Mill scale (often known simply as 'scale') refers to the thin, flaky texture that forms on the outer surface of hot-rolled iron oxides and metals. 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.
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).
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. Mill scale is bluish-black in color. It is usually less than 0.1 mm (0.0039 in) thick, and initially adheres to the steel surface and protects it from atmospheric corrosion provided no break occurs in this coating.
Mill scale is a byproduct of iron and steel industries  and its annual production is estimated about 13.5 million tons . It has specific properties such as high density, magnetic attractions and the ability to bridge with other charged particles/molecules via electrostatic attractions or hydrogen bonding [ 25, 26 ].
2020/5/28Mill scale is a very thin layer of brownish to black material that forms when people pass steel through a hot mill to roll and shape it. Companies producing sheet metal usually utilize milling because it is cost effective, and the mill scale is an unwanted byproduct of the process. There are several

2013/2/19Hey guys (and gals if any should be reading), I was wondering what all of you use to remove your mill scale from hot rolled steel. I've been using flap discs and roloc sanders but i was wondering if anyone else had something they used that works better. I'm tired of
Everyone should know by now that you need to remove mill scale prior to welding.Unfortunately, it is one of those awful tasks that nobody wants to do. Why? Because mill scale is a pain to get off and an even bigger pain to get off without impacting the material
Mill scale is molded on the outer exteriors of billets when they are being manufactured in rolling mills. It is an assortment of iron oxides, regularly, ferric and is dark in color. It is commonly less than 0.1 mm and primarily follows the steel exterior and protects it from

2020/8/3Traditionally, however, this type of mill machine has been used to mine gold, silver and copper. When copper ore is processed, the coarse material that remains after processing is stamp sand. A stamp mill, sometimes called a stamping mill, is constructed with a series of stamps arranged in what is normally a wooden frame.
Mill scale is a flaky surface that forms on hot rolled steel while the metals are being treated in rolling mills. Mill scale consists of iron oxides and is a combination of black and blue in color. Mill scale is initially useful in protecting the meta beneath it from environmental corrosion, however it has unwanted effects after time once the metal is being processed.
Mill scale also can impede penetration into the base material and cause a lack of fusion and weld inclusions. The greater the thickness or severity of the mill scale, the more challenges there are in welding the material. You can avoid or minimize these but the
