With the methods of macrostructure observation and temperature measurement, the paper has studied the influence rules of static magnetic field on 2024 aluminum alloy solidification structure and solidification rate. The conclusions can be concluded as follows: the static magnetic field can inhibit the growth of columnar crystals and promote the growth of equiaxed crystals; when the magnetic flux density is increased, the grain refining effect is better, the solidification rate of 2024 aluminum alloy increases remarkably, and the full solidification time is shorter; the reasons of grain refinement may be that the thermo-electromagnetic convection effect related to Peltier effect is stronger than electromagnetic braking effect, which can enhance the heat transfer and fluid flow in the solidification front, and that undercooling temperature is enlarged.
