iron ore mill scale process

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 contains65–70% iron. JSW Steel Ltd is a 7 Mtpa integrated steel plant and generates 270 t of mill scale per day.

A. Mill scale is the result of anoxidizing layer of steel productsas it is processed in arolling mill. It is collected with coolant and lubricating oils and normally held in a collection tank/pond. During its mixture with the liquids the steel scale will oxidize further until it reverts to iron oxide (Fe2O3).

Nov 29, 2013· Mill scale is an iron oxide waste generated during steelmaking, casting and rolling. Total generation of mill scale at JSWSL is around 150 t/day and contains 60–70%FeO and 30–35%Fe 2 O 3. To recover the iron, the mill scale must be smelted in a blast furnace or other reduction furnace; however, it is usually too fine to use without previous agglomeration such as via pellet or sinter mix.
