| 摘 要： | 在分析夹杂性裂纹形成机理的基础上,从控制锻造过程中夹杂物形状变化的角度出发,通过有限元模拟管板锻件成形过程,力求减小镦粗时的不均匀变形,提出了WHF法拔长+预镦粗+旋压成形的大型管板锻件锻造工艺。生产实践证明,采用该工艺可有效控制夹杂性裂纹的形成,提高锻件内部质量。

| Abstract: | Based on analysis of the mechanism of inclusion crack and controlling the inclusion shape,using the finite element simulation,this paper has put forward the forging process of WHF drawing out + pre-upsetting + spinning forming for heavy disc forgings.Spinning forming can reduce the non-uniform deformation in upsetting.Production practice proof that the forging process can be used to control formation of inclusion crack effectively and improve internal quality greatly. |
