摘要

The pressure distribution in the pouring basin during the centrifugal casting of the alloy Ti-15V-3Cr-3Sn-3Al(Ti-15-3) is analyzed. Relationships between an extra pressure (Delta P), the maximum anglar velocity (omega(0max)(r/min)), the height of melt (H) and the diameter of pouring basin (D-0) are investigated. The calculation results show that the pressure affecting casting consists of Delta P plus the static pressure. The steric pressure depends on the melt height, while Delta P is controlled by metal liquid density and rotating angular velocity. The pouring basin height and diameter follow a certain functional relation. Idealy the metal liquid should be half as high as that of the pouring basin. The allowed maximum angular velocity omega(0max) increases with H and D-0.
