These Rolls are special hyper eutectoid steels alloyed with Nickel, Chromium & Molybdenum. These Rolls are used in breakdown, roughing & intermediate mills for bloom, billet & sections and also for finishing of heavy sections.
These rolls are statically cast and undergo a three stage high temperature heat treatment comprising of annealing, normalizing & tempering cycles. The rolls are available in a wide variety of composition & properties to suit specific application. These rolls normally do not have any drop in hardness along section.
