Abstract A mercury model was developed to investigate the control of the jet–pattern magnetic field on the flow in medium and heavy slab continuous casting mold. The velocities in mold with and without magnetic field was measured by ultrasonic Doppler velocimeter. The influences of the magnetic field on the flow discharged from the nozzle, the flow in the mold, the flow at the meniscus and washing intensity to wall were analyzed and studied. The results showed that the flow discharged from the nozzle is suppressed, and dissipated before impinging against wall, the flow in the upper eddy is strengthened, the flow in the lower eddy is weakened, and the flow at the meniscus is improved by jet–pattern magnetic field. Compared with electromagnetic braking (EMBr) ruler, the brake effect of the the jet–pattern magnetic field on the flow discharged from the nozzle and the flow at the meniscus are the better.
