A Review of Mathematical Process Models for the Electric

1 Introduction. The electric arc furnace (EAF) constitutes the main process in scrap‐based steelmaking. [] Invented in 1889 by Paul Hroult, 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 2021, the EAF process supplied 523 918 000 t of steel worldwide, accounting for
