Nodular cast iron rolls can be divided into two kinds by their matrix: noe is pearlitic nodular cast iron rolls, the other is acicular iron rolls.
The shell material of pearlitic nodular cast iron rolls consists of spherical graphite and carbides in a pearlitic matrix. We can obtain Cr alloy pearlitic nodular iron rolls if we control suitable Cr content. Rolls of this type which are alloy Cr to achieve a deeper penetration of carbids is belong to pearlitic nodular iron rolls. This kind of roll has a lower hardness drop than the standard nodular iron rolls which resulting in better wear resistance,especially for rolls with deep grooves.
The shell material of acicular nodular iron rolls consists of nodular graphite and carbides in an acicular abinitic matrix. The alloy of acicular roll material is higher than the pearlitic rolls. Acicular nodular iron rolls are more wear resistant than pearlitic nodular iron rolls under the condition of same hardness. But pearlitic nodular iron rolls have superior resistance to thermal cracking.
Nodular cast iron rolls are used primarily in the billet and roughing satnd of hot rolling mills, sections mills, tube mills, bar mills and wire rod mills.
