Hydrogen‐Based Reduction of Hematitic Iron Ore in a Fluidized Bed Kinetic Reactor at Elevated Pressures

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 ...

Experimental and Computational Investigation of Slag–Refractory Interactions Under Conditions Relevant to Hydrogen Plasma Smelting Reduction

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.

Isothermal Reduction Behavior and Microstructural Evolution of Iron Ore Sinter Under Simulated Radial Blast Furnace Gas Atmospheres With Hydrogen Injection

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.

Forensic Analysis of Fountain Pen Calligraphy–II. Real Evidence Analysis at the Public Prosecutor's Office

X-Ray Spectrometry, EarlyView.
ABSTRACT The present study is a report of the real forensic analysis of characters written by fountain pen(s) on two sheets of paper. One sheet is the calligraphy written by the victim of the Sayama incident. The other is number characters written with a fountain pen found on the lintel of the suspect's house.

Integration of Micro‐CT and XRF Mapping for Multimodal 3D Analysis of Polychrome Wooden Artifacts

X-Ray Spectrometry, EarlyView.
ABSTRACT Over the past 5 years, computer applications have become crucial to archeological research. Since the 1990s, the focus has transitioned from data management tools to the development of virtual models. Recently, digital documentation of cultural heritage has gained considerable focus, with 3D modeling of objects.
