Hydrogen Direct Reduction: History and Pathways for Cost Reduction
cScience, Volume 1, Issue 1, December 2025.ABSTRACT The steel industry, a critical pillar of global economic development, is highly energy‐intensive, accounting for approximately 7%–9% of global energy‐related CO2 emissions. The transition from traditional carbon‐intensive metallurgy to hydrogen‐based metallurgy represents a pivotal pathway for the green and sustainable development of the steel

Positioning Coke Particles in Iron Ore Sintering.
ISIJ International, 1992 Coke is the most widely used solid fuel in iron ore sintering. Generally coke is blended with the other sinter mix components dry before granulation. Several studies in the literature have shown that, in addition to the properties of coke, e.g., size distribution, the delayed introduction of coke into the sinter mix, e.g., added towards the discharge ...

cScience, Volume 1, Issue 1, December 2025.ABSTRACT The steel industry is among one of the largest CO2 emitters in the world. To meet climate targets, replacing fossil‐based carbon with renewable biocarbon in metallurgical processes, particularly in blast furnaces (BFs) and electric arc furnaces (EAFs), has emerged as a viable short‐ to mid‐term solution.

Review on the Phase Equilibria in Iron Ore Sinters
ISIJ International, 2020 Abstract Sintering process is a commonly used pre-treatment process for iron containing burden materials with an aim to produce porous, agglomerated sinter material with suitable properties to be charged into the blast furnace. During the sintering process the material undergoes a series of reactions, during which the conditions vary considerably ...
