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.

Roller mill

Each pair of rolls is counter rotating. For improved size reduction one of the rolls rotates faster. This results in a differential in speed between the roll pair. Typical differentials range from 1.2:1 to 2.0:1 (fast to slow). Typical roll speeds would be 1,300 feet per minute (~ 395 m/min) for a 9-inch (~23 cm) roll to 3,140 feet per minute

Automotive Paint Inspection—Paint Meters

Eddy Current Principle for Measuring Paint on Aluminum. Paint thickness over all other metals such as aluminum is measured using an eddy current technique. When the instrument's probe is brought near a metal (conductive) surface, a coil within the probe generates an alternating magnetic field that sets up eddy currents on the metal's surface.
