Abstract
PURPOSE: To obtain a composite roll with high wear resistance by melt-bonding a metal having higher wear resistance than a core material of a roll having a prescribed shape to the surface of the core material and forming a structure in which eutectic carbide in the wear resistant metal is almost uniformly dispersed in the matrix grains.
CONSTITUTION: A steel contg. 0.3W1wt% C is used as a core material of a roll, and a steel contg., by wt., 1.5W3% C, 7W20% Cr, ≤2% Ni, ≤2% Mo and ≤2% V as a wear resistant metal. The wear resistant metal is melt-bonded to the core material by build-up welding applying electroslag welding. The resulting roll is hot- forged to form a martensite structure in which eutectic carbide in the wear resistant metal is almost uniformly dispersed in the matrix grains. Hardening and tempering are then carried out to obtain the desired composite roll.
