Abstract
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 (ΔP), the maximum anglar velocity(ω 0max/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 ΔP plus the static pressure. The static pressure depends on the melt height, while ΔP 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 ω 0max increases with H and D 0.
