Descaler Pump Energy Savings | TMEIC
The high pressure water jets are used to remove scale from the steel bars before they enter the rolling mill. Normally high pressure water is bypassed to the water pit when no bar is present, wasting energy. If the roughing mill is reversing, there are descale nozzles on either side, using even more energy.

Rolling Process an overview | ScienceDirect Topics
In steel hot rolling process, humidity can have a significant effect on the growth of oxide scales. Wei et al. [15] reported, for AISI 304 and 304 L stainless steels, that the oxide scales grow differentially the surface. The coating of oxide scales is or nonuniform depending on the grade of steel and the water .

What is a Mill Scale? Definition from Corrosionpedia
Mill scale is a flaky surface that can be found on iron oxides and metals that have been hot rolled. Mill scale forms on exterior surfaces of sheets and plates as they are being manufactured through rolling steel billets and hot iron into rolling mills. Mill scale typically consists of iron oxides that are bluish black.
