Slag formers are either charged with the scrap or blown into the furnace The Si and Al in the scrap are oxidized first to form SiO 2 and Al 2O 3 fluxing oxides As oxygen is blown into the furnace the principal flux FeO is generated The slag balance now starts to shift and the slag becomes more liquid
