解决薄壁大平面铸件铸造缺陷的几种方法

摘要

The main casting defect in thin-wall big plane casting is choking air hole and bubble. The defect led by choking air hole reached 70 per cent. This kind of defect has caused great impact on casting quality, production efficiency and production cost. Several methods to solve the defect of choking air hole in thin-wall big plane casting,such as pouring temperature,core outgassing and pouring system have been introduced.%呛气孔是薄壁大平面铸件的常见铸造缺陷，薄壁大平面铸件呛气孔缺陷率达到70%，这种缺陷在很大程度上影响铸件质量、生产效率和生产成本。介绍几种解决大平面呛气孔铸造缺陷的方法。
