通过对高温气冷堆压力容器封头外形特点进行分析,提出了"预制板坯+冲压"的成形方案.通过对高温气冷堆压力容器封头锻件板坯制造和板坯冲压工艺方案进行研究,获得了整体长砧过中心镦剥的板坯控圆成形工艺和大直径板坯大位移小变形冲压成形工艺.通过工程实践,验证了高温气冷堆压力容器封头的近净成形方案合理可行.
Research on Near Net Forming Technology for Pressure Vessel Head of High-temperature Gas-cooled Reactor
By analyzing the external characteristics of the pressure vessel head of high-temperature gas-cooled reactors,a forming scheme of"prefabricated slab + punching"was proposed.Through the study of slab manufacturing and punching processes for pressure vessel head forgings of high-temperature gas-cooled reactors,the controlled-circle forming process of slab with integral long anvil over-center upsetting and stripping and the large diameter slab with large displacement and small deformation punching forming process were achieved.After engineering practice,it has been verified that the near net forming scheme for the pressure vessel head of high-temperature gas-cooled reactors is reasonable and feasible.
