Centrifugal casting high speed rotary mould is injected liquid metal, the metal liquid under the action of centrifugal force, full of mold and casting techniques and methods.Centrifugal force makes the liquid metal in the radial well full of mold and casting of the free surface;No core can obtain cylindrical inner hole;It is divided into horizontal and vertical centrifugal casting, centrifugal casting mould rotation axis in the level of state or with small Angle (4 °) horizontal centrifugal casting is called horizontal centrifugal casting.Cast a rotating axis are in a state of vertical centrifugal casting is called the vertical centrifugal casting, and inclined shaft centrifugal casting, but rarely used.Centrifugal casting is not only applied in centrifugal cast pipe also applied to other aspects, such as double metal iron roll;Heat resistant steel roller furnace bottom;Special steel seamless steel tube and so on the many kinds of processing technology is in need of centrifugal casting, is one of the important processing industry.
