Influence of Input-scrap Quality on the Environmental Impact of Secondary Steel Production
In electric arc furnaces (EAF), different grades of steel scrap are combined to produce the targeted carbon steel quality. The goal of this study is to assess the influence of scrap quality on the recycling process and on the final product by investigating the effect of the scrap mix composition and other inputs, for example preheating energy, on the electricity demand of the melting process.
This project was part of the doctoral thesis of Melanie Haupt
