Abstract: In view of the construction feature of shell body blank made by 30CrMnSiNi2A and the
specificproperty of material ,the experiments are performed to investigate the warm extrusion of shell
body blank;and theoptimized designof major processparameters arefinished by meansof ”experimental2
orthogonal method”。The experimented results show that the forging of shell body manufactured by
warm extrusion fulfil quality requirements,and each of property target is up to standard。
