Infinite chilled casting iron roll, distinguished from chilled casting iron rolls, graphite is uniformly dispersed throughout the cross section of the roller body.
By higher contain of Mn, Cr, Ni, Mo and other alloying elements, and with the presence of fine graphite. The thermal cracking resistance, and anti-wear properties are significantly improved.
