Mill scale is the blue and black colored coating on the surface of hot rolled steel. Typically, any breaks in the mill scale coating will have areas of accelerated corrosion causing rusted pits in the surface of the steel. We can remove this mill scale and smooth out most pitted steel by abrasive media blasting the surface until it comes off.

Steel Mill Scale Pit Benefits from CustomEngineered Working closely with the steel mills engineers that designed the new scale pit, the Oil Skimmers, Inc. team identified an opportunity to provide a customengineered oil removal solution that was more effective versus
Jun 23, 2014#0183;#32;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. The thickness is about 1mm and bonds to steel surfaces, protecting them against atmospheric
The scale pit is used to remove the larger scale and particulate, as well as to skim the oil from the water and is normally sized for 3045 minutes of retention time. In some mills, this pit also receives wastewater from the hot roll and other miscellaneous processes throughout the mill.
Jan 03, 2010#0183;#32;the first pit is called the scale pit because the water also collects the free scale off the steel. this scale has to be collected and dealt to, usually settling in the pit. the working height of...
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.
