After almost half a century of experience in using DRI/HBI in electric arc furnaces (EAFs), and taking into account the decrease of natural gas cost in the USA, it is interesting to revisit some trends and controversial issues around this alternative iron source. This paper reviews aspects like the evolution of iron ore quality and its influence on EAF operation; DRI stockpiling and transport, regarding the risk for self-combustion; optimum charge design; cold DRI/HBI charging (fifth hole, bucket, transporter); hot charging (ways and results); carbon content, metallization and silica in DRI/HBI, and its influence on EAF operation and performance; oxygen / carbon balance; chemical energy and DRI/HBI charge.

There is an important variation in scrap quality and alternative iron sources depending on country and region. esides, a variety of furnace designs are available. This paper looks at the innuence of metallics type and AA design on specific consumption of energy, ooygen and other inputs, as well as on some productivity indicators, based on a survey of published figures of AAs around the world. The results obtained are analysed in detail.
