Mathematic model of solid fraction during rheo-casting by the cooling sloping plate process

A mathematic model of the solid fraction during rheo-casting by the cooling sloping plate process was established, and the efiects of the process parameters on the solid fraction were analyzed. The calculation results show that the experimental result is approximately agreed with the calculation value. The efiect of the casting temperature on the change rate of the solid fraction is not obvious. But the beginning solidiflcation length is greatly in∞uenced by the casting temperature. The beginning solidiflcation length increases with the increment of the casting temperature. The efiect of the sloping angle on the solid fraction becomes obvious with the increment of the sloping plate length. The solid fraction increases sharply with the decrease of the initial thickness of the melt. The melt initial thickness between 15 and 20 mm is suggested.
