Abstract

PURPOSE: To decrease the material loss of sleeve for rolling and enhance the economy, by casting a hollow roll having stepped parts smaller in diameter than the outside diameter of cast roll provided at the both ends in the axial direction.
CONSTITUTION: Stepped die faces 12a having stepped parts 12, 12 smaller in diameter than the outside diameter of a raw material l3 projecting to both ends in the axial direction of the raw material 13 are preliminarily formd on bands 10, 11 at both ends of a centrifugal casting die 9 by using an end plate and a sand mold, Molten iron is poured in through the central opening in one band 10 from a pour trough or the like, and the die 9 is rotated. As a result, an outer layer 4 and an inner layer 5 are formed by centrifugal casting in this order, so that the hollow mateial 13 having stepped parts 12, 12 projected to the both ends in the axial direction may be obtained. Holding these stepped parts 12, 12 with a chuck 8, the material is cut into sleeves 7 of specified width. Hence, the material loss is extremely decreased, and the economy is enhanced.
