Graphitic Steel Rolls is similar to normal steel base but these rolls have the structure consists of Carbide in Pearlitic matrix with free Graphite. Therefore, it is known as Graphitic Rolls. By modification of the alloys content and suitable heat treatment a controlled amount of fine graphite particles dispersed throughout the structure of the rolls are produced. These Rolls are greater than any other steel base Rolls due to presence of the graphite improves the fire-crack resistance of the roll material and reduce thrust collar wear and the side wears which occurs during indirect heavy reduction ratio as well as better strength to thermal-crack along with no drop of hardness.
