In the production process of centrifugal copper casting, it is very important to determine the speed of the casting mold, which directly affects the quality of the casting and the cost of production. If the speed is too low and the centrifugal force is insufficient, it is easy to cause poor filling of castings, and rain will appear in horizontal centrifugal casting; but too high speed will not only waste resources, but also cause defects such as longitudinal cracks and component segregation in castings.
