Foaming of Slag in Electric Arc Furnace – IspatGuru

Slag foaming has become an important and critical practice for the modern electric arc furnace (EAF) since a good foaming slag contributes considerable efficiency and other benefits to the process. The quality of the slag foaming is an important factor in the EAF steelmaking process since it ensures that the heat from the liquid bath is not lost through the EAF walls.
