| Abstract Scope |
An orthogonal array was designed based on four factors and three levels were chosen. Recovery rate and corrosion resistance were selected as two individual responses to evaluate the effectiveness of the recycling process and the quality of recycled alloy A380. Two sets of weighing factors were selected for the responses of recovery rate and corrosion resistance, respectively, for different requirements of the recycled alloy. The optimum combinations led to the highest recovery rate by using Al-clean 101 as the refining flux, 10:5 as the chips/flux ratio, 60 minutes as the holding time and 760℃ as the holding temperature, while the combination of using Al-clean 113 as the refining flux, 10:3 as the chips/flux ratio, 90 minutes as the holding time and 800℃ as the holding temperature made the recycling process effective considering both the recovery rate and corrosion resistance. |
