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. |
