Pearlitic Nodular Cast Iron Roll
Pearlitic nodular cast iron roll has a high content of Ni and Mo alloys and the pearlite, basanite and martensite matrixes with excellent performance. It has good strength, high-temperature performance and anti accident performance with small hardness drop on the work layer. The nodular cast iron roll usually is used in large blanking machines, section steel tandem rolling, bar and wire rough rolling, intermediate rolling mill. TINVO is a professional manufacturer for a pearlitic iron roll with advanced technology and best prices, the standard of ISO, GB, ASTM, DIN, JIS is guaranteed.
For pearlite nodular cast iron, pearlite content in the matrix structure accounted is more than 80% of ductile iron (nodular iron). The ductile iron conforms to Chinese national standards QT600-2, QT700-2 and QT800-2 belong to pearlite nodular cast iron. This type of ductile iron is usually obtained by normalizing treatment, or it can be obtained by adding alloying elements and cooperating with technological measures. The nodular cast iron roll is mainly used to manufacture parts that require high strength, with certain fatigue strength and wear resistance
