Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic reduction in a ...

Abstract During the processing of steel in steel mills, iron oxides will form on the surface of the metal. These oxides, known as mill scale, occur during continuous casting, reheating and hot rolling operations. Mill scale is a valuable metallurgical raw material since it contains 65–70% iron. JSW Steel Ltd is a 7 Mtpa integrated steel plant and generates 270 t of mill scale per day.

Mill Scale DeOiling. Mill Scale is produced in Hot Rolling operations in the iron and steel industry, in which scale is removed from the surface of hot steel through spray water and contact with the rolls that effect size reduction. The scale thus removed typically discharges with the water used for contact cooling to a scale pit, where the ...

2021-5-31 Mill scale consists of oxides of iron, above all, but also the metal alloys that are included in the steel of which the mill scale is formed. Chemically, the mill scale can be compared with iron ore and can frequently be used in similar applications, e.g. as a raw material on production of pig iron, ferrous alloys and cement.

2017-5-23 Mill scale is a rust coating that forms on the surface of newly cast or poured steel. In some cases the steel mill will encourage it to form a protective coating on the casting. The mill scale then is taken off during or before sent to the rolling mill, normally collected with roll coolants and greases.
