The melting time of scrap is a factor that affects the Electrical Energy (EE) consumption of the Electric Arc Furnace (EAF) process. The EE consumption itself stands for most of the total energy consumption during the process. Three distinct representations of scrap, based partly on the apparent density and shape of scrap, were created to …

Introduction and motivation for scrap-based aluminum alloys. About 100 Mt (million metric tons) of aluminum are currently produced per year, ∼35% of which comes from scrap while ∼ 40% has already been scrapped in the manufacturing chain [1], [2]. Aluminum is a material with two facets when it comes to sustainability [3], [4].

1 Introduction. The electric arc furnace (EAF) constitutes the main process in scrap-based steelmaking. [] Invented in 1889 by Paul Héroult, it was initially used mostly for production of special steels, but established itself as one of the main steelmaking processes in the later part of the 20th century. [] In 2018, the EAF process supplied 523 918 000 t of steel …
