Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Engineering - Department of Mechanical Design and Production Summary: Mill roller shells are important manufacturing-line elements in the sugar production process. They are carefully designed according to wear resistance is the most important long age. In this investigation, a series of sixty-six cast iron samples with varied contents of chromium, manganese and silicon were prepared. The microstructure and the mechanical properties were studied. Hence, the wear of all the specimens was evaluated using the pin-on-disc test, with a high-speed steel disc. The wear rates were determined at constant normal test load and constant pin velocity. From test results, it was found that the wear rate, for all conditions under investigation, decreases with the increase of manganese and chromium additions at constant silicon additions. The enhancement in the wear resistance of the chromium alloyed samples was attributed to the increase in the chromium carbides volume fraction. From the feasibility study found that there is an estimated annual saving equal to 2,278,848.5 for mill roller shell after development
