This method for producing a rolling roll (10) provided with a roll body member (13) at which a tinkered build-up layer (12) is formed at the outer periphery of a core (11) comprising Cr-Mo steel or carbon steel, and a Cr-Mo steel shaft (14, 15) provided to both sides in the axial direction of the core (11) has: a pre-heating step for the joining ends (16-19) of the roll body member (13) and/or the shaft (14, 15); and a friction welding step for rotating the shaft (14, 15) while pressing against the core (11), causing friction heating of the joining ends (16-19), and then strongly pressing to weld. A production device (20) has: a first and second grasping means (29, 23) for the roll body member (13) and the shaft (14, 15); a rotating means that rotates the shaft (14, 15); a pressing means (24) that presses the core (11) and shaft (14, 15) in the axial direction; and a pre-heating means (31) that pre-heats the joining ends (16-19) of the roll body member (13) and the shaft (14, 15). |
