Centrifugal cast pipe and the centrifugal casting steel tube, especially suitable for centrifugal casting of heat resistant steel.Due to the centrifugal casting process to produce centrifugal casting tube, not only high efficiency and pipes of compact structure, therefore, western countries use centrifugal casting process to produce more.Centrifugal casting pipe according to the characteristics of can be divided into water-cooled metal mold casting, centrifugal casting pipe, coating metal mold centrifugal cast pipe, resin sand lined centrifugal cast pipe, mould centrifugal cast pipe.Coating metal mold centrifugal casting pipeCoating metal mold centrifugal casting tube, also known as hot molding centrifugal cast pipe, its structure is characterized by metal mold without a jacket, the host does not make the horizontal motion, use short chute, within the mold spray a layer of surface coating, can be obtained without white as-cast centrifugal tube, this machine has simple structure, low cost, the replacement of mold is convenient, and long mould life, cast pipe diameter is not restricted, can produce grey iron tube and iron tube ball.
