摘要:
The effect of electromagnetic stirring in submerged entry nozzle (SEN) was simulated through setting a swirl blade in SEN of the hydromechanics mode. Which can make the flux spiral. The vertical velocity and horizon velocity of liquid in the model were measured using ultrasonic Doppler velometer(UDV). The effectiveness of electromagnetic stirrer and technological parameters were examined. Following issues were obtained: (1) Swirling flow can improve the flow field in mold; (2) The dashing depth can be reduced effectively; (3) The reversing flow and heat transmission of meniscus were enlarged; (4) The horizon circulating formed at liquid surface, so the activity of liquid level and the effectiveness of molten slag were increased.
