An experimental investigation has been conducted with respect to the influence of permanent magnet stirring (PMS) under different rotation speeds (ω=60, 120 and 150r/min) and center magnetic flux densities (B=757 and 1080Gs) on the solidification of Sn-20wt%Pb alloy. The magnetic field was generated by a pair of arc-shaped NdFeB permanent magnets with a gap that could be adjusted to obtain the required...
