Spheroidal pearlite Alloy Roll Spheroidal pearlite Alloy Roll is pearlite in matrix was accounted for more than 80% of the nodular cast iron roll. Nodular cast iron, nickel, chromium and molybdenum alloy element in pearlite ductile iron roll with special heat treatment. Pearlitic nodular cast iron roll has a good strength, high temperature performance and accident resistance, low layer hardness drop.

Pearlitic Alloy Nodular Cast iron roll Alloy elements of NI,Mn,Cr,Mo etc, are added to bainitic nodular cast iron rolls to obtain acicular(bainite-martensite)matrix in its microstructure of these rolls. Its strength and toughnes is higher than Perlitic Nodular Cast Iron Rolls, wearability is also better than latter.
