The mechanism whereby mill scale is formed is generally considered to be of dynamic nature so that alternate formation and reduction of higher oxides of iron are occurred. The final result is a scale composed of layers rich in oxygen at the scale surface and rich in iron at the metal surface [9] .

Mill scale - Wikipedia
Mill scale becomes a nuisance when the steel is to be processed. Any paint applied over it is wasted, since it will come off with the scale as moisture-laden air gets under it. Thus mill scale can be removed from steel surfaces by flame cleaning, pickling, or abrasive blasting, which are all tedious operations that consume energy.

MIG Welding Over Mill Scale
Mill scale is made up of iron oxides and oxides are not desirable in a weld puddle. During welding, mill scale hinders the flow of the liquid weld puddle. In welding processes where there is flux, ( like stick welding and flux core processes) the flux really helps the fluidity of the puddle and also scavenges the oxides into the slag. ...

Mill scale - Wikipedia
Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.
