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.

Pelletizing - Wikipedia

Pelletizing of animal feeds can result in pellets from 1.2 mm (0.047 in) (shrimp feeds), through to 3–4 mm (0.12–0.16 in) (poultry feeds) up to 8–10 mm (0.31–0.39 in) (stock feeds). The pelletizing of stock feed is done with the pellet mill machinery, which is done in a feed mill.. Preparation of raw ingredients. Feed ingredients are normally first hammered to reduce the particle size ...

Mill scale is considered as a valuable secondary raw material in iron and steel production due to its high iron content and low impurities, where its quantity is increasing rapidly with the current demand of increasing world steel production. The pelletization of this secondary raw material is a

WHAT IS MILL SCALE? - Dulux Protective Coatings

Mill scale is often present on raw steel and is frequently mistaken for a blue-coloured primer. Mill scale is a type of iron oxide that is formed on the surface of the steel during the hot-rolling process. The very high surface temperature combined with high roller pressures result in a smooth, bluish grey surface. ...

Generation Transport and Uses of Mill Scale – IspatGuru

Generation Transport and Uses of Mill Scale. Mill scale is the flaky surface of hot worked steel and is formed by the oxidation of the steel surface during reheating, conditioning, hot rolling, and hot forming operations. It is one of the wastes generated in steel plants and represents around 2 % of the produced steel.

Characterization and Reduction Behavior of Mill Scale

This paper presents an initial part of a project devoted to the recycling of mill scale in the form of self-reducing briquettes. First chemical and morphological characteristics of mill scale were investigated and next its gaseous reduction behavior was studied by thermogravimetry. The chemical characterization showed that wustite is the major constituent of this waste matter, with small ...
