Abstract
The study deals with the casting defects of shrinkage and dispersed shrinkage appeared during the development of ductile iron bearing seat due to the original process of conventional side-riser feeding on the basis of general casting design method. The bearing seat was cast using automatic air-impact moulding production line with green-sand. The commercial software of InteCAST was used to simulate casting solidification process and to analyse the reason for the casting defects. Further, the optimised process was proposed in conjunction with three pieces of arc-type chills and a side-rider every casting. The result of mass production shows that the casting defects of bearing seat were effectively eliminated by the optimised process. Consequently, the development cycle of bearing seat was significantly shortened and business opportunities of new market are obtained for the foundry enterprise.
期刊介绍:
IJCMSSE is a refereed international journal that aims to provide a blend of theoretical and applied study of computational materials science and surface engineering. The scope of IJCMSSE original scientific papers that describe computer methods of modelling, simulation, and prediction for designing materials and structures at all length scales. The Editors-in-Chief of IJCMSSE encourage the submission of fundamental and interdisciplinary contributions on materials science and engineering, surface engineering and computational methods of modelling, simulation, and prediction. Papers published in IJCMSSE involve the solution of current problems, in which it is necessary to apply computational materials science and surface engineering methods for solving relevant engineering problems.
