采用消失模工艺生产薄壁壳体铸件最典型的就是球墨铸铁管件的生产,常因泡沫模样易变形而导致铸件尺寸超差和实圆变形;结合我们在生产中实践,介绍了防止泡沫模样变形和减轻铸件失圆变形的几项措施:如从模具组装、成型工艺和外加辅助手段方面进行控制,有效地减轻管件的变形缺陷。
Analysis on Preventing Ductile Iron in Lost Foam Casting from Deformation
It is typical to apply the lost foam casting to the production of ductile iron pipes. In the process, the possible deformation of foam pattern easily results in the dimension error and deformation of the castings. Based on the production practice, this paper discusses how to prevent the foam pattern and castings from deforming,and the effective measures are how to control the process of mold assembling and technology, and any possible assistant methods.
