Graphitized Or Graphitic Rolls, Reels & Rings

Graphitic Steel Base Roll is similar to normal steel base but these rolls have the structure consists of Carbide in a Pearlitic matrix with free Graphite. Therefore, it is known as Graphitic Rolls. By modification of the alloy 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 Roll due to presence of the graphite improves the fire-crack resistance of the roll material and reduces thrust collar wear and the side wears which occurs during indirect heavy reduction

Product Application

Application of Graphitic Steel Base is very suitable according to Hardness & Chemical Composition range as per below:

Rolling Mills Mill - Type Stands - Position Pass - Condition
Heavy Section, Medium Section, Light Section, Beams, Rail & Bar Mills 2 & 3 Hi or Universal In all stands (Rough, Intermediate & Finish) In case deep groove pass, Hireduction – ratio & Hi - thermal load
Medium & Narrow Strip TMT & Wire load Rod Mills 2 & 3 Hi Only on Roughing Stand
Heavy, Medium & Light Section Mills Can be used for Straightening Rollers (Reels)
