Physical Simulation of Infiltration Flow during Centrifugal Casting Titanium Alloy Melts Feeding

Abstract:

By means of similar physical simulation method, the variation of infiltration volume is thoroughly studied during titanium alloy melt feeding in centrifugal field, and compared with the big cross-section filling process. The results show that the infiltration volume in feeding process increases with increasing the feeding time and velocity or decreasing the fluid viscosity and eyelet number of porous medium. When the mould rotates clockwise, the left part relative to the right part in running channel starts feeding and infiltration firstly. The infiltration volume decreases against the big cross-section macro-filling flow in the same time.
