Corrosionpedia - What is a Mill Scale? - Definition …

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 point of breakage. Thus, the scale is considered an advantage for a short time until the coating cracks due to mechanical factors such as the handling of steel as well as other processes such as abrasive blasting, pickling and flame cleaning.

What exactly is Mill Scale and what is done about it

2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.

Surface scale is removed from the heated slab, which then becomes thinner and longer as it is squeezed by horizontal rolls at each mill, usually called roughing stands. Vertical rolls at the edges help control width. The steel next enters the finishing stands for final reduction, travelling at speeds up to 80 kilometres per hour as it crosses the cooling table and is coiled.

Pickling Steel | American Galvanizers Association

Low-temperature mill scale consists of two iron oxide layers and develops when steel is heated in an annealing or finishing procedure at less than 1070F. Cracks in either type of scale allow the pickling acid to penetrate the scale layers and dissolve the inner layer, causing the bulk of the scale to be removed in flakes. After the iron oxides are removed, the steel should be immediately ...
