steel research international, EarlyView.This study investigates the reduction behavior of two international iron ores, including a synthetic hematite produced by oxidation of magnetite, in a novel fluidized‐bed kinetic reactor at elevated pressures. The reduction takes place at various temperatures (650°C, 700°C, and 750°C), and various hydrogen partial pressures (30, 55, and 80 vol% H2 ...

steel research international, EarlyView.This study investigates how slag interacts with magnesia–carbon (MgO–C) refractories under conditions relevant to hydrogen plasma smelting reduction. High‐temperature refractory wear tests are combined with thermodynamic modeling to examine refractory dissolution into slag and slag infiltration into the refractory.

steel research international, EarlyView.Commercial iron ore sinter is reduced isothermally under operation‐derived radial blast furnace gas atmospheres with and without 20 kg H2/tHM injection. Hydrogen improves reduction at 900–1100 °C, whereas at 700 °C the high H2O content limits the wüstite‐to‐iron driving force.

Thermodynamics and Kinetics of Ammonia‐Based Reduction of Natural Hematite
steel research international, EarlyView.Ammonia is investigated as a carbon‐free hydrogen carrier for reducing natural hematite into metallic iron. Higher temperature and smaller particle size promote faster reduction, while ammonia dissociation generates hydrogen that indirectly drives the reduction reaction. At 850 °C, high reduction degrees and porous metallic iron structures are achieved,

Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete
Structural Concrete, EarlyView.Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...
