Centrifugal Cast steel roll
The mechanical properties are improved due to pressure of chilled surface structure and the change of pine tree-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.
For wire, bar and small section or light-duty material rod mills.
