Explanation

① A method of foundry in which liquid metal is wound into a mold rotating along the axis of symmetry and solidified and fed under the action of centrifugal force. Under the action of centrifugal force, liquid metal forms a uniform cylinder along the inner surface of the mold, and the wall thickness of the cylinder is controlled by the amount of metal casting. Centrifugal force can accelerate the separation of gas and inclusion from liquid metal, promote directional solidification, help feeding, refine grains and compact the structure. The centrifugal casting method is often used to produce tubular and cylindrical castings (without core), and can also be used to produce cylindrical parts with high requirements for surface quality, such as roll. centrifugal casting can be divided into horizontal centrifugal casting, vertical centrifugal casting and inclined centrifugal casting according to the angle between the mold rotation axis and the ground. ② The process of pouring liquid metal into the combined mold rotating along the vertical axis to form multiple castings at one time. The position of rotation axis serves as both sprue and feeder. The effect of centrifugal force makes the casting structure dense, with few gases and inclusions. Commonly used in the production of small castings with high quality requirements.
