The invention discloses a high-carbon high-vanadium high-speed-steel complex roll. The outer layer of the high-carbon high-vanadium high-speed-steel complex roll comprises, based on weight percent, C: 1.8%-3.0%, V: 3.0%-6.0%, Cr: 4.0%-6.0%, Mo: 3.0%-6.0%, W: 1.0%-3.0%, Nb: 1.0%-5.0%, Co: 1.0%-5.0%, Si: <1.0%, Mn: <1.5%, P: <0.04%, S: <0.04%; Y: 0.05%-0.20%, Ti: 08%-0.25%, Mg: 0.03%-0.12%, Zr: 0.04%-0.18%, Te: 0.02%-0.12%, the residuel of Fe, the total of 100%. The roll is produced by smelting using electric furnace, casting and forming using centrifugal casting, heat treatment comprising quenching and tempering treatment. The high-speed-steel roll has high rigidity and strength, good toughness and wear resistance, and good anti-thermal fatigue, without roll breakage and desquamation in use. The application of the inventive roll can reduce the consumption of roll, improve the work rates of roll, prolong roll changing cycle, improve the surface quality of roll, with good economic and social effect.
