Experimental and Numerical Investigation of Particle Degradation to Promote Safer Handling of Direct Reduced Iron
Hoisting and Conveying Equipment and TechnologiesThe accelerating transition to low-carbon steelmaking is leading to a rapid increase in the use of hydrogen-based direct reduced iron (DRI) [1–3], making its safe handling and transport increasingly important. DRI is highly porous and reactive, and it is susceptible to particle breakage during conveying and handling processes. The fines resulting from particle breakage not only reduce process utility in electric arc furnaces (EAF) [4], but also increase safety risks, including self-heating and hydrogen formation in contact with air or water, which has led to strict guidelines and restrictions in handling [5, 6]. Minimising breakage and fines generation along logistic chains is therefore essential. Studies focusing on quality related metrics, such as cold compressive strength or abrasion index can be found in literature, e.g., [7–10].
