New Technologies for Maximizing Operational Flexibility of MIDREX~R DRI Plants: Adjusting Product Carbon in MIDREX~R DRI Products

摘要

Worldwide, there are approximately 70 MIDREX~R Plants producing Direct Reduced Iron (DRI) products such cold direct reduced iron (CDRI), hot direct reduced iron (HDRI) and hot briquetted iron (HBI), or a combination of these forms of DRI (figure 1). Over nearly five decades the MIDREX~R Process has been in use, product carbon levels have varied based on location and use, and in 2015 MIDREX Plants produced MIDREX~R DRI Products with carbon levels of approximately 0.5% to 3%.Indeed, the MIDREX~R Process has the flexibility to produce DRI with controllable and varying amounts of carbon as desired by the plant operator.
