The centrifugal casting method of copper casing, also known as brass bush, involves casting molten copper into a rapidly rotating centrifuge, where it is then compacted by centrifugal force. This technique is commonly used in the manufacture of cast pipes and copper casings, as well as in the manufacture of seamless steel pipes and other products.
In the centrifugal casting process, a number of process issues must be addressed to ensure optimal casting quality and productivity. Some things to consider include mold rotation speed, pouring system, amount of metal poured, solidification, metal filtration, use of coatings, casting temperature, and release process.
Mold rotation speed is a key factor in centrifugal casting. Too low a speed can cause uneven mold filling and surface defects, while too high a speed can cause cracks and segregation. Therefore, the speed must be selected carefully to ensure good casting quality.
The pouring system is also important in centrifugal casting. This includes the design of the pouring cup and tub to ensure even metal distribution and reduce slag and metal spatter.
At the same time, the amount of metal poured must be controlled to ensure the desired inner size. The use of slag forming agents and metal filters helps remove slag and purify molten metal.
In addition, the use of paint must be adjusted according to requirements to facilitate casting removal. Casting temperatures must also be carefully controlled, with pouring during centrifugal casting generally carried out at slightly lower temperatures than gravity casting.
Casting stripping is also an important stage in this process, which must be carried out carefully to ensure production efficiency and good product quality. By considering all these factors, centrifugal casting of copper casings can be carried out efficiently and produce high quality products.
