DRI converts raw iron ore to sponge iron, a porous, permeable, and highly reactive product that requires treatment with EAF before selling to market. One of the well known hard-to-abate sectors, substantial iron and steel industry decarbonization will increase production cost significantly (>120 $/ton) [(ETC, 2018)].
As the iron ore descends through the furnace, the reformed reducing gas reacts with the Fe 2 O 3 in the iron ore and converts it to DRI, leaving H 2 O and CO 2 as off-gas (Kolbeinsen 2010). The top gas from the reduction shaft is recycled and mixed with fresh natural gas and fed to the MIDREX reformer (Parvizi et al. 2018 ).
The iron pellets are produced with cold crushing strength (CCS) of 210+ and porosity of 24+" which helps to maintain grade in DRI fem – 80+ and our product mean particle size (MPS) is ~9.5-10 which assists in reducing oxygen in kiln and maintain consistency in grade. Iron Pellets are used as raw material for sponge iron and blast furnace.
