ABSTRACT Hematite pellet is required to be indurated at very high temperature to achieve its good strength as there is no exothermic heat of oxidation unlike magnetite. As mill scale contains mainly FeO and Fe3O4, any minor amount of its addition in pellet can provide in situ heat and enhance diffusion bonding and sintering. In this study, the mill scale …

Mill scale is iron oxide that forms on a surface during hot rolling of steel. During rolling, the high temperature involved causes oxide to form over the entire surface, which only increases in quantity as the rolling process progresses. The spots are often hard, but at the same time very brittle. The combination of the high temperature and the ...

The particle size of the mill scale is a variable depending on the degree of oxidation from 0.5 mm to 10 mm. It was under the average of D 90 = 0.9 mm and D 50 = 0.5 mm with Span of PSD:(D 90-D 10) /D 50 = 1.4 which shows that the size distribution is fairly uniform. As it illustrated in the Fig. 2 of the granulometric analysis of the mill scale and …
