为了抑制浇钢过程中涡流卷渣，提高钢水洁净度，本研究对影响自由表面涡流形成的关键因素进行了分析。研究发现科里奥利力对涡流形成影响不大。初始切向扰动是涡形成的主要因素。并且当喷嘴位置为中心或偏心时，初始切向速度、喷嘴直径对临界高度的影响是不同的。钢水的物理性能对临界高度影响较小。讨论了计算高度的公式。
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.
