CENTRIFUGALLY CAST HIGH CHROMIUM ROLL

CENTRIFUGALLY CAST HIGH CHROMIUM ROLL

PURPOSE:To prevent the embrittlement of a shaft core material due to the remelting diffusion of Cr in an outer shell layer into the shaft core material by providing an intermediate layer between the outer shell layer composed of high Cr type material excellent in resistance to surface roughness and...

description PURPOSE:To prevent the embrittlement of a shaft core material due to the remelting diffusion of Cr in an outer shell layer into the shaft core material by providing an intermediate layer between the outer shell layer composed of high Cr type material excellent in resistance to surface roughness and wear resistance and the shaft core material composed of ductile case iron reduced in elastic modulus, capable of reducing thermal and residual stresses, and excellent in toughness. CONSTITUTION:This high chromium roll is constituted by integrally binding an intermediate layer 2 composed of graphite steel consisting of, by weight, 1.0-2.0% C, 1.6-2.4% Si, 0.2-1.0% Mn,
