Direct-Reduced Iron - an overview | ScienceDirect Topics

 · The RHF process was originally developed as an alternative to gas-based direct reduction, making DRI from iron ore and coal. The process started from the patent of D. Beggs applied by Midland-Ross Corporation in 1965 [144]. This process was known as Heat Fast [145].SIPS2015 - Direct Reduction of Iron: A Review on .Ironmaking is the major energy consuming and CO2-emmiting step in steel production. Direct reduction processes are an alternative to the traditional blast furnace because of the use of H2 in the reducing gases which generate less CO2.
