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. There are two main technologies for direct reduction of iron, Midrex and Energiron (or Hyl) which together are responsible for 80% of the production of direct ...
