Characteristics. As mill scale is a quite uncommon cargo, knowledge of its qualities is scarce. However, for practical purposes, the cargo can be compared with iron ore fines. It possesses a Transportable Moisture Limit (TML) and is liable to liquefy and/or form a wet base unless appropriate measures are taken.

In large-scale mills the purified and dried oil is transferred to a tank for storage prior to dispatch from the mill. Since the rate of oxidation of the oil increases with the temperature of storage the oil is normally maintained around 50°C, using hot water or low-pressure steam-heating coils, to prevent solidification and fractionation.

Mill scale is a very attractive industrial waste due to its richness in iron (~72 % Fe) [11]. Approximately, 90% of mill scale is directly recycled within steelmaking industry and small amounts are used for ferroalloys, in cement plants and in the petrochemicals industry [12-16]. The author of the paper [17] studied the effect of recycling ...

The colour of primary mill scale is generally bluish black while that of the secondary scale is blue. The secondary scale gives the steel an appearance which is similar to that of a lacquer coating finish and is often mistaken for a blue coloured primer.
