Mill-scale on steel and welding are like water and fire. This is not the best combination. There are two main reasons for this: The higher melting temperature of the mill-scale. The poor heat and current conductivity. In the most common mill-scale, the melting temperature is slightly higher than that of the steel and additional arc energy is ...

Mill scale is iron oxide that forms on a surface during hot rolling of steel. During rolling, the high temperature involved causes oxide to form over the entire surface, which only increases in quantity as the rolling process progresses. The spots are often hard, but at the same time very brittle. The combination of the […]
Mill Scale. Mill scale is molded on the outer exteriors of billets when they are being manufactured in rolling mills. It is an assortment of iron oxides, regularly, ferric and is dark in color. It is commonly less than 0.1 mm and primarily follows the steel …
Mill scale is a severe nuisance in steel processing. Any coating applied on top of the scale goes to waste. This happens because the steel can be laden with moisture when air gets into it. Electrochemically, mill scale is cathodic compared to steel, so any kind of breakage in the scale could lead to accelerated corrosion in the steel at the ...
The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

In part seven of the 8-part South Ridge Line series, Dean Freytag demonstrates how to build a steel mill. He begins by identifying the parts of a steel mill including what goes inside a steel mill. The Lil' Norma Blast Furnace is modeled on the South Ridge Line. The furnace is 165 feet high and modeled to HO scale.
Steel surfaces can sometimes exhibit residual mill scale as a side effect of the production process. Though not harmful in and of itself, the presence of scale is detrimental in conditions where corrosion is likely to occur, and it must be removed before a workpiece can be given a protective coating.
Mill scale is porous and poorly adherent scale of magnetite, it will only give limited short term protection to steel against corrosion. If you are coating any steel surface against corrosion it is necessary to blast clean (with garnet or similar) to a finish of Sa2.5 blast standard before coating. Regards. Vijay.
