  • Kamat: Hydromechanical descaling

    Descaling Steel hydromechanically With KAMAT high-pressure pump systems, slabs and billets in rolling mills can be efficiently descaled hydromechanically. With the annealing of steel, oxygen reacts with iron on the hot metal surface. Iron oxides, so-called scale, arise.

  • Mill scale

    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.
