The analysis of solidification in cast iron projects using MAGMASOFT® is performed through a series of results.
The Fraction Liquid, Hot Spot and Porosity results should always be used for better understanding of the solidification process. These results allows us to understand how solidification develops, identifying the moment when the feeding zones are separated and also identifying regions where there is liquid mass isolation, in the casting, during solidification.
MAGMASOFT® also allows the identification of the origin of a shrinkage porosity, that is, if it is primary (from the contraction of the metal during solidification) or secondary (due to the inability of the graphitic expansion to feed some product's regions). With this analysis, it is possible to devise appropriate strategies to solve both cases.
This evaluation relies on the progressive result of Porosity, which shows not only the moment of the appearance of shrinkage porosity, but also those that are compensated by the formation of graphite.
If the fraction liquid in the moment of porosity formation is high, we can conclude that the porosity is primary. Likewise, if the fraction liquid is low, we have a secondary porosity.
