scale drops into a flume and is carried by a stream of water to a scale pit. The volume of water used in this opera tion varies with the stock being rolled, but it will usually fall in the range of 2,000 to 4,000 gpm. Mill scale may contain upward of 70 per cent iron as a mixed oxide and is equivalent to very high grade iron ore.

In steel production, hot milling and casting uses water at rates of between 100m3/h and 10000m3h depending on the scale of the operation. As steel leaves the casting operations, cooling and cutting with water produces mill scale (iron oxides). Mill scale particles range from a few microns up to the size of a fist. They are heavy and abrasive.

Mary McMahon. Mill scale is an unwanted byproduct of passing steel through a hot mill. Mill scale is a very thin layer of brownish to black material that forms when people pass steel through a hot mill to roll and shape it. Companies producing sheet metal usually utilize milling because it is cost effective, and the mill scale is an unwanted ...
