Abstract

A centrifugally cast composite roller in which an outer layer formed by centrifugal casting and an inner layer made from ductile cast iron are integrally welded wherein: the outer layer has a chemical composition containing at least 0.8 to 3.0% of Cr 1.5 to 6.0% of Mo and 1.8 to 5.5% of V by mass and comprises an Fe based alloy in which the graphite area ratio in the metal structure is 0.3 to 10%; the inner layer has a body core part welded to the outer layer and shaft parts extending integrally from both ends of the body core part the total amount of Cr Mo and V at end sections of both shaft parts being 0.15 to 2.0 mass% and the difference in the total amount of Cr Mo and V between one shaft part and the other shaft part being equal to or greater than 0.2 mass%.
