A. Mill scale is oxides of iron and alloying elements present in steel. Obviously, it is a rich source of iron. Most of the steel plants recycle mill scale through sintering or pelletization. However, a value-added utilization of mill scale is in steel making after converting it into briquettes.
Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills. Mill scale is composed of iron oxides mostly ferric and is bluish black in color. It is usually less than 1 mm (0.039 in) thick and initially adheres to the steel
Sieve analysis, chemical composition, and XRD examination of mill scale were carried out. Reducing agents (crushed coke and crushed broken graphite electrode waste) and fluxing materials (CaO, CaF 2, CaSi, Al 2 O 3, and Na 2 CO 3 ) chemical compositions were determined.
