Jun 21, 2011· Mill scale or rolling scale, was handled with salt on a hot strip. The practice was abandoned because of the corrosive effects to the equipment as well. Commonly Sulfuric is used for cold metal, and HCL heated to 160* or better is used to treat hot roll. The Trick is HCL must be 'activated' or have Ions available to exchange with the oxides.

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.
