Simulation and Analysis to Reduce the Shrinkage Defect in Sand Casting for the Rotor: A Review

Abstract

Casting is a process in which the metal is melted and poured into mold and allows it to solidify to get desired shape. Objective of investigation is to review on simulation and analysis to reduce the shrinkage defect in sand casting. In ductile iron casting, shrinkage defect is common. It is generally seen at the last solidifying area of casting. Other parameters like getting system, feeder, metallurgy of material, part geometry, mold property also causes for the shrinkage defect. To remove the defect new gating system is required which is developed through analysis and with help of simulation. For that 3D CAD model is developed and analyzed in analysis software which reduce shop flower trial and reduce material waste. The design optimization of the casting system such as gating, choke, sprue, feeder, and riser pouring basin can be enhanced through a series of simulations prior to physical realization of mold and production of quality castings.
