Abstract

Aluminum alloys are widely used in the production of aerospace, aircraft, and automotive components. The die casting components are subjected to post-processing operations, such as milling and turning operations to get final shape, surface finish, and dimensional tolerances. During machining operations large quantities of material are removed from the cast components in the form of chips to achieve final shape and size. The chips that are produced during machining operations are mixed with oils, lubricants. This article discusses how effectively the aluminum can be recovered from the chips with maximum metal recovery and minimum melting loss without compromising quality and chemical composition. The different types of techniques are employed, and their results are discussed in this paper. Al-Si8Cu3Fe (LM24) alloy is selected for investigation purposes. The recovery techniques, such as with flux, without flux, with different melting furnaces, with different melting temperatures, with or without compacting, are studied.
