Experimental Study on Surface Deterioration of Hot Rolling Mill Rolls under Near Service Conditions

With specially designed hot rolling test equipment,the surface deterioration process of hot rolling mill rolls can be simulated and representative samples were obtained. Thus a series of micro-analyses can be done onto the sample's worn surface, including wear loss, worn surface morphology, wear mode, oxidation and other influences from environment conditions. A leading study has been done with a high chromium cast iron to show the rolling test conditions and the methodologies of follow-up investigations for all the above-mentioned microanalyses. Primary results have shown that high chromium iron roll may undergo complex degrading mechanism, and most of them can be investigated with the help of this research method.
