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 ...

Mill scale is a flaky surface that can be found on iron oxides and metals that have been hot rolled. Mill scale forms on exterior surfaces of sheets and plates as they are being manufactured through rolling steel billets and hot iron into rolling mills. Mill scale typically consists of iron oxides that are bluish black.

For pellets produced in the bench-scale pellet mill, the procedure was the same but the density was measured for 40 pellets of each run. 2.2.3.2. Heating value. The higher heating value (HHV, MJ/kg) of pellets produced in the bench-scale pellet mill was measured using a bomb calorimeter (6300, Parr Instrument Company, USA).

Remarks: Mill scale is formed during the oxidation of the steel surface during reheating, conditioning, hot rolling, and hot forming operations. This substance is usually removed by process waters used fordescaling, roll and material cooling, and other purposes. It is subsequently recovered by gravity separation techniques.
