Perlitic Sphero Rolls

PEARLITIC SPHERO ROLLS 
Sfero Rolling mills have high thermal conductivity and tensile strength due to all the nodular graphite it has. 
Pearlitic Sfero rolling mills provide an excellent hardness profile, which is formed from the body surface to the center these rollers can be used successfully in preparation and mid-benches of rolling mills. When needed, after the foundry in order to eliminate internal stresses during hardening and to transform probable non-transformed austenite phase we use stress relieving treatment and temper heat treatment.
