Effect of Pre-Reduced Structures on Deformation and Shrinkage Behavior of Iron Ore Pellets under CO and H<sub>2</sub> Reduction

In hydrogen-enriched blast furnace operations, the cohesive zone's coke slits are expected to thin, requiring precise control. The softening behavior of lump ore, iron ore sinter, and pellets is influenced by factors such as reduction degree, gangue composition, and slag viscosity. This study investigates the softening and shrinkage mechanisms of hydrogen-reduced pellets, offering insights into cohesive zone behavior in hydrogen-enriched conditions.
