Iron & Iron Products #3303025

S.g iron (nodular) or ductile iron rolls are available in a wide range of hardness & composition for a variety of applications. The matrix structure varies from ferro-pearlite, pearlite to bainite and martensite together with different carbide contents and graphite in the form of spheroidsnodules. The rolls are used in roughing, intermediate as well as finishing stands of both heavy & light section mills. Some critical grades are heat treated for higher strength. Chemical composition and structures are chosen to suit specific applications.

We are offering indefinite chilled rolls.These are cast iron based rolls alloyed with nickel, chromium and molybdenum having a matrix of pearlite and carbide with flake graphite.these rolls are used primarily for section rolling. The material has superior thermal properties and imparts better surface finish to the product. These rolls are available in higher hardness ranges where the matrix is bainitic instead of pearlite and are used in finishing stands of rod mill.

D.pi.c. Rolls are made of a high alloy iron shell and soft grey iron or ductile iron core metal.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. These rolls are available in hardness range of 70 to 85 shore c.the core material of these rolls is mostly grey iron but where higher strength is required, the core is made of ductile nodular cast iron.
