Indefinite Chill Alloy Cast Iron

These are cast iron based rolls alloyed with Nickel, Chromium and Molybdenum having a matrix of pearlite and carbide with flake graphite. The material has very good thermal properties coupled with property of imparting good surface finish to the product. These rolls are also available in higher hardness range where the matrix is Bainitic instead of Pearlitic.

Application : These Rolls are suitable for rolling medium and heavy sections. These rolls are also used for roughing.

Double Poured Indefinite Chill

D.P.I.C. Rolls are made of high alloy shell and soft grey iron core metal. These rolls are used in finishing stands of rod mills and for flat rolling. The shell material consisting of mainly bainitic matrix with free carbides with small quantities of tiny flake graphite, having 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 grey cast iron.
