Beschreibung
Zusammenfassung:	PURPOSE:To obtain a centrifugally cast sleeve roll combining wear resistance, crack resistance, and high toughness by integrally joining, by melting, an outer layer material having a specific composition consisting of C, Si, Mn, Cr, Mo; V, Nb, and Fe to an inner layer material composed of ductile cast iron with specific composition. CONSTITUTION:An outer layer material and an inner layer material are integrally joined by melting by a centrifugal casting process and formed into a sleeve roll. The outer layer material has a composition which consists of 1.0-3.5% C,
