摘要：

依据航空发动机钛合金、高温合金环形锻件轧制生产“控形”、“控性”的要求，建立了适用于工程应用的轧制几何简化模型，推导出环外径增速vΔD或环内径增速vΔd与内半径rt0、芯辊径向进给速度vc、主辊角速度ωm、环形锻件壁厚(Rt0-rt0)的函数关系，从而用于指导航空环形锻件轧制参数设计，实现精准设计。研究结果表明，随着rt0、vc、ωm的增加，vΔD增大；当环形锻件壁厚(Rt0-rt0)减小时，vΔD增大；对于厚壁环形锻件（法兰类环形锻件）或在环形锻件初始轧制时，应适当采用较小的环增速；对于薄壁件、大中型环形锻件或者环形锻件轧制减速阶段，需要采取控制措施来限制环增速增长过快，实现环轧过程的精确控制。

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.
