A profiled casted roll and a preparation method therefor and a profiled composite-casted roll and a preparation method therefor. The structure of the profiled composite-casted roll is formed by compositing two parts, viz. an inner layer (3-1) and an outer layer (3-2), the body of the roll is shaped as a curved surface, and a central hole is formed along the central axis of the roll. The preparation method designs a mold into two parts, viz. a casted inner profile (4-2) and a casted outer profile (4-1, 5-1), by means of the curved surface design of the body of the roll and a profile casting design, and a profiled composite-casted roll having roll body working layers which are abrasion resistant, impact resistant, and cold or heat shock resistant and a core in high strength and high toughness is prepared by respectively casting, which method meets the service requirements for a roll used for steel pipes and equipments such as a cold-formed profiled steel rolling mills etc., improves the service life of the roll, saves alloy materials, and reduces the manufacturing cost.
