Bharat Roll Industry Private Limited

Park Street, Kolkata, West Bengal

These Rolls are special hyper-eutectoid steel rolls alloyed with Nickel, Chromium & Molybdenum. The extra Carbon and special alloys give extra wear resistance and strength. These rolls are statically cast and undergo a special high temperature heat treatment process of double annealing followed by tempering cycles to give a micro structure consisting of fine pearlitic matrix with spherodised broken carbide.

Ductile Iron Rolls are available in a wide range of hardness & composition for a variety of application. The matrix structure varies from Ferrito-Pearlitic, Pearlitic to Bainitic & Martensitic together with different carbide contents and graphite in the form of spheroidsnodules. Some critical grades are heat treated for higher strength. Chemical composition and structure are chosen to suit specific application.
