Analysis of Casting Defects in Foundry by Computerised Simulations (CAE) - A New Approach along with Some Industrial Case Studies

摘要

This study reports an in house experience of the occurrence of different types of casting defects and its scientific analysis by computerised simulation techniques supported by industrial case studies. The main two categories of defects viz. solidification related defects like hot tear, shrinkage and porosity defects etc. and flow-related defects like sand burn in and rough surface/metal penetration, air entrapment, cold shut etc. are discussed here along with simulation results and practical case studies.
