Bharath Roll Industries Pvt. Ltd. Arekere, Bangalore, Karnataka

These rolls are spun cast with highly alloyed shell consisting of Nickel, Molybdenum and Chromium. The Core can be grey iron with flake graphite, iron or spheroidal graphite iron depending on the mill requirement of neck strength.The shell micro structure consists of bainiticmartensitic matrix with carbides and fine graphites. The micro structure offers excellent surface finish to rolled product along with bruise and crack resistance due to presence of graphite which can be altered depending upon the rolling condition.

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. These Rolls are suitable for rolling medium and heavy sections. These rolls are also used for roughing stands of strip mill.
