Thermal Observation of Casting for Aluminium Alloy at Various Moulding Sand

Manmohan Yadav, Yogesh Kumar Tembhurne

Abstract

The grain size and mechanical properties of cast metal are defined by the geometrical characteristics and thermophysical properties of the metal and the mold. Heat loss from the mold to the environment through convection can also affect the mechanical properties of cast metal. Present study reports two-dimensional numerical simulations made of aluminium alloy solidification in industrial AI 50/60 AFS greensand and mullite molds, using the finite element technique and ANSYS (version 14.5) software. FEA software like ANSYS may play an important role in predicting cast defects before the actual casting.

 

Metallurgical characteristics, such as the attack zone in the feed head and hot top were not taken into account in this study, since they are irrelevant the behaviour of heat transfer of the metal to the mold. Owing to the moulds temperature dependent thermo physical properties, this type of problem is of nonlinear characteristic.
