Abstract

PURPOSE: To obtain a composite sleeve roll with superior wear resistance by using a high Cr material as a shell material and nodular graphite cast iron as a core matrial and melting and uniting them by centrifugal casting.
CONSTITUTION: Molten metal for a shell consisting of 2.0W3.2% C, 0.5W1.5% Si, 0.5W1.5% Mn, ≤0.1% P, ≤0.1% S, 0.8W2.5% Ni, 10W25% Cr, o.5W2.0% Mo and the balance essentially Fe is cast by centrifugal casting. While part or all of the inside is unsolidified, molten metal for a coe consisting of 2.8W3.8% C, 1.8W3.2% Si, 0.3W0.8% Mn, ≤0.1% P, ≤0.06% S, ≤1.5% Ni, ≤0.8% Cr, ≤0.6% Mo and the balance essentially Fe and having 0.02W0.1% residual Mg content by Mg treatment is cast and united with the shell metal to obtain a composite sleeve roll with 65W80Hs shell hardness for rolling wide flange beam.
