In order to prepare liquid Al-Sn alloy with uniform distribution of Sn

the liquid Al-Sn alloy in crucible with straight blades arranged on inner wall was stirred by electromagnetic stirring.The influences of blade arrangement angles on the distribution of Sn in liquid Al-Sn alloy were investigated

and the processing parameters were determined to obtain liquid Al-Sn alloy with uniform distribution of Sn.The results show that the radial distribution of Sn in crucible is determined by the angle β between blade and the radial of crucible

and the axial distribution of Sn in crucible is controlled by the angle γ between blade and the axes of crucible.With β of 28°and γ of 28°

the liquid Al-20Sn alloy with uniform distribution of Sn in radial and axial direction can be prepared.
