Macrosegregation Prediction
Prediction of Macrosegregation Formation for Continuous Casting of Ternary
Bronze Alloys.
Calculated Temperature of Continuous Casting Strand
This project is aimed at modeling the macrosegeration
formation during continous casting of bronze.
The CFD software FLUENT was used in combination
with UDF. The solidification of the strand as well as
the formation of macrosegeration were simulated
with a two phase volume averaging model. Phenomena
to be considered include heat transfer,
solute transport, fluid flow, and solid movement at
macroscopic scale of the casting, as well as phase
equilibrium, structure formation, segregation, and
flow at various microscopic scales.

Macrosegregation refers to variations in composition
that occur in alloy castings or ingots and range in
scale from several millimeters to centimeters or even
meters. These compositional variations have a detrimental
impact on the subsequent processing behavior
and properties of cast materials and can lead to
rejection of cast components or processed products.
Because of the low diffusivity of the solutes in the
solid state and the large distances involved, macrosegregation
cannot be mitigated through processing
of the casting after solidification is complete.
