Abstract: A casting is produced by centrifugal casting in which molten metal of gray cast iron is poured into a cavity formed in a mold during rotation of the mold under centrifugal force. The casting comprises a gray cast iron region and a spheroidal graphite cast iron region from which the graphite structure is gradually transformed toward the gray cast iron region through an intermediate region of vermicular graphite. The spheroidal graphite region and the intermediate region are formed by a reaction of the molten metal with spheroidizing agent in the cavity during rotation of the mold and solidification of the molten metal. The spheroidizing agent is provided in the cavity to a position where the casting is to be increased in strength and abrasion resistance. The spheroidizing agent can be introduced along with the molten metal through the pouring gate into the mold cavity to a defined position of casting.
