RedIronTM is a direct reduction process using a RHF to convert steelmaking residues in DRI or HBI to be charged in a BF, BOF or EAF for final melting.
A flagship project for this technology is the industrial RHF plant located in the Lucchini steelworks in Piombino, Italy. Developed and built by Paul Wurth, the plant was commissioned in May 2010. The plant is designed to recycle 60 000 tpy of residues and to produce 40 000 tpy of DRI that are briquetted and charged into the BF. The treated materials will be BF and BOF dusts, BF sludge, mill scales and pellet fines.
