Cold DRI (CDRI) Most MIDREX®Plants built to-date produce CDRI. After reduction, the DRI is cooled in the lower part of the MIDREX® Shaft Furnace to about 50° C. This material is typically used in a nearby EAF and must be kept dry to prevent reoxidation and loss of metalization. CDRI is ideal for continuous charging to the EAF.
