【摘要】 针对30CrMnSiNi2A超高强度钢制壳体毛坯的结构特点和材料工艺特性,对该壳体毛坯的温挤压成形工艺进行了大量的试验研究;并采用"正交试验方法"对温挤压工艺参数进行了优化设计。经过理化检测和使用结果表明,采用温挤压工艺生产的30CrMnSiNi2A钢制壳体毛坯锻件完全满足壳体的使用要求,各项性能指标合格。更多还原

【Abstract】 In view of the construction feature of shell body blank made by 30CrMnSiNi2A and the specific property of material,the experiments are performed to investigate the warm extrusion of shell body blank;and the optimized design of major process parameters are finished by means of "experimental-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?更多还原
