Description:

Pearlitic nodular cast iron rolls are obtained by adding alloy elements of Ni, Cr, Mo into the nodular cast iron and following special heat treatment, so pearlitic nodular cast iron rolls have high strength, good thermal properties and resistance to emergencies as well as small hardness decrease of working layer.
