Improvement of quality of a gravity die casting made from aluminum bronze be application of numerical simulation

By A. Fajkiel, P. Dudek, W. Walczak and P. Zawadzki

Abstract

The paper describes the possibility of improving the quality of gravity die cast connectors for overhead power transmission lines. The castings were made from aluminum bronze, grade CuAl9Fe1Ni1. A MAGMAsoft computer programme was used for simulation of the process of die filling and casting solidification to avoid defects, like shrinkage depression and gas porosities. The results of the simulation have finally led to redesigning of the metal feeding and cooling system and to reduced level of defects in castings
