Thermal Analysis for Shrinkage Prediction in Commercial Ductile Iron Castings

Pages 251-260 | Published online: 18 Jul 2013
 

Abstract

Results from two complementary projects concerning shrinkage prediction in ductile iron castings are integrated: the first, a statistical approach to predictive modeling for process control using plant data; and the second, the development of a finite element model of ductile iron solidification. Each project is a distinct application of thermal analysis. Our integrated approach to the shrinkage problem provides a direct link between computer-aided design based on numerical simulation, and process control in the foundry based on thermal analysis.

Résumé

Cet article intègre les résultats de deux projets complémentaires sur la prédiction des contractions dans les fontes ductiles. Le premier est une approche statistique servant à modéliser de facon prévisionnaire le contrôle de procédé en utilisant les données de l'usine. Le second est le développement par analyse des éléments finis, d'un modèle de solidification des fontes ductiles. Chaque projet est une application particuliére de l'analyse thermique. Notre approche intégrée au probléme de contraction permet d'effectuer un lien direct entre le design assisté par ordinateur, basé sur des simulations numériques, et le contrôle de procédé dans la fonderie, basé sur l'analyse thermique.
