| 摘 要： | 通过水模型模拟实验,选用苯胺模拟夹杂物,有机硅油模拟中间包渣,研究了中间包吹氩去除夹杂物的效果;通过刺激—响应法测定中间包吹氩RTD曲线,探讨了中间包吹氩去除夹杂物的过程和机理。研究结果表明:在中间包吹氩条件下,活塞区体积分数最大的吹氩位置不一定会得到最大的夹杂物去除效果,在注流区附近吹氩,不但可以提高气泡捕捉夹杂物颗粒的概率,而且促进了夹杂物颗粒相互碰撞长大,去除夹杂物效果更为明显。 |

| Abstract: | The effects of inclusion removal in tundish with argon bubbling were investigated by choosing aniline simulated as inclusions and silicone oil as slag in a water model.And RTD curves had been measured by means of irritating-response method.The process and mechanics of inclusions removal were researched.The results show that in gas bubbling tundish,the ratio of inclusion removal may not be at maximum with the biggest proportion of piston volume.When gas purging at the injection flow area,the probability of b... |
