The present invention belongs to the technical field of metallurgy, and relates to alloy roll ring for hot rolling seamless steel tube and production method thereof. The alloy roll ring is composed ofan outer layer and an inner layer two-layer centrifugal composite structure, the outer layer of the roll ring is made of the high manganese molybdenum cast iron, and the inner layer is made of the graphite steel. The production method of the alloy roll ring adopts a centrifugal compound casting process, and the process also comprises: cold-type paint spraying, metal liquid smelting and deterioration treatment, centrifugal casting, pit insulation, heat treatment. According to the Alloy roll ring for hot rolling seamless steel tube production and production method thereof, the working layer ofthe invention adopts the high manganese molybdenum cast iron material, makes full use of the characteristics of manganese with high hardness and strength of strong carbide elements and the high toughness and wear resistance of molybdenum, to realize the high strength, high wear resistance and resistance to cold and heat fatigue. Compared with ordinary pearlite and bainite roll ring, its productioncost is reduced by 10 to 15%, and its service life can be increased by 2 to 3 times, which can replace traditional pearlite and bainite roll ring.
