The bulk chemical compositional analysis of mill scale is normally carried out using X‐ray fluorescence [XRF] spectrometry by the fused bead technique or with the original substance. For the fused bead method, typically, a to 1‐g portion of finely ground and ignited mill scale is mixed
Mill Scale Uses and Applications. A discussion started in 2002 but continuing through 2019. 2002. Q. My company uses iron ore (magnetite) in its process. However, a large amount of mill scale has become available and we are looking at it as a substitute or supplement.
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.
