Conversion of Mill Scale Waste into Valuable Products via ...

Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic reduction in a ...

What is a Mill Scale? - Definition from Corrosionpedia

2018-6-22  Mill scale is a severe nuisance in steel processing. Any coating applied on top of the scale goes to waste. This happens because the steel can be laden with moisture when air gets into it. Electrochemically, mill scale is cathodic compared to steel, so any kind of breakage in the scale

Analysis of Wear Corrosion on a Mill Scale Filtration System

Mill scale is a thin oxide coating formed outside surface of the steel plates, sheets or profile during hot-rolled production. Mill scale fell off in multi-stage cold rolling process with cooling fluid. Cooling fluid and mill scale need to be separated each other with filtration system. Wetted mill scale makes wear corrosion on the metal bed during filtration process.

The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.
