Title
(EN) Method for predicting and preventing shrinkage cavity of iron casting
(ZH) 铸铁铸件的缩孔的预测及防止方法
Abstract
(EN) A method for predicting and preventing occurrence of shrinkage cavity in an iron casting of any of various shapes or in each part of an iron casting precisely prior to casting. The shape of an iron casting is approximated entirely or partially to a rectangular parallelepiped or a cube, to the sum of the two long sides is divided by the short side to determine a shape coefficient, and occurrence of shrinkage cavity is predicted by judging whether the value exceeds a predetermined value (judgment coefficient) or not.
(ZH)

本发明提供一种对于各种形状的铸件或铸件的各部分,在铸造前高精度地预测有无缩孔发生并予以防止的方法。将铸件产品的形状整体地或部分地近似成长方体或立方体,求出将较长的两个边的合计值除以剩余的较短的一个边得到的值、即形状系数,通过该值是否超过规定值(判定系数)来预测缩孔的发生。
