ROLLER HEARTH KILNS • Tailor-made process requirements • 4-tray, 6-tray width with multiple layer configuration • High O 2 atmosphere > 99 % • Inert gas atmosphere (N 2, Ar, CO 2 and others) < 30 ppm O 2 • Special atmosphere (H 2, CO, CH 4 and others)
In a compact that contains only iron powder particles, the solid state sintering process would generate some shrinkage of the compact as the sintering necks grow. However, a common practice with ferrous PM materials is to make an addition of fine copper powder to create a transient liquid phase during sintering.
Using powder metallurgy is one way to do that. Powder metallurgy involves mixing and sintering iron-based alloy structural components. These components are pressed in a die that determines the basic part shape. Raw Materials Metal powders are used in the
