The frequency of vortex increases with the augment of the casting speed, and decreases with the augment of the immersion depth and nozzle angle.
漩涡的出现频率随拉速的增加而增加，随水口浸入深度的增加而减小，随水口张角的减小而增大；
The results show that the submerged nozzle ingate angle and depth of its immersion should decrease gradually with the lowering of casting speed.
结果表明，随着拉速的降低，水口的上倾角大小和浸入深度应逐渐减小。
