Effect of Coordination Structure of Iron Ions on Iron Oxide Activity Coefficients in the CaO‐SiO2‐FeO‐Fe2O3 Slags at 1573 K Under Oxygen Partial Pressures Between 10−9 and 10−4 atm

steel research international, EarlyView.
Activity coefficients of FeO and FeO1.5 in CaO‐SiO2‐FeO‐Fe2O3 melts have been investigated from the perspective of the coordination structures of iron ions. γFeO are higher than γFeO1.5$$ \gamma_{\text{FeO}_{1.5}} $$. In addition, γFeO1.5$$ \gamma_{\text{FeO}_{1.5}} $$ increases with increasing the ratio of Fe3+(oct) pct./Fe3+(tetr) pct., which ...

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.

Reduction of Basic Iron Ore Sinter under Blast Furnace Wall and Center‐Simulated Conditions in CO–CO2–H2–H2O–N2 Gas

steel research international, EarlyView.
This study investigates the reduction of iron ore sinter in hydrogen and water vapor‐containing gas. It reveals differences in reduction behavior between blast furnace center and wall regions. Results highlight the role of temperature, gas composition, and microstructure in reduction efficiency.
