PURPOSE: To improve efficiency and yield by fitting plural projectshaped chillers in inside of a metallic mold and cooling outer shaped face and side face in a sleeve roll at the same time.

CONSTITUTION: The chillers 11 having project-shape and divided into plural number to circumferential direction, are set in the inner face in the metallic mold 1, and both ends of the metallic mold 1 are joined with an upper mold frame 2 and lower mold frame 3 to constitute the whole mold. The mold constituted in such way, is laid on rotating roller 6 and molten metal is poured from pouring part 5 while rotating at the prescribed velocity to execute the centrifugal casting to plural sleeve 7. By this method, plural roll products can be cast at the same time, and the improvements of efficiency and yield are expected, and as one piece of the metallic mold can be commonly used to many sizes, coat of the metallic mold can be reduced.
