Method for Predicting and Preventing Shrinkage Cavity of Iron Casting |
摘要 |
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 determining whether the value exceeds a predetermined value (determination coefficient) or not.
