First, what is mill scale? Mill scale is the thin layer of iron oxides that form on hot rolled steel. There are three distinct chemical compositions in mill scale, including FeO, Fe3O4, and Fe2O3. Mill scale can vary in thickness from 2 to 100 mils, depending on the quality of the steel and the rolling process. Mill scale is approximately 70% iron.
Mill scale is also used as a de-siliconization agent that is an integral part of the phosphate fertilizer production process. Mill scale can also be used in the manufacture of water-treatment chemicals that are used in agricultural, forestry, fishing, and scientific activities related to research and development.

1. Introduction. MILL SCALE is a mixture of iron oxides [iron (II) oxide FeO (wüstite), iron (III) oxide Fe 2 O 3 (hematite), and iron (II,III) oxide Fe 3 O 4 (magnetite)] that forms on steel during the hot-rolling process. Wüstite in particular is a relatively uncommon phase but may be the dominant constituent of scale at early times before this …

Mill Scale, generated in a rolling steel mill can be a potential material for iron powder production. Mill scale is a combination of different oxides like Hematite (Fe 2 O 3), Magnetite (Fe 3 O 4), and Wustite (FeO) [2], [3].Besides, this multi-oxide mill scale's conversion into single oxide (Fe 2 O 3) is the best-suited route for further reduction into …

Mill scale is less reactive (more "noble") than the steel underneath, and consistent with the behaviour of two dissimilar metals when in contact, the more reactive metal (in this case steel) will oxidise (rust) at the expense of the less reactive metal (mill scale). The mill scale in fact looks like a scale and it can "pop off" the

We now know what the mill scale is and how it is formed, but does it actually do any harm or does it need to be removed? In theory, the mill scale could be a uniform, well adhering layer on the steel and the perfect protective layer. Unfortunately, the opposite is the case. In practice, mill scale has no connection …
A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.
Mill scale is the hardened, oxidized, surface that develops on steel as it is hot processed. It contains iron and oxidized iron but probably poorly defined contaminants like oils and carbonates.
