Chilled to graphite being smoother, the hardness associated with the definite chilled structure allows deeper grooving. definite chilled rolls are superior in biting performance and have enough strength and resistance against thermal shock occuring at the time of accident in the rolling operation compared to our chilled rolls.

Definite chilled rolls have proved well suited for the finishing stand of rod & section mills, for continuous hot strip mills. these make excellent work rolls for two, three and four mills, turning out of high grade ferrous and non-ferrous sheet and strip or section.

d.p.i.c. rolls are made of a high alloy iron and a soft grey iron or ductile iron core metal. having minimal drop in hardness with a good it is recommended to keep the core as nodular iron (sg iron). better roll cooling is required for these rolls in the mill.these rolls are used in finishing stands of rod mills and for flat rolling. the shell material consisting of predominantly bainitic or martensitic matrix with free carbides with small quantities of tiny flake graphite, have excellent wear resistance coupled with resistance to fire cracking.
