A recycling method of a tube mold is provided to ensure that a product production cost due to continuous casting and maintenance cost of continuous casting facilities are less consumed by allowing a tube mold that has been used for a certain time to be reused. A recycling method of a tube mold comprises: a plating exfoliating step(S1) of exfoliating a plating layer of a tube mold having a worn part formed thereon; an inner and outer diameter finishing step(S2) of grinding the plating layer-exfoliated tube mold; a tube mold pressing step(S3) of inserting a mandrel into the tube mold and pressing the mandrel inserted tube mold to eliminate the worn part formed on the tube mold; an outer diameter plating step(S4) of forming a plating layer on an outer peripheral surface of a lower part of the tube mold; a tube mold cutting step(S5) of cutting and machining a lower part of the tube mold of which length and outer diameter have increased as compared with those of an initial tube mold by the tube mold pressing step and the outer diameter plating step; an inner diameter finishing step(S6) of grinding an inner peripheral surface of the tube mold; an inner diameter plating step(S7) of forming a plating layer on an inner peripheral surface of the lower part of the tube mold; and an outer diameter finishing step(S8) of grinding an outer peripheral surface of the tube mold.
