Characteristics of mill scale. Mill scale is normally present on rolled steel and is frequently mistaken for a blue coloured primer. The very high surface temperature combined with high rolling pressures result in a smooth, bluish grey surface. Under visual inspection, mill scale appears as a black metal powder made up of small particles and …

rolling mill which we used for single-layer strip has a two-wide configura tion for powder rolling (Figure la). Tooling has been added to guide powders into the roll compaction zone, and control blades have been de signed and added to regulate the rate of flow of the powder into the mill when necessary.
The powder rolling process has been analysed using the mechanics of powder compaction with a view to the prediction of the thickness and density of the strip. Factors such as roll speed, initial roll gap, feed rate or flowrate of the powder, and friction condition are discussed and a method of analysis taking account of these variables is described. …
