Quality Assurance of Cylindrical Casted Parts with Small Thickness

Résumé

The casting of the cylindrical parts with great diameter and small thickness and intermediary flange is difficult because of the great values of the forced contraction. Thus the value of the tensile stress is very great and can determine the fracture of the part in zone of the thermal knot. For assurance of the quality of these parts some technological solutions are necessary. The paper shows the analysis of this aspect and presents practical solutions.
