The invention discloses a heat treatment method for an inlaid backup roll sleeve. The heat treatment method comprises the following steps: A, smelting a steel ingot, and then forging a roll sleeve blank, followed by rough machining and flaw detection; B, performing hardening and tempering on the roll sleeve blank, heating the roughed roll sleeve, and performing tempering on the roll sleeve; C, performing semi-finish turning machining and flaw detection on the roll sleeve; D, hoisting the semi-finish turning machined roll sleeve to a power-frequency quench machining tool, carrying out overall induction heating by using a dual-power frequency power source, adopting a water quenching method; subsequently, carrying out tempering; E, detecting metallographic structures of inner and outer surfaces of the roll sleeve, and detecting residual stress and hardness of the outer surface; F, performing finish machining on the roll sleeve; and G, assembling a roll shaft, and performing finish machining on the assembled roll. The heat treatment method for the inlaid backup roll sleeve of the present invention meets the requirements in structure, hardness and residual stress aspects, and meanwhile, such properties as abrasive resistance and contact fatigue strength of the roll sleeve also are improved.
