Centrifugal casting is a casting method in which liquid metal is poured into a rotating mold. Under the action of centrifugal force, filling and solidification are completed.
Centrifugal casting has a history of over a hundred years. The first patent was proposed by the British Ercardt in 1809, and it was not gradually promoted for industrial production until the beginning of the 20th century.
Centrifugal casting is now a widely used manufacturing method, often used to produce cast pipes, sleeves, rolls, roller tables, etc.
In the 1940s, the technology of composite metal rollers of centrifugal casting began to be used in the industry. The production process was not perfect, and it was limited to the production of composite bushings of several materials.
In the mid-1970s, Composite metal rollers of centrifugal casting was fully developed and applied. In addition to the advantages of centrifugal casting, Composite metal rollers of centrifugal casting technology can meet the higher requirements of the material for the inner and outer layers due to the different materials used for the inner and outer layers. , both high wear resistance and a certain degree of strength and toughness are required. In view of the unique process characteristics of centrifugal composite casting, it has achieved significant technical and economic effects in the production of wear-resistant castings.
