摘要
The filling rules of TiAl based alloy melt in centrifugal field has been concluded basing on the mathematical model. Results show that centrifugal field has an important influence on the filling process and melt fills the mould with variational cross-section and inclined angle. Cross-section area decreases and inclined angle increases respectively when filling length increases, and the change becomes more obviously near the entrance. In addition, the forming reasons of entrapping poles and prejudicial shrinkage existing in the TiAl based alloy valves poured in permanent mould during the centrifugal casting process have been discussed.
