摘　　要：在实验室与生产条件下进行的判断性试验验证,工艺筋对铸件在凝固及冷却过程中的机械阻碍作用,使铸件的铸造残余应力的大小、分布发生显著的变化。合理的工艺筋可有效降低铸件的残余应力。The experiments under laboratory and production conditions have shown that process bars significantly affect the magnitude and distribution of casting residue stress through the mechanical resistance stress during the solidifying and cooling process. Process bars can effectively reduce residue stress in casting.
