  • Maximizing Iron Unit Yield from Ore to Liquid Steel Part

    Maximizing Iron Unit Yield from Ore to Liquid Steel Part

    Iron units represent the largest operating expense of a direct reduction plant, and metallic iron units represent the largest operating expense of an EAF steelmaking plant. Increasing or decreasing yield by a few percentage points can have a greater impact on total operating cost than a 50 swing in energy cost. Yield is king when evaluating cost at the metallic iron unit stage, as well as at the liquid metal stage.
