Efficient and effective descaling in the Steel industry

Within the hot rolling mill, descaling equipment is placed before the mill or after the mill stand and it takes the low pressure water from the plant water supply, creates high pressure water, which is sprayed onto the surface of the hot steel to remove the scale. The steel needs to be scale-free before entering the mill stand to ensure that it

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.
