Pearlitic Nodular Cast Iron Roll (static/centrifugal)
Ni, Cr and Mo are enhanced the nodular cast iron then the pearlitic spheroidal graphite cast iron roll is produced through the special heat treatment. Pearlitic spheroidal graphite cast iron roll has good strength, high temperature performance and anti-accident/emergency performance as well as the low hardness gradient of working layer.
