statically cast and undergo
a three stage high temperature heat treatment
comprising of annealing, normalizing &
tempering rotation. the rollers are available
in a wide variety of composition & properties
to suit specific application.
The matrix structure is pearlitic or bainitic
depending on the alloy content. changing
the carbide distribution obatined through
control of chemical composition varies the
hardness. finishing rollers for sheet, plate
and strip mills. intermediate and finishing
rollers for small section, bar and wire
rod mills. also used as cold mill rollers
for ferrous and non-ferrous sheets |
