Optimizing DRI/HBI for EAF Efficiency by adrianregister is a document available to read on EtoBox.
Educated use of direct reduced iron (DRI) and hot briquetted iron (HBI) in electric arc furnaces (EAFs) can improve energy efficiency, yield, and downstream operating results compared to 100% scrap melting. Optimizing practices such as charge mix, hot charging, and chemical energy use can allow 50% DRI charging to increase productivity over 100% scrap by 34% and reduce costs by $9.72 per ton of liquid steel. Higher carbon and hot DRI can further boost productivity while lowering costs. Downstream benefits l
