Heavy Duty Submersible Pumps: Forge Solution to Scale Buildup at Steel Mini-mill. Mini-mills were a proven alternative to less profitable integrated steel mills by the time Rodney Agner started his first job as a newly minted electrical engineer in June 1989.
In a rolling mill where the steel will be stretched and squished the mill scale will first be removed mostly by water jets, or by sand blasting in some shops or by vibrating rolls in others and the mill scale will fall into a pit below the equipment where it will also be joined by rolling mill lubricants and bearing oils and water. From there it will be pumped to a holding pond, where
Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.

Scale pit Oil Wash water Static mixer Clean cooling water Thickener Polymer MILL SCALE SEPARATION FEWER FILTERS AND LOWER COSTS Mill scale forms during steel production. It is a thin oxide coating that is created when steel is hot-rolled. When the steel is cooled down with water during the rolling process, the mill scale breaks off. The cooling water is re-used over and over
Direct Cooling Water Circuits In the hot strip mill, high pressure water is sprayed on the hot rolled plates/coils as they move on the turnout table for de-scaling. Water is also sprayed to cool the rollers and bearings .The hot return water, laden with mill scale and lubricating oil, is drained into scale pits.Large and medium sized mill scales
What is Mill Scale? We are sometimes asked to explain the materials we sell, I reference TV programs that show steel manufacturing. When the TV program shows a red hot slab or plate of steel coming out of the steel mill’s furnace: Mill scale is basically the rust coating which forms on the poured steel or newly cast surface.
