Energy Efficiency and Iron and Steel Production – IspatGuru

09/09/2014  The energy intensity of this route ranges from 9.1 to 12.5 GJ per ton of crude steel where the input is only the steel scrap. Another way to produce crude steel is by directly reducing iron ore to produce direct reduced iron (DRI). The average energy intensity is typically between 28.3 and 30.9 GJ per ton of crude steel.
