Centrifugal Casting Definite Chilled Cast Iron Roll and Ring


The mechanical properties are improved due to presence of chilled surface structure and the change of pinetree-like structure. The hardness and type of matrix of roll depend on the conditions of application. The roll produced with centrifugal method basically eliminates the presence of graphite in its work layer while the core is made of nodular cast iron, increasing as a result, both the wear-resistant and breaking strength.

Mechanical Properties
Hardness of shell HSD65-85
Hardness of neck HSD35-48
Tensile Strength of core ≥450Mpa
