Ranking of Injection Biochar for Slag Foaming Applications in Steelmaking

open access: yesMetals, 2023
The electric arc furnace (EAF) has the potential to significantly contribute to the decarbonization of the iron and steel industry. However, during EAF steelmaking, carbon still needs to be injected into the molten slag to initiate slag foaming, which is
