer diameter growth rate vΔD or ring inner diameter growth rate vΔd and inner radius rt0, core roller radial feeding speed vc, main roller angular velocity ωm and wall thickness (Rt0-rt0)  of ring forgings were derived to guide the design of rolling parameters for aviation ring forgings and realize the accurate design. The results show that with the increasing of rt0, vc or ωm, vΔD increases. When the wall thickness (Rt0-rt0) of ring forgings decreases, vΔD increases. However, for thick-walled ring forgings (flange ring forgings) or ring forgings during the initial rolling, a smaller ring growth rate is appropriately adopted, and for thin-walled parts, large and medium-sized ring parts or ring forgings during the rolling deceleration stage, the control measures need to be taken to limit the ring growth rate from growing too fast and achieve the precise control of the ring rolling process.
