Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

steel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

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.

Barriers to Steel Decarbonization

steel research international, EarlyView.
Main identified barriers to steel decarbonization Carbon dioxide (CO2) emissions are a leading contributor to global climate change, necessitating urgent mitigation strategies. While various metrics—such as total national emissions, per‐capita output, and historical contributions—define responsibility, determining accountability remains complex ...

Monitoring of historical structural materials with computed tomography

Structural Concrete, EarlyView.
Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

Nature‐Positive Materials Engineering: Carbon Electrodes from Satoyama Biomass

The Chemical Record, EarlyView.
Nature‐positive materials engineering can link satoyama forest stewardship with the design of carbon electrodes for batteries, supercapacitors, and electrocatalysis. By turning underused firewood and charcoal resources into functional carbons, this approach reduces mining footprints while supporting biodiversity, landscape resilience, and regional ...
