Recovery of Aluminum Alloy A380 from Machining Chips

Die casting aluminum alloy A380 were recoveredfrom high pressure die cast machining chipsunder a series of designed experiments using Taguchi Method, where flux types (FT), chips/flux ratio (CFR), holding times (Ht) and temperatures (HT) were selected as four factors. For each factor, three levels were chosen to create Taguchi orthogonal array. The recovery rate (Rr) was selected as a response to evaluate the effectiveness of the recovery process. An analysis of the mean of noise-to-signal (S/N) ratios indicates that the recovery rate is affected considerably by the levels in the Taguchi orthogonal array. The optimum combination leads to the highest recovery rate of 92.03% by using Al-clean 101 as the refining flux, 10:5 as the chips/flux ratio, 60 minutes and 760°Cas the holding time and holding temperature.
