Mill scale Wikipedia

May 06, 2009 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.

Revamped water treatment plant saves project investment

Water from the rolling mill is treated first in the scale pit, followed by the decanting process to remove coarse particles that have a size greater to or equal to 200 microns. The density difference between the water and the scale, causes the larger, heavier scale particles to be deposited on the bottom of the pit, and subsequently extracted

Rolling (metalworking) Wikipedia

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
