Change rule of sectional area of melts during vertical centrifugal casting process

The filling and solidification of titanium alloy melts in the vertical centrifugal filed were investigated. The results show that the coriolis force plays an important role in the change of melts flow direction. With the action of the centrifugal force and coriolis force, the melts stick one of side of the mould to fill and the side is opposite to the rotational direction. The whole filling process includes two filling parts: forward filling and back filling. During the forward filling process, the sectional area of the mould without the ingate decreases with the increase of filling length, but which is changeable with the increase of the filling length for the mould with ingate. The rotational direction plays an important role in the filling sequence of the mould with ingates.
