1. Relying on the beginning from the outside of the contact with the mould of the directional solidification, made no casting shrinkage and the quality of the clip into the foreign body extremely dense.2. As a result of the action of centrifugal force can be achieved when average thickness of hollow cylindrical products.3. Because there is no influence of solidification shrinkage factor, the casting stress small products can be achieved.4. Because of the compact centrifugal casting organization, the prosperity of the columnar crystal, so has good high temperature oxidation resistance, carburizing resistance and high temperature strength.5. Available in 800-12001 ° C temperature, 3-4 mpa long-term continuous work under pressure.
