The formation, composition, and microstructure of mill scale are briefly introduced. The mill scale formed at a relatively higher temperature with a rapid cooling is usually composed of FeO, Fe 3 O 4, and Fe 2 O 3 from inside to outside, forming a trilayer structure. Nowadays it is mainly composed of Fe 3 O 4 obtained by the controlled rolling …

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

Over the decades, with decreasing ore deposit grades, miners have turned to economies of scale and bulk mining to gain an advantage. This has resulted in an inherent dilution of feed to the mill. However, a point is being reached for most ore deposits where the mill feed grades for the selective mining unit (SMU) sizes are too low to be deemed ...

The Root of Mill Scale. Mill scale is also known as iron oxide.It is a hardened surface on hot rolled steel that is formed during the milling process. In his book "Corrosion Prevention by Protective Coatings", Munger explains that the oxide layer coaters typically encounter is formed by the latent heat once the metal has been shaped and is cooling.
Mill scale is the flaky surface that forms on hot-rolled steel. It is a by-product of manufacturing hot-rolled metal plates and sheets, occurring as the surface oxidizes during the heating, conditioning and hot-rolling processes. It usually has a bluish-black appearance and can be flaky or powdery.
