Combined with a mercury experiment, a Reynolds time-average model was applied to investigate the effects of magnetic flux density on flow in the mold cavity with different electromagnetic braking (EMBr) and on the process. The results show that the Reynolds stress model (RSM) can accurately reflect flow changes of the mold with EMBr. Nozzle jet profile and washing intensity to the thin wall of mold are varied with alteration of magnetic flux density. The upper portion of the magnetic field can obviously inhibit the surface horizontal velocity and turbulence. However, considering the melting of powder and impingement depth, the upper portion of the magnetic flux density should not be too high.
