  • Removing mill scale - Miller Welding Discussion .

    Removing mill scale 05-20-2008, 10:05 AM. Hi guys, Maybe you have a slick way of removing mill scale from hot rolled shapes, typically bar stock. I have tried wire wheels, 36 grit flap wheels on 4-1/2" angle grinder and 36 grit Roloc discs on a 2" air angle grinder. Wire wheel isn't aggressive enough. Sandpaper cuts thru the scale great for a short period then gets dull and just starts ...

  • Pickling and Passivating Stainless Steel

    Stainless steel surfaces form a grey/black scale during hot rolling or forming. This tenacious oxide scale is removed in the steelmill by descaling. A matt grey is left on annealed mill products following descaling and pickling. Mechanical scale loosening roughens the surface. The terms'descaling', 'pic kling' and 'passivation' are often confused, but are distinct processes. It is important to ...

  • 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

    Mill scale can be used in other iron ore preparation for steel making but it may require crushing and grinding it to very specific sizes and too expensive or it can be briquetted and used directly. If it is used directly the further preparation and processes to use it would have to be scrutinized to ensure that it would be efficient and economic to do so. It would be beneficial to use it as it ...
