Evolution or revolution to produce steel : direct reduction vs. smelting reduction*
Évolution ou révolution dans les procédés d’élaboration de l’acier ?
Reduction is an important step in steelmaking. Two routes have practically been developed : a smelting reduction route, and a melting route.
This situation can be changing :
– gradually (« evolution »),
– or radically (« revolution »), with the research effort.
The article aims at giving the state of the art, with regard to direct reduction, smelting reduction, and the possibilities of « direct steel ». It concludes that three routes can be envisaged in the future.
