The new feeding model is available for all types of cast iron: Grey, ductile and compacted graphite iron. Thus, both metal quality and inoculation state influence feeding and shrinkage formation in the casting. The software calculates local metal transport in partially solidified regions of the casting and the resulting ability to feed the solidifying iron. Pressure differences in the metal are created through the combination of metallostatic pressure, local austenite shrinkage and graphite precipitation and the rigidity of the mold. The “heart” of the optimized MAGMAIron module is the SMAFEE feeding algorithm. The impact of the flow on the resulting temperature profile influences the feeding behavior both, large castings and in series production. In addition, thermal convection during solidification is now calculated as a standard for iron castings. With the innovative SMAFEE feeding algorithm, the influence of melt quality, inoculation practice and local pressure distributions on porosity development is even better taken into account. Completely new capabilities are available to iron foundrymen to consider the effects of metallurgy and metal treatment on solidification and feeding behavior.
