Notes:
In this paper, numerical simulation software of AnyCasting was adopted for simulateprocesses of titanium aluminum alloys filling and solidifying. Pour temperature, pressure head androtate speed had an important effect on casting quality. The former parameters as factors orthogonalexperiment L7 (33) was carried out and the experimental scheme was optimized. The results showedthat as the pour temperature rising the filling time had no change, solidifying time had a large increaseand casting defect tendency tended to little. Filling time and solidifying time decreased with thepressure head rising and casting defect tendency changed from little to large. The effect of rotatingspeed on filling time was as that of pressure head, solidifying time had little change and castingdefects tendency of casting changed from little to great.With the optimized parameters of casting temperature of 1650°C, pressure head of 0.2m androtating speed of 200r/min the investment cast filling and solidifying simulations was made out. Theresults showed that in the optimized simulation the liquid metal filled mold from the top down, fillingcourse was smooth and complete and temperature field was even. Through analyses of casting defectsthe optimized scheme proved to be logical
