Impact of low Fe iron on green steelmaking
Today's DRI-EAF green-steel making process is heavily dependent upon iron ore with high Fe content. The global availability of such high-grade ore however is limited and trends show declining grade quality with increased usage of a mine. This workpackage therefore explores alternative avenues for the use of iron ore with low Fe content for sustainable steelmaking.
About this project
The project aims to facilitate the usage of ores with low iron content for hydrogen-based steelmaking by developing an understanding of the fundamentals of direct reduction of low-grade iron ore pellets with a combination of reducing gases (CO and H2).
Research Plan
- To understand the fundamentals of BF and DR grade pellet reduction using CO/H2/CO + H2 gas mixtures - Experiments to be done using TGA for single pellet and multiple pellets
- To understand the kinetics of the reaction for better understanding the role of gangue elements
- To generate a numerical model that can replicate the shaft furnace operation for a variety of iron ore pellets and reducing gases ('digital twin')
