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 ...

Damage Investigation of the Preform Operations for the Production of Rings for Ring Rolling

steel research international, EarlyView.
Void evolution during the preforming operations of two industrial ring rolling process routes is investigated by combining metallographic characterization with a two‐scale finite element simulation approach. The results reveal that, despite differing initial void conditions, the preforming operations can be designed to effectively influence void ...

A Critical Review on Nitrogen Control in the Scrap‐Based Electric Arc Furnace Steelmaking Route to Produce Low‐Nitrogen Steels

steel research international, EarlyView.
In primary electric arc furnace (EAF) steelmaking, carbon boiling removes nitrogen from liquid steel and sustains slag foaming. In 100% scrap‐ or hydrogen direct reduced iron (HDRI)‐based EAF steelmaking, carbon boiling is absent; therefore, carbonaceous material and oxygen injection into the slag is needed to maintain foaming and avoid nitrogen ...

Hybrid Temperature Modeling for the Ruhrstahl–Heraeus Process: Coupling a Data‐Driven Approach With a Physics‐Based Process Model

steel research international, EarlyView.
A hybrid framework combining a mechanistic tanks‐in‐series model, thermodynamic data, and statistical learning methods was developed for continuous temperature prediction during RH vacuum treatment. The framework accounts for temperature changes caused by alloy additions, O2 blowing via top lance, and heat losses to the surroundings. Validation against

Thermo‐Catalytic Routes and the Emerging Potential of Photo‐Enhanced Strategies for Sustainable Aviation Fuel Production

SusMat, EarlyView.
Sustainable aviation fuel (SAF) offers a promising route to reduce aviation‐related carbon emissions and support net‐zero goals. This review summarizes major SAF production approaches, including thermo‐catalytic (TC), photocatalytic (PC), and photoelectrocatalytic (PEC) processes.
