为了解决高韧度薄壁球铁铸件承压套容易产生缩孔缩松缺陷、生产品质不稳定的问题,利用Pro Cast软件做计算机模拟实验,设计浇冒系统,经过生产验证和无损检测,铸件缩孔缩松缺陷消除,内在品质和力学性能达到标准要求。 In order to solve the problem of shrinkage shrinkage defects and instability of production quality in high-strength thin-walled ductile iron castings, the Pro Cast software was used to simulate the design of the cast-in-place system. After production verification and nondestructive testing, Shrinkage defects eliminated, the inherent quality and mechanical properties to meet the standard requirements.
