Effect of Intrinsic Carbon in Hot Briquetted Iron on Melting and Refining Efficiency under Electric Arc Furnace Conditions for Sustainable Steelmaking with Active Use of H2‐Reduced Iron

steel research international, EarlyView.
The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...

Investigating the Iron‐Steam Process for Coupling With SOEC and SOFC: A Step Toward Integrated Hydrogen and Electricity Storage

steel research international, EarlyView.
Fixed‐bed reactor experiments (10 L) validate the iron–steam redox process, bridging material‐scale research and industrial power‐to‐power applications. Coupled with SOEC/SOFC systems, this framework defines critical interfaces for heat and gas management. Results confirm reproducible hydrogen storage and release, demonstrating technical feasibility at

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction

steel research international, EarlyView.
Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in

Agglomeration Behavior of Nonmetallic Particles on the Surface of Si‐Killed Liquid Steel Using HT‐CSLM: An In Situ Investigation

steel research international, EarlyView.
The in situ agglomeration behavior of semisolid Al–silicate inclusions in Si‐killed steel is studied using high‐temperature confocal scanning laser microscopy. Particle motion and interparticle forces at the steel/argon interface are quantified and compared with a modified capillary interaction model.

Analyses of the Deformability and Chemistry of Non‐Metallic Inclusions in QT Steels With Increased Recycling‐Induced Tramp Element Content

steel research international, EarlyView.
This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.

Acute Inhalation Exposure to Ultrafine Carbon Black Alters Mitochondrial Substrate Utilization in the Heart

Environmental Toxicology, EarlyView.
ABSTRACT A majority of deaths associated with air pollution are attributed to cardiovascular and heart diseases. Carbon black that represents the carbon core of particulate matter, a major component of air pollution, has been shown to result in cardiac mitochondrial dysfunction.
