Abstract

PURPOSE: To obtain a composite roll for continuous casting with superior oxidation wear resistance and heat check resistance by welding a steel for build-up welding contg. a specified amount each of C, Si, Mn, Ni, Cr, Mo and Ce to the surface of a core material for a steel roll contg. a specified amount each of C, Si, Mn, Ni, Cr, Mo and V by build-up welding.
CONSTITUTION: A core material for a steel roll contg., by wt., 0.2W0.5% C, <1.5% Si, <2% Mn, <2% Ni, 2W6% Cr, 1.5W2% Mo and 0.2W2% V is prepared. A steel for build-up welding contg., by wt., 0.05W0.7% C, 0.1W1.2% Si, 0.2W1.5% Mn, 0.2W2% Ni, 10W20% Cr, 0.2W20% Mo and 0.2W3% Ce is welded to the surface of the core material by build-up welding. To the steel for build-up welding may be added 0.1W2% in total of one or ≥2 kinds among Ti, V, Nb and Zr.
