Direct Reduction Process - an overview ScienceDirect Topics

DRI and HBI are predominantly processed in the EAF, and predominantly for the production of steel grades of long products. Compared to scrap, the advantage of DRI/HBI is low content of trace elements; however, the disadvantage is higher cost (Steel Institute VDEh, 2008). Furthermore, DRI/LRI can also be applied as pre-reduced material for the BF.
