In order to adapt to the production of different castings, various forms of centrifugal casting machines have been designed and manufactured. Centrifugal casting machine can be divided into vertical centrifugal casting machine and horizontal centrifugal casting machine according to the direction of rotating shaft, and horizontal centrifugal casting machine can be divided into cantilever type and roller supported type (as shown in the figure).
According to the characteristics of long length of tube parts and high quality of corresponding mold, the roller supported horizontal centrifugal casting machine with large bearing capacity is selected for centrifugal casting of furnace tube. The mold of this type of centrifugal casting machine is not directly connected with the driving spindle, but is supported by two groups of rollers. After the motor drives the roller to rotate, the friction between the roller and the mold is generated, and the friction drives the mold to rotate.
