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.

Choosing the Right Blast Media for Abrasive Blasting

The shape of the article effects how deeply it cuts into the coating and underlying substrate. Shapes are classified according to angularity. Angular particles cut through soft coatings and rust, cleaning faster, and producing sharper anchor patterns. Rounded particles produce a more even, peened surface, good for breaking away hard brittle coatings and mill scale.

RESEARCH ARTICLE Indian Journal of Engineering

It is seen that the specific gravity of mill scale is 4.96, which is nearly two times that of sand (typical values being ≈ 2.65). This means that if mill scale is used as partial replacement of fine aggregates in concrete it would result in denser concrete and hence can be used in high density concreting.

The scale uses a container that allows a volume of exactly 1000 ml. After collecting the sample, the container is hung on a weight scale which measures in grams. The printed scale reads the pulp density directly in grams/ 1ml. Since water density is 1.0 gm/ml, the …

DENSITY UNIT CONVERSION CALCULATOR

Density, Specific Gravity Definition: Density and specific gravity have very similar, but not quite identical definitions. Density is the mass of material per unit volume. Specific gravity is a ratio of the mass of a material to the mass of an equal volume of water at 4 o C. Because specific gravity is a ratio, it is a unitless quantity.

Under visual inspection, mill scale appears as a black metal powder made up of small particles, flake, and chips. Its physical state is solid and powdered. The bulk density of mill scale is in the range of 5.7 tons/cum while the specific gravity is 6.2. The melting point of mill scale is around 1370 deg C and the boiling point is around 2760 deg C.

Solids and Metals - Specific Gravities

The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below:
