The invention discloses a composite overlaying manufacturing method of a casting roller. The method comprises the steps of 1) manufacturing a base body of the casting roller, and processing the surface of the base body; 2) preheating the base body; 3) sequentially manufacturing a bottom layer and a transition layer in the periphery of the base body by overlaying; 4) overlaying surface covering layer on the surface of the transition layer to form the casting roller, wherein the surface covering layer comprises the following chemical elements and components in percentage by mass: 0.3 to 0.8% of C, 1.0 to 4.8% of Mn, 0.4 to 6.0% of Si, 4.0 to 8.0% of Cr, 0.01 to 1.0% of Ti, 2.0 to 10% of V, 2.0 to 10.0% of W, 1.0 to 6.0% of Mo, 2.0 to 5.0% of Co, 0 to 0.4% of Ca, 0 to 0.4% of Ba, 0 to 0.5% of rare earth element, and the balance of Fe and other inevitable impurities; 5) tempering the casting roller by slowly heating and slowly cooling, wherein the tempering is performed under a temperature of 560 to 600 DEG C.
