Abstract

PURPOSE:To obtain a roll which is highly resistant to abrasion and cracking and is resistant to accidents by combining shell cast iron of good abrasion resistance of specified component composition and core material gray cast iron of small residual stress and of required mechanical strength. CONSTITUTION:The composition of a shell material is specified at 3.0-3.6 T.C by %, 0.1-1.1 G.C, 0.5-0.9 Si, 0.4-1.3 Mn, 3.0-5.0 Ni, 0.8-2.2 Cr, 0.2-0.6 Mo, <=0.3 other trace elements, and the balance substantially Fe. This yields 70-85 hardness H, 0.5-8% graphite areas and 30-50% cementite areas. Next, the composition of a core material is specified at 2.9-3.7 T.C by %, 1.6-2.3 G.C, 0.7- 1.5 Si, 0.4-1.0 Mn, 0.3-2.0 Ni, 0.4-1.1 Cr, 0.05-0.4 Mo, <=0.4 other trace elements, and the balance substantially Fe. This yields 30-60 hardness H, and 8,000-16,000kgmm.<2> Young's modulus.
