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 Get price
