Mill scale is a thin, flaky layer of iron oxide that forms on the surface of hotrolled steel. It is used as a protective coating during storage and transport to prevent corrosion of the underlying steel. When welding, the mill scale must be removed from the surface of the metal to ensure a strong bond between the two pieces.

Harold (and possibly others) recommended vinegar to remove mill scale from hotrolled steel. I decided to give it a shot. Ordinarily, I would use abrasives or electrolysis, but abrasives don't do well with the magnetite in scale (Mohr hardness +), and electrolysis tends to put magnetite ON things. Yesterday I took four pieces of steel I had ...

The process byproduct of mill scale from the rolling process containing >70% Fe is generally recycled into the sintering plant. Generally, 70 mill scale containing high iron is being recycled through either briquetting or sintering route with out any difficulties. In some cases, deoiling of the material is required.

50 micrometers ( m) or smaller by grinding, using smooth rolls, media mills, autogenous mills, hammer mills, or jet mills. The ground material then is classified by wet screening, dry screening, or air classification. At some plants, after initial crushing and screening, a portion of the sand may be diverted to construction sand use.

Legodi et al. studied the potential of mill scale iron waste to obtain pigments based on iron oxides. They obtained pigments (from mill scale) under < mm, with a high surface area. In the case of corrosion product appearance, mill scale has a poor color, exposed hardness, and it is difficult to use as a pigment.
