The Application of Hydrochar Composite Briquettes for Sustainable Slag Foaming in the Electric Arc Furnace Process

steel research international, EarlyView.
Hydrochar‐mill‐scale briquettes with varying C/O molar ratios (0.07–0.90) have been tested at 1650 °C to evaluate their slag foaming performance for electric arc furnace application. All seven briquette recipes developed succeed in promoting slag foaming.

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 ...

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.

Hydrogen Reduction of Synthetic Fe2O3 Pellets: The Role of Calcium Oxide in Porosity Evolution and Reduction Kinetics

steel research international, EarlyView.
At 800 °C, hematite pellets containing 0.9 wt% CaO reduce in hydrogen at rates 1.2–1.4 times those of pure pellets. The inward‐moving reaction front supports a topochemical description, and FeO‐to‐Fe kinetics are consistent with mixed control by interfacial reaction and intrapellet diffusion.

Stresses in Above‐Ground Storage Tanks Subjected to Flood‐Borne Debris Impact

Safety Science and Technology, EarlyView.
This study investigates the stresses induced in above‐ground storage tanks by flood‐borne debris, specifically steel pipes and wood poles. Findings demonstrate that debris impacts across the examined velocity range generate stresses within safe limits, not exceeding the yield stress threshold.
