英文摘要：

The finite element model of closed rolling high-neck flange was established. And its closed rolling process was simulated by using the DEFORM-3D finite element software. The influences of initial temperature of roiled piece, the driving roll rotational speed and compressing roll feed speed on the product quality were studied by using experiment design method. The process parameters were optimized by using orthogonal test design and uniform design. The optimal parameters of rolling process were obtained.
