    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.
