  1. 1. Investigation into Melting Characteristics of Hydrogen-Reduced Iron Ore Pellets

    University essay from KTH/Materialvetenskap

    Author : Hedda Pousette; [2019]
    Keywords : Iron Ore Pellets; Sulphur; Phosphorous; Slag; Hydrogen Gas; Järnmalmspellets; Svavel; Fosfor; Slagg; Vätgas;

    Abstract : What kinetic and thermodynamic characteristics are established in a melt of hydrogen-reduced iron ore pellets? The pellets contain self-fluxing slag components which upon melting form an initial slag. Refining capabilities of this slag, such as dephosphorization power, are investigated in a lab-scale vertical furnace. READ MORE
