A process for recovering iron/steel from scrap mill scales and fines is disclosed.
A process in accordance with embodiments of the present invention comprises mixing mill scales and fines with coke or other carbon containing fines and sealing the mixture in a container.
de-oiling of mill scale by
extracting oil from the mill scale using a solvent.
heating the mill scale to approximately 800 °C, the oil hydrocarbons are volatilised and clean mill scale is yielded; the volatilised hydrocarbons can be combusted.
Oil enters the sinter feed mainly by addition of mill scale.
Techniques to minimise oil input via dusts and mill scale include the following
The invention relates to a method for processing a heap of debris, mill scale or similar material, particularly wastes containing aluminum such as cuttings, which is/are fouled by oil and accumulates during industrial processes.
The invention relates to a device and method for utilizing waste products, which contain hydrocarbons and iron oxide, particularly mill scale sludges and coal fines in an iron and steel works.
The steel goes through chemical clean which removes all rust, oil and mill scale from the surface before the processing When the cleaning solution has been rinsed off, the coating process ...

(2)() This listing includes ash, residue, slag, dross, skimming, scaling, dust, sludge and cake, unless a material is expressly listed elsewhere.
This leads to the formation of oxides (scaling) which may contain small quantities of pollutants (hydrocarbons, grease, fluorides) from lubrication of frames or steel.
