PURPOSE: A method for manufacturing rolling rolls is provided to have excellent binding force between an outer lamination and an inner lamination because an injection time of molten steel for the inner lamination is determined by the internal temperature, surface temperature, and vibration value of the centrifugal mold. CONSTITUTION: A method for manufacturing rolling rolls is as follows: a step of injecting molten steel for an outer lamination into a rotatable centrifugal mold of a centrifugal casting machine; a step of getting data on the internal temperature, surface temperature, and vibration of the centrifugal mold having the outer lamination; and a step of separating the centrifugal mold from the centrifugal casting machine and injecting molten steel for an inner lamination into a hollow part of the centrifugal mold to form the inner lamination if the value of the data is within a predetermined reference range.
