Iron Mill scale is a sort of iron oxide that forms on the surface of hot-rolled steel during the rolling process.
Iron Oxide Mill Scale
Iron Oxide mill scale, commonly known as scale, is the granular surface that develops on hot rolled steel.
The elements FeO (iron (II) oxide), Fe2O3 (iron(III) oxide), and Fe3O4 (iron (II,III) oxide) can be found in its composition.
Steel sheets, plates, and profiles will all have mill scaling on them at some point.
It happens in rolling mills when hot steel billets or iron are rolled back and forth.
When steel is heated, conditioned, and rolled, it will come into contact with oxygen, which will cause the surface of the steel to oxidize, leaving behind this flaky residue... iron mill scale.
Iron Oxide Mill Scale Features
On rolled steel, iron Oxide mill scale is typically present and frequently mistaken for a blue primer.
A smooth, bluish-gray surface is produced by the combination of a very high surface temperature and high rolling pressures.
| Title | Description |
| Appearance | Smooth, Bluish-Gray Surface |
| Nature | Solid and Powdery |
| Purity | 69, 63, 62 |
| Size | Dust Size in Microns up to Typically 6 MM |
Mill scale is visually discernible as a black metal powder made composed of tiny chips and particles.
It is solid and powdery in nature.
Mill scale has a specific gravity between 5.7 and 6.2.
The melting and boiling points of mill scale are respectively 1370 and 2760 degrees Celsius.
It has a stable state and is soluble in the majority of strong acids but insoluble in water and alkalis.
It is typically categorized as non-hazardous trash.
Buy Iron Oxide Mill Scale
When buying iron Oxide mill scale, it is important to consider a number of aspects that have an impact on both the quality of your production and the end result.
Iron mill scale can have a variety of purities depending on the amount of iron it contains, such as 69, 63, 62, and others.
Check the quality and amount of iron that was used in the molten iron mill scale shell, and measure the amount of interfering elements that were present in the oxide shell.
Additionally, the size of the iron mill is crucial for the many purposes you must attend to.
The size of the mill scale typically ranges from dust size in microns up to typically 6 mm.
Iron Oxide Mill Scale Price + Buy And Sell
The price of iron Oxide mill scale is influenced by a number of factors.
The country's supply and demand for the product truly determine its price.
Another element that has an impact is the quality of the iron used in the iron mill.
The other factor that affects the pricing is the size of the iron mill scale.
Mentioning the additional element, which is the various chemicals used in the iron mill.
C, Si, Ca, Na, Al, Mn, and other metal oxides may be present in mill scale.
The cost of an iron mill scale per ton ranges from 70 to 90 dollars.
