SOLIDIFICATION STUDIES T JUNCTIONS, WALLS CASTINGS
This paper aims to make a numerical and experimental analysis of the
succession of solidification zones of T-shaped intersection walls of cast
aluminium alloys. The idea of this study started with the observation that these
areas solidification thru dedicated method of cooling modules analysis does not
fully correspond to numerical analysis using a simulation solidification program.
By using the simulation software NovaCast it was studied the succession of
solidification process of T – shaped intersection of the walls of aluminium alloy
castings En AC-Al Si7Mg0,3 in several versions of ratio between the two
intersecting walls. Subsequently were made casts of this form examining their
solidification by determining the compactness of intersection and surrounding
areas. In interpreting the results obtained it can be concluded that the T-shaped
intersection of two walls, in most cases, doesn’t act as a heat node, as it would
be presumed at first glance.
