Steel Casting Optimization of a Gas Diffuser
An optimal gating and feeding system for the production of steel parts
The object of this study is a steel diffuser, which for obvious reasons needs to comply with very strict quality guidelines and industry regulations.
The main type of defect that could be expected when casting this workpiece is shrinkage porosity.
Shrinkage porosity tends to occur at the top of hot spots due to the fact that molten steel is not as dense as the solidified and cooled down steel.
It is therefore of paramount importance to design an optimal gating and feeding system for the production of steel parts such as this diffuser.
The MAGMASteel and MAGMAFrontier modules from MAGMASoft were used to carry out around 200 simulations.
The results were carefully analyzed to find the minimum optimal number and optimal position of feeders and chills to be used in the casting process, with the aim of attaining a finished workpiece free of shrinkage porosity.
