Abstract

A ROLL OUTER LAYER MATERIAL FOR HOT ROLLING CONSISTS ESSENTIALLY, AS ANALYZED IN WEIGHT PERCENT, OF 2.5-4.0, 6.0-20R, 3.0-10.0V, 0.6-5.0NB, 2.0-15MO, 3.0OR BELOW SI, 3.0OR BELOW MN, C, V, NB AND CR SATISFYING A FOLLOWING FORMULA (1), 10.5() < 6.5.C () - 1.3.V () - 0.7.NB () < 2.CR () - 2 () ... (1) , AND THE BALANCE BEING FE AND INCIDENTAL IMPURITIES. A METHOD OF MANUFACTURING A ROLL FOR HOT ROLLING COMPRISES THE STEPS OF CENTRIFUGALLY CASTING AN OUTER LAYER MATERIAL HAVING THE ABOVE COMPOSITION, CENTRIFUGALLY CASTING GRAPHITE STEEL CONTAINING 0.5OR ABOVE OF C AS AN INTERMEDIATE LAYER, AND CASTING AN AXIS MATERIAL WHICH IS A SPHEROIDAL GRAPHITE CAST IRON, A FLAKE GRAPHITE CAST IRON OR A GRAPHITE STEEL. C IS PRESENT IN THE INTERMEDIATE LAYER IN AN AMOUNT WHICH SATISFIES A FOLLOWING FORMULA (2), C (INTERMEDIATE LAYER) ~2.0 - 0.5 (C - 0.2V - 0.11NB) (OUTER LAYER )...(2)
