摘　　要：设计了一个双辊薄带连铸机动态物理模拟实验装置，利用超声波浪高仅对双辊熔池液面波动进行了实验测定．重点研究了不同水口结构、拉速（转速）、熔地高度以及插入深度等参数对熔池内液面波动的影响，从而为优选出满足双辊薄带连铸布流要求的水口结构尺寸提供依据．An experimental setup which can model dynamically the twin roll strip casting was established. By using the ultrasonic level detector, the level fluctuations in the pool have been measured. It was mainly studied that the influences of the submerged nozzle's types, casting rates, pool heights and submerged nozzle's immersion depths on the level fluctuations in the pool. The experimental results provided a basis to further optimize nozzle for meeting with the feeding in the pool of twin roll strip caster.
