Extraction of Vanadium from CaO–SiO2–MgO–Al2O3 Slags Based on Vaporization of Vanadium Pentoxide

steel research international, EarlyView.
In the present article, fundamental reaction mechanisms for the extraction of vanadium from CaO–SiO2–Al2O3 slags based on vaporization of V2O5 are investigated. Several parameters influencing the vanadium extraction are analyzed. The results make it possible to develop innovative methods for extracting vanadium from slags.

Influence of Carbon Material Properties on Slag‐Foaming Dynamics in Electric Arc Furnaces: A Review

steel research international, EarlyView.
This article examines how the properties of the carbon materials affect the slag foaming, emphasizing the need for strategies to improve the effectiveness of biochar, such as pelletizing or blending with coke. Biocoke appears as promising but underexplored option for enhancing slag foaming.

Effect of SiO2 and Al2O3 on the Thermophysical Properties and the Foaming Index of Electric Arc Furnace Slag from the Production of Construction Steel

steel research international, EarlyView.
. Future steelmaking slags are expected to change due to the implementation of direct reduced iron, affecting slag properties and the associated processes. This study examines how SiO2 and Al2O3 impact the viscosity, density, and surface tension of electric arc furnace slag in construction steel production and analyzes their influence on the foaming ...

Thermodynamic Constraints and Prospects for Intensified Steel Deoxidation

steel research international, EarlyView.
The article provides a short survey of steel deoxidation and considers how to increase its efficacy. Bringing a specially tailored, powdered slag into the reaction site can directly bind the deoxidation product oxides, resulting in lower dissolved oxygen activity, total oxygen content, and cleaner steel.

Power‐to‐X Processes with Synthetic Iron Oxides

steel research international, EarlyView.
Iron oxide redox cycling connects electrolytic hydrogen production and storage, enabling synthesis gas generation for synthetic hydrocarbons. Integrating H2/CO2 cycles offers carbon‐neutral energy storage and industrial applications, especially in commodity chemical industries. An aluminous‐rich binder stabilizes a sample over 20 H2/CO2 cycles, without
