Direct Reduced Iron: Description | Oxygen | Cargo

DIRECT REDUCED IRON. DESCRIPTION Direct Reduced Iron (DRI) (B) is a metallic material of a manufacturing process formed by the reduction (removal of oxygen) of iron oxide at temperatures below the fusion point of iron. Cold-moulded briquettes should be defined as those which have been moulded at a temperature of under 650oC or which have a density of less than 5.0 g/cm3.
