Abstract

PURPOSE: To obtain a roll with even surface hardness and superior wear resistance by forming the build-up welded surface layer of a roll for hot rolling with a high- carbon chormium steel contg. a specified amount of Nb.
CONSTITUTION: When a build-up welded hard layer is formed on the surface of a roll for hot rolling by a gas arc welding method using a covered electrode or a submerged arc welding method, a high-carbon chromium steel having the following composition is build-up welded in 5W100mm thickness. The composition contains 0.8W2.4% C, 0.2W3.0% Si, 0.3W3.0% Mn, 9.0W17.0% Cr and 1.5W14.4% Nb or further contains one kind of ≤4.0% Mo, ≤4.0% W and ≤2.0% V and satisfies Nb/C=1.0W6.0. Thus, a roll for hot rolling having a build-up welded surface layer with even hardness, superior crack and water resistances can be manufactured.
