Zusammenfassung:	PURPOSE:To obtain a composite roll by centrifugal casting free from segregation and uniform in wear resistance and cracking resistance by integrating an outer layer material having a specified compsn. constituted of C, Si, Mn, Cr, Mo, V, Nb and Fe onto an axial material made of cast iron by welding. CONSTITUTION:An outer layer material is integrated by welding to the surface of an axial material made of common cast iron or ductile cast iron, if required, via an intermediate layer by a centrifugal casting method to obtain the objective composite roll. The outer layer material contains 1.5 to 3.5% C,
