| Abstract: | According to the similarity theory a physical model for simulating the level fluctuation and fluid mixing characteristics in the melt pool is established. The relationship between the size and structure of the nozzle as well as the operating parameter and the level variation and fluid mixing condition has been quantitatively determined by measuring the dynamic variation of the fluid flow in the pool with an ultrasonic level detector and a conductometer. The experimental results provides a basis for optimizing the design of the submerged nozzle of the twin roll strip caster and its operating parameters. |
