Determination of the Magnitude of Interfacial Air-gap and Heat Transfer during Ingot Casting into Permanent Metal Moulds by Numerical and Experimental Techniques

Abstract:

Numerically and experimentally the size of the casting-mould air-gap was investigated for the aluminium alloy LM25 cast into a cylindrical H13 steel mould. The air-gap significantly affects the magnitude of heat transfer. A numerical model has been developed to predict the size of the air-gap and the temperature distribution along the metal-mould interface given an initial Interfacial Heat Transfer Coefficient (IHTC), dependent on the mould surface roughness, and sufficient knowledge of the r...
