摘要：
To suppress slag entrapment by vortexes during steel teeming, and to improve steel cleanliness, key factors affecting free surface vortex formation have been analyzed in this study. It was found that Coriolis forces have little effect on vortex formation. The initial tangential disturbance is the main factor for vortex formation. And when the nozzle position is central or eccentric, the effects of initial tangential velocity, nozzle diameter on the critical height are different. Physical properties of liquid steel have a small effect on the critical height. A formula for calculating the height was discussed.
