Abstract : The present work submits an investigation about the optimum process parameters and quality improvement of mill scale recycling.
With increasing concerns on environmental issues, the recycling of materials of all types has become an important issue. In this paper, an
optimization method is developed to improve quality in mill scale recycling. The optimum configuration of process parameters to
achieve high metallization efficiency was determined by experiments. The Taguchi method, the signal-to-noise (S/N) ratio, the analysis
of variance (ANOVA) and rsponse surface optimization are employed to find the main effects and to determine their optimum process
parameters. The significant process parameters were identified and their effects on mill scale recycling were studied. Finally, a
confirmation experiment with the optimal levels of the process parameters was carried out to demonstrate the effectiveness of the
Taguchi method.
