发动机蠕铁缸盖缩松缩孔探讨

Discussion on shrinkage porosity and cavity of Engine Vermicular Iron Cylinder Head

目前缩松缩孔问题制约发动机蠕铁缸盖的普及和推广,系统阐述了缩松缩孔在发动机缸盖易出现的部位、缩松的形态、形成原因及解决措施。

At present,the problem of shrinkage porosity and cavity restricts the popularization and promotion of engine vermicular iron cylinder heads.The positions where shrinkage porosity and shrinkage cavity are prone to appear in engine cylinder heads have been systematically expounded as well as the shape#causes of formation and solution for the shrinkage porosity.
