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 impingement of an intensely hot flame to the surface of structural steel, resulting in the removal of mill scale and the dehydration of any remaining rust, leaving the surface in a condition suitable of wire brushing, followed by the immediate application of paint.
