  • 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.

  • What exactly is Mill Scale and what is done about it

    In a rolling mill where the steel will be stretched and squished the mill scale will first be removed mostly by water jets, or by sand blasting in some shops or by vibrating rolls in others and the mill scale will fall into a pit below the equipment where it will also be joined by rolling mill lubricants and bearing oils and water. From there

  • Rolling (metalworking) Wikipedia

    Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock), bar stock, and rails. Most steel mills have rolling mill divisions that convert the semi-finished casting products into finished products.

    Scale is produced when the hot surface is oxidized by air. This mill scale can reduce corrosion if steel is exposed to air over short periods, however, the corrosion increases if exposed for long periods. Large amounts of mill scale also cause severe pitting corrosion if the surface is in contact with water.
