Centrifugal Chilled Cast Iron Rolls and Rings

The outer layer has a chilled surface tissue, and the mechanical properties are also improved due to the change of the dendrite structure. The hardness of the roll and the type of the matrix tissue depend on the conditions of use. The centrifugal casting process makes the whole roller working layer inside the basic no graphite, the core of ductile iron, in improving the wear resistance of the roll at the same time, the fracture resistance has also been improved.
