Review of Sand Inclusion Defect Analysis to Initiate the Improvement in FNB Casting Process
Abstract: Sand inclusion is an important defect in grey cast iron castings. On an average, this defect accounts for 30 to 40% of the total number of defects arising in the foundries. Sand inclusion is undesirable since it ends up in reducing the strength of the castings and worsens the finish of the casting surface. Hundred or more parameters are responsible for sand inclusion defect and hence it is cumbersome and …
