EFFECT OF MANGANESE, SILICON AND CHROMIUM ADDITOIN ON MICROSTRUCTURE AND WEAR CHARACTERISTICS OF GREY CAST IRON FOR SUGAR INDUSTRIES APPLICATIONS

Abstract
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.
