The rolls are composed by an outer layermade of high-carbon and alloy high speed-steel and an inner core layer madeof spheroidal graphite cast iron.The rollsare manufactured with the horizontal centrifugal casting technology which grantsan homogeneous and fine microstructure。
The external layer is characterized by thepresence of MC-type primary carbides withhigh hardness and tempered martensile matrix with high temperature resistance.

Main features:
>high and uniform hardness;
>high resistance to wear abrasion;
>high resistance to adhesivenessby surface oxide layer;
>high resistance to heat cracksand thermal stress;
>fine and uniform structure overthe external layer.

>An increase in roll lifetime compared with standard cast iron rolls (3-5 times bigger)thanks to longer groove life time(2-3 times)and reduced redressing thickness (-10 to -50%).
>Reduction of heat cracks and mechanical impact cracks compared with tungsten carbide rings.
> lncreased rolling campaign time.
Better surface finishing.
