Why is it considered essential to removed millscale pior to painting?
Mill scale must be removed prior to painting because any breach in the mill scale will cause moisture to get beneath it, causing it to flake off. If there is paint on top of it, and moisture gets below the paint and the scale, both will peel and flake off because the paint is adhering to the mill scale, not the underlying metal surface. Paint should always be applied only over a clean, sound surface.

What is mill scale?
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 or steel mills. Mill scale is composed of iron oxides mostly ferric and is bluish black in color. It is usually less than a millimetre thick and initially adheres to the steel surface and protects it from atmospheric corrosion provided no break occurs in this coating. Because it is electro-chemically cathodic to steel, any break in the mill scale coating will cause accelerated corrosion of steel exposed at the break. Mill scale is thus a boon for a while until its coating breaks due to handling of the steel product or due to any other mechanical cause. It is a nuisance when the steel is to be processed. Any paint applied over it is wasted since it will come off with the scale as moisture laden air get under it. Thus mill scale has to be removed from steel surfaces by flame heating, acid pickling or grit/sand blasting. All tedious operations wasteful of energy. This is why shipbuilders used to leave steel delivered freshly rolled from mills out in the open to allow it to 'weather' till most of the scale fell off due to atmospheric action. Now a days most steels mills can supply their produce with mill scale removed and steel coated with shop primers over which welding can be done safely.
What is the stowage factor of mill scale?

What are the applications of mill scale?
Mill scale by itself is not useful in the steel industry and is often discarded or recycled. Visual artists use it because it produces apparently random patterns.
Is mill scale hazardous?
On the MSDS sheet it is not considered a carcinogen.
Can mill scale be melted can it transformed into any metal?
Yes, mill scale can be melted down and can typically be transformed into metal through a process such as recycling or smelting. Mill scale is mainly composed of iron oxides and can be used as a source of iron in steel production or as a raw material in other metal industries after appropriate processing.
What can Mill Scale be used for outside the Steel Industry?
In the production of cement.
What is the density of mill scale?
The density of mill scale can vary depending on the specific composition and processing method, but it typically ranges from 5,000 to 6,000 kg/m3.
What is the difference between mill scale iron ore fines?
mill scale fines are generated during hot rolling of cast ingot and it can be removed by pickling operation. iron ore fines are naturally available on iron ore and genetared during loading and grinding
