Abstract

Hot rolling tools composed mainly of Fe, such as plugs for seamless pipe rolling, is generally used with iron oxide scale on the outer surface of the toolThis is to inform you that corresponding author has been identified as per the information available in the Copyright form.. Oxide scale affects the tool life as a protection from seizure to the rolled material and the heat flux caused the tool’s deformation. Therefore, the tool life depends on the remained the oxide scale against wear and peeled off, and the improvement of the wear resistance of the scale is needed.

The wear resistance of the scale varies greatly depending on the tool’s composition, oxygen concentration, water vapor content during heat treatment and heat treatment pattern. In this report, we focused on the most influential chemical composition of the tool. The amount of Cr affected the generation of oxidation, so the effects of Cr concentration and scale composition on the wear resistance were investigated. As the results, the Magnetite composition ratio of the oxide scale depended on the Cr concentration and that was strongly affected the tool life.
