Mineral Phase Ratio of MEBIOS Sinter and its Reducibility under Blast Furnace Condition with High Hydrogen Concentration

For decreasing carbon dioxide emission from iron- and steelmaking industry, hydrogen utilization in the blast furnace has been considered. Iron ore sinter is one of the major iron sources for the blast furnace. It is known that the effects of the hydrogen concentration in the reducing gas on the reducibility and reduction disintegration of the sinter are strong. In this study, the evaluation of the mineral phase of the Mosaic EmBedding Iron Ore Sintering (MEBIOS) sinter and reducibility using a laboratory scale furnace simulated the blast furnace condition with high hydrogen concentration and the experimental blast furnace were carried out.
