Determination of the mechanism and kinetics of melting of carbon-free direct reduced iron (DRI) made using hydrogen reduction to eliminate CO2 from steel production, and its impact on EAF steelmaking process.

The iron and steel industry are the major contributors to global industrial CO2 emissions. Coke making plants and blast furnaces are the largest emitters in this sector. To meet the requirements of CO2 emission mitigation by 2050 to net zero, hydrogen-based ironmaking is an alternative for the fossil fuel ironmaking route. The overall objective of this project is to study the kinetics and mechanism of melting of hydrogen-based DRI using an X-ray fluoroscopy system. Although it is known that melting temperature will be significantly high, melting rate, onset temperature, and its kinetics are unknown. The findings of this project will form a fundamental base for ArcelorMittal Dofasco for potential future design for a fossil-free steelmaking process based on the direct reduction of iron ore with hydrogen.
