Treatment and characterisation of electric arc furnace
Electric Arc Furnace slag from an integrated steel plant has been characterised for its physico-chemical and mineralogical properties. It is classified as low to medium reactivity slag based on its chemical composition (basicity) and phase assemblage. The melt-quench treatment in a graphite lined furnace failed to yield improved glass content.
