摘要：

为满足航空环形锻件批量制造过程稳定性及制造产品质量一致性的要求，同时为了满足轧制过程精细化设计及产品自动轧制生产的需要，根据航空环形锻件轧制生产控制特点及实际生产经验，将芯辊径向进给曲线规划为5段折线的进给曲线，构建了径向轧制进给位移方程组{ΔH=f(vi,Δti)、ΔH=f(D0,d0,D1,d1)}，提供了每段轧制时间Δti以及初始进给速度vi的工程经验值，从而求解出芯辊径向进给曲线vi=f(Δti)，并按照轧制理论和航空材料轧制特性，对初始轧制速度v1、环件外径长大速度vΔD进行了校核，最终完成了环轧过程的精细化设计，从而满足了航空环形锻件工艺特性、制造特点、质量要求、自动化轧制参数的需要。

In order to meet the requirements of stability in batch manufacturing process for aviation ring forgings and the quality consistency of manufactured products, and also to meet the needs of refined design for rolling process and automatic rolling production for products, according to the rolling production control characteristics and actual production experience of aviation ring forgings, the radial feeding curve of mandrel was planned as a feeding curve with five segments, and the feeding displacement equation group {ΔH=f(vi,Δti ),ΔH=f(D0,d0,D1,d1)} in the radial rolling were built. Then, the engineering experience values of rolling time Δti and initial feeding speed vi of each stage were provided, and the mandrel radial feeding curve vi=f(Δti) was solved. Furthermore, according to the rolling theory and rolling characteristics of aviation material, the initial rolling speed v1 and the growth speed of outer diameter for ring vΔD were checked, and the refine design of ring rolling process was finally completed to meet the needs of process characteristics, manufacturing characteristics, quality requirements and automatic rolling parameters for aviation ring forgings.
